Over time, your keyboard will get dirty, even if you don't eat or smoke at your computer desk. Accumulated dust and dirt negatively affect the operation of the keyboard. In most cases, cleaning the keyboard with compressed air and isopropyl alcohol is sufficient. It is more dangerous if liquid gets on the keyboard - in this case it should be dried immediately. To get rid of sticky keys, take your keyboard apart and give it a good cleaning. After this it will look like new.

Steps

Removing garbage

1. Turn off your computer and disconnect all cables. To protect your hardware from damage, turn off your computer before cleaning your keyboard. If you have a wired keyboard, pull out the cable that connects it to your computer. If you cannot unplug the keyboard (for example, on a laptop), unplug the computer's power cord to reduce the risk of electric shock.

   • Wireless USB keyboard can be disconnected while the computer is on. However, if you have a different type of keyboard, attempting this may damage your computer, so if you're unsure, it's best to turn off your computer first.
   • Remove the batteries from your wireless keyboard, especially if you plan to thoroughly clean the keys.

2. Turn your keyboard upside down to shake out debris. Turn the keyboard over and shake it. Proceed carefully when doing this. This will remove most of the crumbs, foreign particles, hairs and other debris from the keyboard. While doing this, tilt the keyboard at different angles and tap the underside to shake out as much debris as possible.

   • Listen for the sound of debris rolling around in the middle of the keyboard. This sound can be produced by mechanical keyboards and other devices with raised keys. In this case, consider disassembling the keyboard and cleaning it thoroughly.
   • If you are cleaning a laptop keyboard, open it and hold the monitor with one hand and the base with the other.

3. Blow dust and debris out of your keyboard using compressed air. Compressed air is the main means of surface cleaning of the keyboard. Take the can at a 45 degree angle and point it at the keys. Run a stream of compressed air over the keyboard. At the same time, keep the nozzle of the can 1–2 centimeters from the keys.

   • A can of compressed air can be purchased at an electronics or office supply store. It can also be ordered online.
   • To properly clean your keyboard, aim the air stream at different angles. Turn the can in different directions.
   • If you're cleaning a laptop keyboard or membrane keyboard, try holding it while you blow it with compressed air. Hold the keyboard vertically at an angle of approximately 75 degrees to the air stream.

4. Remove stuck debris using a vacuum cleaner. A vacuum cleaner will help remove most of the particles stuck between the keys. If you don't have a vacuum cleaner with a hose, try using a regular vacuum cleaner with a brush attachment. Go over the entire keyboard and take a moment Special attention spaces between keys. Most of the garbage is hidden here.

   • Make sure that all the keys are held securely in place, especially if you are dealing with a laptop. If any key gets sucked into the vacuum cleaner, remove it from the dust container, wash it and put it back in place. Slide the key onto the pin or clip to re-secure it to the keyboard.

5. Wipe the spaces between the keys with a cotton swab soaked in isopropyl alcohol. Moisten the cotton swab just a little so that it doesn't get under the keys. a large number of moisture. Wipe around each key with a cotton swab to remove dust, grease and other dirt. Repeat this several times if necessary and thoroughly clean the sides of each key. When the cotton swab becomes dirty, replace it with a clean one.

   • Isopropyl alcohol dries very quickly, making it a better choice for cleaning your keyboard than plain water. It can be purchased at a pharmacy or supermarket.
   • Instead of a cotton swab, you can use a microfiber wrapped around the tip of a knife. Moisten it with alcohol and wipe the spaces between the keys. This method is better for cleaning mechanical keyboard with raised keys.
   • Be careful with your laptop. Isopropyl alcohol will also work, but there are other components underneath the laptop keyboard that can be easily damaged. Make sure that moisture does not get under the keys.

6. Wipe the keyboard with a cloth soaked in alcohol. To avoid introducing new debris, use a lint-free cloth or paper towel. There should be no alcohol dripping from the fabric after you wet it. Remove dust and other debris from the surface of each key.

   • Take a closer look at the keys you use most frequently (such as the spacebar and enter key). They usually accumulate more dirt. You may have to wipe these keys several times to get them completely clean.
   • Remove dirt from heavily soiled areas using a toothpick. Point the toothpick almost parallel to the key and wipe away the dirt. After this, wipe the key with alcohol.

7. Polish your keyboard with a lint-free cloth. Wipe your keyboard last time to remove remaining dust and moisture. Inspect your keyboard: If there is still dirt on it, consider cleaning it more thoroughly. After cleaning your keyboard, connect it to your computer and check how it works.

