How to remove the top cover of a laptop. Unscrew the remaining screws and disconnect the connectors, remove the motherboard
Greetings, dear friends, readers, subscribers, acquaintances and other individuals who happened to read this material. I am glad to welcome you again to the pages of the project and his website" Notes from Sys.Admin"I think that many people remember various articles about all sorts of computer hardware and internals (namely, about assembly, selection, configuration, etc.), as well as
Today we will continue this interesting direction and let's talk about such a thing as disassembling a car down to the cogs in order to bring it back to life and expel all dirt from it (namely, the aforementioned dust). How is it? Yes, it’s simple: laptops are the most harmful devices in terms of assembly and disassembly, and at the same time, they quickly become clogged with dust (wherever they are carried and placed) because, in fact, of their purpose.
Moreover, laptops tend to get noticeably warm due to weak cooling systems and poor air circulation, which leads to the most tragic consequences, ranging from slowdowns and ending with the skates being thrown off, usually immediately by the laptop itself (rarely only some specific detail). In general, cleaning must be carried out, albeit less frequently than with a regular desktop computer.
However, aside from the lyrics. Go.
Preface or what we have and why we need it
It just so happened that I had a need to clean another laptop, and therefore it was decided to finally write an article, so to speak, along the way and without delay. Therefore, I armed myself with a camera and, using personal example, I will tell you what’s what, along the way making comments about what is necessary, how to do it correctly and what mistakes there are.
Attention! Before you begin, read the entire material several times very carefully. If you decide to disassemble a laptop of another model, then look for the service instructions (more on this at the end of the article) for your model and carefully study it as well.
Attention! When disassembling a laptop, you are in 99 In % of cases, you lose the warranty from the manufacturer and store.
Attention! The author removes himself all responsibility for any Your actions and the consequences they may lead to. When disassembling or assembling a laptop, mentioned or not mentioned in this article, you act at your own peril and risk. Final result depends on you and only you. If you are not confident in your own abilities, then do not start or stop at the moment when it seems to you that further actions may lead to breakdown.
What we have:
- Laptop HP tm-2100 with a touch (and rotating) screen that lasted about 5 years without hardware maintenance (i.e., not disassembled or cleaned). Later 5 years old, it began to buzz very loudly (it works almost 100% and copes poorly with the task), warms up, turns on on its own (doesn’t really go into sleep or hibernation), slows down even when opening pages in the browser, and so on and so forth.
What they were doing:
- Software cleaning, . Does not help. The problem is clearly a hardware issue.
What you decided to do:
- Disassemble, clean, change thermal paste and, if possible, the cooling system.
Actually, I’m writing this article using this laptop as an example, because it’s quite tricky to disassemble if you don’t know the nuances. Therefore, I decided to analyze the conditionally complex option, so that it would be easier for you to deal with less complex solutions later.
Now we can get down to business.
We disassemble and clean the laptop in order to bring it back to life
We will need:
Disassembly and cleaning process:
Before we begin, one more comment for beginners. Take pictures for yourself of the ENTIRE disassembly process. This will help you put your laptop back together. Believe my experience - this is VITALLY necessary. No instruction will help you at first as much as your own photographs. Assembling is often more difficult than disassembling.
- We take the laptop and put it on workplace, where we will analyze it:
- Turn off naturally ( Start - Run - Shut down):
- After waiting for it to turn off, close the screen and turn the laptop upside down:
- The first thing you need to do after turning it off is to remove the battery in order to completely cut off the power to the laptop. To do this, you need to pull the latch with some force in the direction indicated by the arrow and pull out the battery:
- Having done this, we need to extract HDD And RAM. To do this, there are special bolts on the back cover, which, as a rule, are signed or marked with pictures:
What's important here: Firstly, often, if the assembly is good and the company is adequate, then the bolts Not unscrew all the way. More precisely, they unscrew completely from the groove, but you won’t be able to get them out with a screwdriver or shake them out, because... they are secured with a ring that prevents them from falling out, which is great, because the bolts are small and it’s quite easy to lose them. However, due to inexperience, you risk, at best, sitting for an hour or two, thinking that the bolts are turning in the groove, although this is not the case. Therefore, there is this warning from me, because once upon a time I myself fell for this “trick” :)
Secondly, one pair of bolts does not always hold one cover. It happens that, as in in this case, the second pair of bolts from another cover (for example, RAM) is involved in clamping the first cover (from hard drive), and then it turns out that you need to unscrew all the bolts and remove everything at once, and not partially. This does not happen on all laptops, but quite often. - Next we need to remove the hard drive. This is done first by moving in the direction from the connector (see red arrows), and then by pulling the disk up from the laptop:
There is nothing difficult about this, but be sure to exercise caution and accuracy. Just in case, as they say. Don't pull or yank if it doesn't work. It is most important. It’s better to measure ten times.. In short, everyone knows this saying :) - Next we remove the RAM. To do this, you need to pull the side white (in this case) pressing clamps and move them apart at the same time (see red arrows):
After which the memory bar, in most cases, will rise up and it can be removed manually without any obstacles. - After removing the memory sticks, we need to remove the module WiFi. This is done as follows:
First, we pull out the contacts (wiring with roundels) from the grooves of the board WiFi(blue arrows in the photo), and then unscrew the bolts (red arrows) and remove the board, putting it aside. - Before continuing, I recommend that you take the leaflet mentioned above A4 and pen(s) or marker(s)/felt-tip pen(s), as well as a camera or camera on the same mobile phone. For what? Then, so as not to get completely confused in further steps and during assembly not to get lost in the number of screws, bolts and other things.