   • Any remaining alcohol on the keys should dry within a minute. Water takes longer to dry. If you used water to clean your keyboard or suspect it has gotten wet, wait 24 hours for it to dry completely before connecting it to your computer.

   Cleaning the keyboard from liquid

   1. Turn off the computer and disconnect the keyboard from it. If you spill liquid on your keyboard, turn off your computer immediately. Liquid can seep into the keyboard and damage it, as well as other components if you are working on a laptop. For a wired keyboard, disconnect the keyboard cable from the computer. If liquid gets on your laptop keyboard, turn off the power.

      • To avoid damaging your keyboard and computer, you should take immediate action. The liquid is bad for electronic components. Do not turn on the computer until you have dried the keyboard.
      • Before you disconnect wired keyboard, turn off your computer to avoid damaging it.

   2. Turn the keyboard upside down and try to shake out the liquid. Turn the keyboard upside down over a sink, trash bag, or towel to help the liquid drain out rather than penetrate deeper. Shake the keyboard to loosen any spills that have gotten between the keys. Continue shaking the keyboard until no more liquid drops come out of it.

      • Tilt the keyboard to allow liquid to drain out. If you have a laptop, direct the liquid towards the keyboard - this way it will not damage the monitor and other important components. Turn the open laptop over so that the liquid flows towards the keyboard and flows out of it.

   3. Dry the keyboard with a microfiber cloth. When doing this, hold the keyboard upside down. Try to remove as much liquid as possible with a rag. Don't turn the keyboard back over until you've wiped off everything you can.

      • Paper towels and regular cloths leave behind lint, so try to use microfiber. If you urgently need to wipe your keyboard and don’t have a suitable cloth at hand, use something that leaves less lint. Paper towels, a kitchen towel, or even an old T-shirt will work.

   4. Wait at least 24 hours for the keyboard to dry. Place the keyboard upside down to allow any remaining liquid to drain out. Place a towel under the keyboard to absorb the liquid. Once the keyboard is dry, you can turn it back over.

      • In most cases, 24 hours is enough for all spills to dry. If you have time, dry your keyboard for 2-3 days.

   5. Check your keyboard for sticky keys and other signs of damage. Connect a wired keyboard to your computer or turn on your laptop. Try typing something. Check every key. You may need to remove individual keys and clean them.

      • If you spill something other than water, some keys may stick. In this case, you will have to disassemble the keyboard and clean it inside.
      • If you spill liquid on an expensive laptop, consider calling in the experts. Laptops are much more delicate and more difficult to clean than a regular keyboard. A specialist will be able to check whether the internal components laptop.

   Cleaning the inside of the keyboard

   1. Turn off the computer and disconnect the keyboard. This is necessary for the safety of your computer and your safety. First, turn off the computer, then disconnect the keyboard from it. If you have wireless keyboard, remove the batteries from it.

      • Unplug the power cord if you are using a laptop. Press any key to make sure the laptop is completely turned off.
      • If you are using a wired keyboard, turn off your computer before disconnecting it.

   2. If the keys come loose, use a screwdriver to pry them out. On most modern keyboards The keys are attached to small clips and can be easily removed from them. Use a flathead screwdriver or butter knife to pry up the corner of the key, push slightly upward and try to pull it out with your fingers. You may have to wiggle the key or pry on the opposite side to remove it from its socket.

      • Before pulling out the keys, take a photo of the keyboard mobile phone. This will help you then insert the keys in the correct order.
      • Use a key to remove the keys. It can be ordered online or purchased at an electronics store.
      • If you have any problems removing the keys, check the instructions that came with your keyboard or consult with a professional on how to properly disassemble and clean your keyboard.

   3. If possible, unwind the keyboard and open it. Turn the keyboard over and look for the screws. Some keyboards consist of two panels screwed together. If there are screws on the keyboard, unscrew them and remove bottom panel and clean it separately. Check to see if there are any screws under the labels on the keyboard.

      • If the keys do not extend, you can usually remove the bezel. Then remove the keys, if possible, to better clean the faceplate.

   4. Place the keys in a colander and wash them with warm water. Place a towel near the sink. Run warm water from the tap and place the keys in a colander. Place a colander under warm running water and stir the keys with your hand to thoroughly rinse them. The water will wash away any remaining debris and flow into the holes in the bottom of the colander. After this, place the keys on a towel to dry.

      • If water doesn't remove all the dirt, try using liquid dishwashing detergent. Fill a bowl with warm water and add one tablespoon (15 milliliters) of liquid soap to create a foamy solution. Instead of liquid soap, you can use tablets to clean dentures.

   5. Wash the empty faceplate with warm water and soap. Place the panel in a colander or bowl and wash it with warm water. To remove stubborn dirt, scrub the stained area with a microfiber cloth dampened with soap and water. After this, set the panel aside and wait until it dries.

      • If the keyboard is very dirty, soak the front panel and keys in soap and water for 6 hours. After this, rub the panel and keys and wash away any remaining dirt.
   6. • If the keyboard does not work, check that you have assembled it correctly and connected all the wires to it.
      • If you need to clean your laptop, consider calling a professional for help. A professional can disassemble your laptop, find damaged parts, and safely clean electronic components.
   • On most keyboards, the hardest thing to put back is the spacebar. This key breaks more easily, so consider leaving it in place when cleaning.
   • You usually don't need to take your laptop apart to clean the keyboard. However, if you are handy with electronics, the laptop can be disassembled for more thorough cleaning.
   • Laptops have more delicate keys and are more difficult to replace. The spacebar and enter keys may have separate supports that need to be reinstalled along with the new keys.
   • If you have forgotten the order of the keys, turn on your computer and look for an image of the keyboard on the Internet. In addition, in the computer settings you can find on-screen keyboard or a keyboard viewer.
   • Some people wash their keyboards dishwasher. Use this as a last resort unless recommended by the manufacturer.
   • If you have any questions about your keyboard or computer, contact a professional. He will inspect your keyboard and be able to clean it more thoroughly and safely to get it working again.

   Warnings

   • Washing your keyboard may damage it. This is especially dangerous with a laptop, as liquid cleaners can damage it.
   • When purchasing a keyboard or laptop, check out warranty obligations. Certain cleaning methods may void your warranty. To avoid this, follow the manufacturer's recommendations or contact a specialist.
   • Compressed air is toxic, so work in a ventilated area and do not inhale the contents of the compressed air canister.

Sometimes users encounter such a problem that part of the keyboard on their laptop does not work. In principle, it happens that the entire keyboard does not work at once, but then, most likely, it just needs to be replaced. But if only some of the buttons stop functioning, everything is somewhat more complicated.

We will consider everything that can be done in this case independently, without the involvement of specialists.

Simple ways to solve the problem

It is not always necessary to do something complicated in order to restore the functionality of a part of the keyboard. Often the problem is solved quite simply. So from the very beginning, do this:

1.Try pressing the Fn and Num Lock keys. It is possible that pressing one of them blocked some buttons on the keyboard.

2. Hold Fn and press Num Lock, then release both buttons. In some cases, this simple method allows you to get the keyboard fully operational.

3. Take a brush and go over all the buttons. It is quite possible that some dust has accumulated under one of the buttons. If possible, also take a vacuum cleaner. On the Internet you can find special vacuum cleaners for small keyboards.

Keyboard vacuum cleaner

4. Restart your computer. In some cases, there may be some minor bug in the system that prevents certain buttons from working.

In most cases, the problem will be minor and can be fixed with one of these steps. If nothing works, move on to the next step.

Fixing a software glitch

It is quite possible that the problem is the malfunction of some programs or services. To check this option and fix the problem, you need to do the following:

1. Boot from safe mode without drivers. To do this, restart your computer and immediately start pressing the F8 button. Select “Safe Mode” from the boot options.

Note: Depending on your system configuration, the boot mode selection button may differ. So try using all the buttons from F1 to F12 if pressing F8 does not help. As a result, a window similar to that shown in Figure 2 should appear.

Options for selecting system boot mode

2. Try to create some kind of document and use all the buttons on the keyboard. You need to check not only those buttons that previously refused to work, but also all the others! If this is really the case software glitch, kit broken keys may change with each new launch.

So, if all the buttons work well, then the problem is really in operating system. The most likely solution to the problem lies in updating the drivers. It's best to do this in a standard way:

• Open the “Start” menu (Windows), then “Control Panel”, find “Device Manager” there;

Device Manager in Control Panel

• open the “Keyboards” item;
• usually there is only one keyboard, click on it right click mouse and select “Update drivers...” (if there are several keyboards, which is very unlikely, do the same with all of them);
• select the item " Automatic search…»;
• wait until the drivers are found on the Internet, they will be installed automatically.

Updating drivers using the standard Windows method

You can also download and install the program DriverPack Solution. It allows you to scan your entire computer for the latest available drivers. If the keyboard has incorrect (roughly speaking, “broken”) or outdated drivers, you can easily replace them. The usage of this program is as follows:

• download the program (here is the link);
• install it and run it;
• An automatic scan will occur, after which just click on the “Update all” button.

DriverPack Solution Window

Scan the system with your antivirus and remove all detected viruses. You can also use for this special utilities, such as Kaspersky Virus Removal Tool or Malwarebytes Anti-Malware Free.

If updating and scanning drivers does not help, try rolling back the system to a time when everything worked well.

To do this you need to do this:

• open the “Start” menu, then “All Programs”, “Accessories”;
• after that, go to the “Utilities” section and click on “System Restore”;

System Restore item in the Start menu

• in the window that opens, click “Next”;
• then select the desired restore point, and here they are sorted by date and time (you need to choose the one that most accurately corresponds to the time when everything was fine);

Selecting a restore point for system rollback

• Click Next and then Finish.

In principle, you can reinstall drivers and roll back the system in cases where safe mode The keyboard also doesn't work properly. But in this case, the likelihood that it will help is very small. Most likely, the problem is mechanical, not software, and it needs to be solved by physical intervention in the computer device.

Fixing a physical glitch

In this case, you will have to disassemble the keyboard and see step by step what could have gone wrong. To do this, run the following actions(it is very important to adhere to the exact order in which all actions will be listed below):

1. Turn off the laptop and remove the battery.

2. Take a flat-blade screwdriver and carefully remove all the latches on the plate that holds the keyboard in place. If you don’t see any latches on your laptop, you should pick up the instructions and read what it says about the design of the keyboard and how it is removed. In any case, some kind of fastening mechanisms must be present.

The process of opening the keyboard plate latches

The keyboard plate is attached to the laptop itself using a cable. You will see it immediately.

3. So, if there is obvious damage on it, the cable should simply be removed and replaced with a new one. To do this, take an old cable, go to the nearest electronics store and buy the same one.

Keyboard cable

4. If the cable is not damaged, it still needs to be removed. Under no circumstances should you take the cable by the conductors! You can only grab those plastic parts that attach it to other parts of the laptop. For clarity, Figure 10 shows those parts that can be handled and those that cannot be handled. True, keyboards usually use slightly different cables.

5. There, under the keyboard plate, you can find the microcontroller. It's necessary dry and try to remove dust using a vacuum cleaner.

It is quite difficult to explain how to find this microcontroller. To put it simply, this is exactly the device to which the cable is attached. Just in case, when removing the keyboard, go through all the controllers you see. You won’t be able to do anything else on your own without special knowledge. Again, if you see obvious damage to the microcontroller, it is best to replace it.

Laptop with keyboard removed

6. If everything is fine with the cable, you will have to disconnect the keys and clean them. Usually the button can be removed in the standard way - pry it off with the same flat-head screwdriver. Start with the problem buttons. If you see damage underneath, replace the elements that secure the button to the laptop.

The process of removing buttons from the keyboard

7. Try using the keyboard again.

If the problem persists, remove all the buttons and remove the aluminum plate that is located under them. Usually it also has special fastenings that can be removed quite easily. But underneath it is hidden a polyethylene board with traces drawn on it.

Inspect it for obvious damage - if there is any, there are two options: draw new paths or buy new board. In any case, go over the board with a vacuum cleaner.

To check the integrity of the tracks, use a tester.

Checking the integrity of tracks on the keyboard board with a tester

To draw the tracks, use a car rear window heating filament repair kit (that’s what it’s called).

If all else fails, your best bet is to have your computer repaired.

The video below clearly shows the process of disassembling a laptop keyboard.

Part of the keyboard on a laptop does not work: what to do and how to fix it - a detailed guide

If you spilled a drink on your keyboard and it stopped working, but you don’t want to buy a new one or you can’t, don’t worry, cleaning it isn’t that difficult. All you need is patience and about two hours of your time. If your keyboard has dried out and started working on its own, don’t worry, you still need to clean it, otherwise the problem will return to you later, but cleaning will not help.

Well, if you still haven’t spilled anything, don’t despair, this can happen to anyone! My laptop, for example, was very high and far away in relation to the drink. However, you never know in advance what flight path the spilled tea will take.

First of all, it should be noted that liquids pose a danger to the entire system. Even if everything works now, in a few months your laptop may go to the landfill. In the event of an incident, it is advisable to immediately turn off the power to the laptop by removing the charger and battery (yes, the liquid will not wait for the programs to complete). Then just as quickly turn it over with the flooded side down and let the liquid drain. Then completely unscrew and assess the damage. Do not connect the power if there is liquid inside or its remains in the form of sweet syrup. In the case of pure (distilled?) water, you need to wait a day for all the liquid to evaporate. In the case of tea/coffee and other drinks, the insides must be cleaned, otherwise there will be a short circuit on the board, oxidation, and this will easily kill your laptop. In this article I will not describe how to rinse motherboard. We will assume that you, like me, spun up the laptop and discovered that you were wildly lucky, because... Only the keyboard was flooded.

The experimental sample is my damaged Eee PC 901. Naturally, yours may have some differences, but in general the procedure is identical on most models. Sorry for the quality of the photo, I shot with what was at hand. Well, I hope everyone understands that they follow my advice at their own peril and risk.

We remove the keyboard. For me, it is secured with three latches on top, which need to be carefully pressed one at a time, while pulling the keyboard up. As soon as you free the keyboard, do not rush to happily pull it out: you need to disconnect the cable. In the photo you can see it at the bottom left.

No, at the very bottom - my legs accidentally got into the frame, and the train was right under the keyboard. The cable doesn't just pull out. It is secured with clips on the sides. First, carefully pull them up along the train. A small screwdriver will work for this (this will also come in handy later). Then the cable can be easily removed. I repeat: EASY! Be careful not to scratch the tracks on the motherboard with a screwdriver.

So, we have a disconnected keyboard. We examine the space under it for something tasty. We are especially interested in the liquid or its characteristic traces, identified by the color of the original drink.

If there is at least some suspicion that the liquid could penetrate further, then it is better to continue disassembly. You can find instructions for your laptop model online. If there are no traces of liquid under the keyboard, and you are so lazy to disassemble further that you are absolutely sure that only the keyboard was damaged, then we leave it on your conscience.

On the Internet you can often find advice to rinse the keyboard in warm water. I would advise you to take this matter more seriously and rinse the entire laptop at once. But... I won't. Let's take a look inside to realize the ineffectiveness and danger of this method.

First you need to remove all the buttons. Each button consists of an upper platform and an elevator - a miniature structure under the platform that ensures the mobility of the button. I found advice to first remove the platforms, prying them up in a strictly defined place, and then remove the elevators. This method seemed weird to me, because I wasn’t sure whether the button would come off before the elevator broke down. In addition, I still didn’t understand where to put the screwdriver in order to safely unhook the button. Finally, when I turned the keyboard over, I realized that at least in my model you can unhook the buttons immediately with the elevators. This simplifies everything.

The photo shows (badly, but clearly) that there are three “holes” for each button. In your case there may be four. Well, if not at all, then you will have to first remove the sites separately. On one side, the elevator is fixed with a “hook”, on the other - with two latches. We select the most unnecessary button on the keyboard (e?), and try using a screwdriver to first disconnect the latches, pressing down and to the side, then the hook. Broke? It’s okay, don’t mind, you still have so many of them!

The detachable buttons can be neatly folded in the same order for easier assembly later. Attention! Small children really like these buttons, keep them away from each other.

It is also advisable to photograph or scan/xerify it in advance.

After all the buttons are removed, remove the top rubber gasket.

This thing acts as springs, and usually does not serve as contacts (unlike remote controls, if anyone has taken it apart). But for hygienic reasons, it’s still worth washing it.

Below it we see this picture.

At first glance it may seem scary, but when we break everything down into layers, it will become clearer.

The heart of the keyboard is three layers of films with tracks and contacts. The upper and lower ones are formed by folding a solid film in half, with tracks and contacts inward.

The middle layer is insulating, has no tracks, but has holes through which the contacts of the upper and lower layers come into contact when you press the buttons.

These three layers pose a problem, because liquid willingly flows there, carrying sugar and other substances dissolved in it. The water will dry out, but the pollution will remain. It will be quite difficult, if not impossible, to wash an unassembled keyboard in water. Therefore, the layers need to be separated. This is the hardest part.

The film layers are glued together. I can see blue glue: a solid strip along the edge, and dots throughout the entire area.

I was able to easily separate one layer, starting from the edge. Then, by pulling the top layer up by the edge and holding the bottom one at the base of the keyboard, I separated it completely. The second one did not want to give in. It turned out to “tear” the edge with a screwdriver through the hole in the film. Further - as with the first. If the layer comes off poorly, or does not come off at all, you can try heating it with a hairdryer. Be careful not to tear the tracks. And be careful with the hairdryer too. Keep the hairdryer at a sufficient distance, and if such a function is provided, adjust the temperature so that the air does not burn your hands. Otherwise you might end up melting something.

The bottom layer is glued to the base of the keyboard along with the cable, so I did not separate it so as not to damage the connection. But in general this is not necessary.

Now each layer needs to be carefully cleaned, paying special attention to the contacts, tracks and spaces between tracks. Then we dry everything. A hairdryer will again help us speed up the process. Make sure everything is really dry and clean. You probably won't want to take it apart a second time.

Added:
Here I would like to quote very helpful comments from user Hayz about what to wash with. I washed it with water, because I couldn’t find any sane explanations at that time. It helped me, but I don’t know for how long.

I strongly do not recommend using water to wash keyboard contacts. Otherwise, subsequent oxidation of these contacts is possible, and, as a result, everything will have to be changed. It is better to do this with alcohol, and at least 96% is highly desirable. And the sooner after the “flooding”, the better. The essence of alcohol is that it collects water that is in the pores and quickly evaporates. It is clear that in this case the amount of alcohol should be much greater than the water in the solution. Otherwise, there will be no effect of moisture collection. Those. vodka 40% will not work. Cologne "Triple" 75% is better, but not good.

Tap water is not that pure - there are a lot of all sorts of impurities and salts that act as a catalyst for corrosion and begin to destroy the metal. There are much fewer such salts in atmospheric air, so corrosion takes much longer to occur.

Regarding alcohol, everything is not entirely clear. Alcohol and alcohol are different, and not everyone can be suitable for these purposes. It is better to use traditional ethyl alcohol (ethanol). Isopropyl alcohol has sometimes erased people's contacts and letters on their keyboards. And if you rinse with water, then be sure to use distilled water. From my point of view this is the safest option. Of course, all this does not apply to the rubber gasket and other non-conductive elements. They can also be washed under the tap. Overall, this issue is still not clear enough, and it would be good to hear the opinion of a competent person.

It is also worth inspecting the paths for damage. It could happen if a lot of time has passed since the flooding, as well as if the layers were inaccurately separated. According to victims, the tracks can oxidize and crumble, crack or peel. The tracks can be restored using conductive varnish. They say this one is sold inexpensively in car dealerships and is intended for restoring rear window heating filaments. They need to carefully draw the damaged parts of the tracks. At the same time, make sure that thin threads of varnish do not form a short circuit between the tracks.

Once we've finished cleaning and repairing, we put everything back in reverse order. Carefully and evenly connect the layers of film, put an elastic band on top, and secure everything with corner buttons so that nothing moves out.

The button is placed like this: attach the hook, gently press on the pad from the side of the latches, click - and you're done! To make sure that everything is done correctly, we install the keyboard in place, fixing the cable, turn on the laptop and check the operation of the buttons. Everything works, nothing fails? Turn off the power again, remove the keyboard and install the remaining buttons in random order. There are approximately 80-100 pieces in total. Not as much as it might seem.

Before putting the keyboard back in place, carefully inspect the buttons to make sure they are all aligned. My Enter is crooked, and some other buttons are dancing (which, in general, is not critical). But I don’t want to turn off the laptop. That's how we live.

Repairing a flooded keyboard

Remember, the most dangerous enemy of your laptop is liquids spilled on the keyboard. Coffee, juice, Pepsi kill buttons with their taste. The keys of a flooded keyboard, having drunk sweet water, are hard to press, jam, and stick. Unpleasant? Then we go to you! If you delay, the keyboard will have to be replaced. The keyboard is especially well killed by Coca-Cola and Pepsi - these are the leaders in the corrosive ability of conductive paths! Oh, I forgot about beer, wine and puppy urine :). But I don’t have a dog yet (I hope I never will).

So in my unintentional experiment asus laptop eee-pc 901 reacted with Tonus juice “Apple with pulp” (without added sugar). What exactly this juice contains in 100% quantities could not be determined as a result of the reaction. However, the keyboard was flooded. Description of the experiment: as a result of inappropriate tremor of the hands, the juice flew past the glass and splashed into the area Enter keys. Immediately after realizing the gravity of this event, the laptop was turned upside down, but this changed little of the consequences. Without thinking twice, I decided to disassemble the keyboard and remove the remaining juice! On regular laptops, the keyboard mounting screws are located at the bottom of the case. I turned over my eee-pc 901, but I couldn't find any screws with a keyboard icon. “An unusual laptop,” I thought. Taking a closer look at the keyboard itself, I noticed that on the front part, in the area function keys F1, F6 and F12 have latches that hold it.

I pressed three little white buttons in succession and the panel with the buttons easily came off. To avoid damaging the cable during manipulations, I also unfastened it. To do this, use a thin object to push back the latches on each side of the connector. So, the keyboard has been removed.

As it turned out later, removing the keyboard is the easiest thing in this rescue operation. Trying to remove the buttons, I broke two fasteners before I understood the mechanism for attaching and removing the buttons. However, the functioning of the broken buttons itself was not affected by this. Now, after a while, it’s even difficult to determine which of them were broken. For those who still want to remove the buttons, I’ll tell you. On the back of the panel with buttons there are three holes for each key. It is necessary to press with a sharp object (a blunt awl, for example) from the outer sides sequentially on the plastic fasteners in the holes located nearby.

At the same time, the buttons move away with a quiet click. They do not depart to another world, but separate with the hope of further strengthening in their rightful place. Having separated the two buttons, I suddenly remembered that it would be nice to photograph the position of the keys so as not to rack my brains about which key has which place. After disassembling the keyboard, one thing became clear - it is disposable. Disposable - somewhere in Japan or Germany, but not in Russia. Removing the keys revealed numerous transparent films.

Under the films there is a tin substrate. Traces of the evil reagent - sour apple juice - were already visible on the substrate. Here it is, a keyboard covered in juice...

In the operation to neutralize the latter, cotton swabs for children's ears, alcohol and patience were used. Of course, the lint from the sticks is our evil enemy, but there was no other material at hand. And so, while everyone was sleeping, I started cleaning up. Having cleaned the tin layer, I suddenly noticed that juicy (it would be more accurate to say, juice) stains already existed between transparent layers films with contacts. I had to separate the layers. There were four of them.

Each of the layers was neutralized with natural real alcohol, brought specially for such operations from abroad. After this manipulation, the keyboard was assembled in reverse order. Yes, I had to tinker with the keys again before I learned how to put them in place. I'll tell you for those interested. Each key has three mounts. First we put on the mount that stands alone. After the fastener is put on, gently press the button and the key sits in its place. So, the keyboard is assembled. We connect it to the cable. We check the functionality of each of the keys. If there are problems, I'm afraid that you will have to remove all the keys again and repeat the operation.

Therefore, I urge you to immediately do disinfection efficiently the first time. In order to eliminate the consequences of a flooded keyboard. I performed this operation properly and did not have to do the job twice. We turn on the laptop - everything is normal. By the way, I connected the keyboard directly while the laptop was running. The next morning, a couple of keys were still somehow hard to press. It turned out that under the keys themselves, under the plastic, there were also juice residues. I removed the problematic keys and washed them under running water and dried them. If your case is fatal for the keyboard, then this can also be corrected on your own.

Take care of your Klava.

Some advice from victims:

The following steps must be taken immediately.

1. Disconnect the laptop from the network (unplug Charger from laptop)

2. Remove battery from laptop

3. Wipe off any remaining liquid with a dry paper towel or rag.

All these actions must be performed immediately after water gets on the laptop, without waiting for the computer to shut down normally.

How to remove the keyboard?

• First, find two screws labeled “KBD” (keyboard/keyboard) on the bottom of the laptop.
• Unscrew the screws and turn the laptop over to its normal position.
• Now look carefully at the edge of the keyboard closest to you. Approximately the gap between the spacebar on the keyboard and the laptop.
• Along the entire length of the keyboard you will see three small latches. These latches must be carefully pushed aside to release the keyboard.

ATTENTION! After disconnecting the keyboard, do not pull it sharply towards yourself or try to move it away. It is connected to the laptop with a thin and short cable. Disconnect the cable and go into battle.

You can try just drying it:

• It is advisable to first rinse it in distilled water. If tea, coffee, beer, juice is spilled on the keyboard, it is MANDATORY to wash it in distilled water!

• There is a high probability that after drying it will be fully functional. For drying, you can use, for example, an electric oven. Set the temperature to 70 degrees and dry the keyboard in it for 4 hours or more. You should not set the temperature higher, because... The buttons may melt.

• You can simply put it in the sun for at least 1 day, or better yet, two. It's better to spend more time drying it than to buy a new keyboard later.

• After all, if you don’t dry the keyboard completely, moisture will remain between the films and the tracks will gradually be eaten away by corrosion.

• After that, try connecting the keyboard and check its functionality in text editor. If the keys print other letters or the letters print themselves, it means the keyboard has not dried out enough and there is moisture left between the films with sprayed tracks. Repeat the drying process.

• If the keys on the contrary do not work, it means contact areas dielectric or corrosion present. Try rinsing again more thoroughly and drying for a longer time.

Buttons sometimes stick not only on new MacBooks, but also on old ones. Usually it is recommended to disassemble the keyboard for cleaning, but in practice this only leads to - Mikk has already proven this.

We'll tell you how no vandalism Clean the keyboard using a couple of proven methods if the buttons on it are already sticking or are just being assembled.

Five minutes once a week and the buttons on my MacBook Pro 2017 works like clockwork. Yours will be no worse.

Why do the keys on a MacBook occasionally stick?

The keys begin to stick only because foreign particles get under them. There are no other options, and buttons even with a broken mechanism do not behave this way.

If something gets under the button, it prevents it from being pressed, and it seems to you that it is simply stuck to the base. That's why they say the key is “stuck.”

They began actively writing about the problem in 2015. The world saw a 12-inch MacBook with a butterfly keyboard. New mechanism It turned out to be much smaller in size, so cleanliness turned out to be more critical for it than for the usual “Scissors”.

In 2017, “Butterfly” was updated to the 2nd generation, the problem began to appear less frequently, but remained.

However, the services say that they are regularly contacted not only by owners of new MacBooks, but also by old ones. Why?

Residues of food and dust. Yes, these are the most frequent guests of your keyboard, who happily find hidden places under the keys and prevent them from being pressed.

If you eat near a MacBook, you have already encountered or will encounter this problem in the near future.

If you don't eat near your MacBook, dust still falls on it, so you won't be able to avoid getting stuck.

Pieces of skin and sweat. Microscopic parts of your body, to a lesser extent, can also cause sticky keys.

To minimize the effect, do not forget to maintain hygiene - just wash your hands with soap and water more often.

Tea and water with sugar. Liquids with sugar are critical for the keyboard. IN in this case It will not be possible to completely get rid of sticking even after cleaning.

Even before the New Year, I spilled tea with sugar on the keyboard of my MacBook - there was minimal liquid, it was quickly removed at the nearest service center, but I was not able to save the keyboard.

The only correct solution was to replace the keyboard. That's what I did.

Apple has not officially acknowledged the sticking problem. MacBook keys. And it was pointless to do this, because this can be avoided with banal accuracy.

But a large stream of criticism against the company forced it to update the Butterfly, which became more practical - this is a step towards users.

And last year, the manufacturer released a guide on cleaning the keyboard from dirt using compressed air.

Yes, Apple suggests simply blowing out food debris and other foreign objects from under the keys with a special balloon.

By the way, you can easily find one like this in any store. modern electronics or order online. The asking price is 200-400 rubles.

Step 1. Hold your MacBook so that its keyboard is at a 75-degree angle to you—no need to place it vertically.

Step 2. Blow the entire keyboard or just the most problematic keys, first from left to right, and then from right to left.

Step 3. Place your MacBook on its right side and do the same.

Step 4. Place your MacBook on its left side and repeat the procedure.

Please note that when using a compressed air cylinder, a small amount of liquid may be released from it. It's harmless, just wipe it off your keyboard with a tissue.

Our drugstore method for cleaning your MacBook keyboard

You can use more than just compressed air to remove dirt from your MacBook keyboard. You can simply blow on the buttons with your mouth, but this is not as effective.

It is better to use a “Pear” type enema-syringe from the nearest pharmacy for purging. Don't laugh - the method works quite well. Roma Yuriev wore it a couple of years ago.

Blow air out of the device so that it fits under the keys. The faster you compress the rubber part of the device, the more efficient the process will be.

Which syringe to choose? I took the smallest version with a plastic tip to prevent blockages, which I do once a week.

If the blockage is serious, it is better to pay attention to the larger option. With it it will be easier to create a powerful stream of air.

How to avoid problems with keyboard sticking 100%

To protect the keyboard from dirt and further sticking, you can use special covers, which are abundant on AliExpress for every taste.

But working with them on a MacBook is terribly inconvenient. I don't recommend this option.

It’s better to thoroughly blow off dust from the laptop buttons with a syringe or compressed air from a cylinder at least once every one to two weeks. Then you are unlikely to encounter sticking.

And if you can’t handle the problem yourself, go to service. Do not try to disassemble the keyboard - do not repeat the mistakes of others.