What's the point? The fact that it would seem that we are all so smart, we remember and know everything, our memory is perfect and all that stuff, but... Believe me personal experience, when assembling it turns out that there is nothing of the kind. I assured myself many dozens of times that everything was sensory obvious and it was impossible to forget where this screw and that bolt came from. Yeah, yeah :) In fact, it turns out that the bolts are different, located in the most unusual places and for various details, there are really a lot of them, but memory is not the smartest thing and tends to be harmful. Seriously. In short, everyone who is naively confident in their abilities is right on 100% like superman, I’m very happy for you, really. For the rest.. Distribute all the screws that can be unscrewed on paper as they belong to something and circle them with a signature where they come from. If the circles are multi-colored - generally ideal. Once upon a time, in my youth, I even drew a sketch of the motherboard circuit, saying where it came from - what, but these are already unnecessary details. And, yes.. Try to photograph every step, so that even if the diagram fails you, then from the photograph you will know exactly what is coming from and why. Believe me, this will come in handy when assembling. - The next step is responsible for unscrewing the bolts, but before that, let's remove the battery from the motherboard (by simply pulling it out of the connector):
- Next, we unscrew all the bolts available to us. That's all (the photo below is just an example of legs, deep grooves and other things):
Keep in mind that Very often the bolts are hidden under the legs (you have to tear them off and then re-glue them) or under labels, be it labels with the name of the laptop model or serial number Windows. Usually they can be easily felt by hand, but not always. One way or another, keep in mind that it is better to search than to break. I repeat that by disassembling the laptop and, even more so, violating the integrity of the labels, you lose the warranty. - After making sure that we have unscrewed all the bolts, we turn the laptop over to its normal position, i.e. "belly" down. Next, you need to be careful, because...
Attention! Further actions disassembling a laptop are often associated with breakdowns due to negligence. Be careful and attentive.
The thing is. IN 95% cases, after you have unscrewed everything, you need to open the surface of the case, and it is secured with plastic clips and latches, which tend to break off, resist in every possible way, and so on and so forth. In my case, I had to pry the surface with two screwdrivers and very carefully pull it with my fingers so that the lid opens:
Again, don't pull too hard if something doesn't fit or open. Often you either forgot to unscrew the bolt, or you press and pull in the wrong place. Be careful, feel where it opens, where it doesn’t and why. Otherwise, by getting impudent and tugging at the plastic, you risk damaging the case. Plus, you don’t have to immediately drag everything up too much. Be patient. Under the cover, as you can see in the photo above, a touchpad (a surface that replaces a mouse) and a keyboard are usually attached by a cable, and they must be removed as calmly and adequately as possible. - Further, for understanding, just an exploded view photo, i.e. without the top cover + the same cables:
- Then we need to pull out everything that is stuck. Here, too, you need to be careful, take pictures of every step and remember what comes from.
We turn off the on/off switch, i.e. laptop power button:
Something related to cooling in some way:
Two cables from the monitor (it is very important not to forget to pull it out, because then you need to remove the monitor):
Other things to suit your taste (in my case it’s a connector for a stylus, but yours can have whatever you want connected to the motherboard):
- When all possible cables have been removed, then we are, in fact, interested in removing the monitor. IN regular laptops this process occurs in a variety of ways, but if you have already turned it off and all the false panels have been removed, then all that remains is to unscrew it. In my case, the process looks like this:
Three bolts on one side, three on the other... And the monitor is removed:
- Next we have the bare board, which is still screwed to one of the remaining parts of the case:
We actually unscrew the bolts and carefully (as a rule, it is fixed) pull it out motherboard. Keep in mind that you may need to unscrew something else, depending on your laptop model. Look carefully for bolts and fasteners before trying as hard as you can. - Now we finally get to the cooling system by turning the board over:
As a rule, it consists of a heat pipe that transfers heat to a radiator blown by a fan. The tube is strung on plates responsible for heat transfer and pressing function. In the photo above you can see an interesting point - on the chipset on the left there are two bolts missing, which are listed in the service manual, but were not screwed in by good assemblers (they steal, save, something else?). Such is the romance. - We are interested in cleaning this entire system. First you need to remove the fan, which is easy, because you just need to unscrew a few bolts, which you can easily find:
- Next, the fastening of the heat pipe and its plates is disassembled:
- Well, then it’s a matter of small things.
- First, remove any dust you find from the radiator and fan.
- Secondly, you need to remove the remnants of the old thermal paste with a napkin. If instead of thermal paste, what I call a pad of pseudo-thermal paste is used and it is not damaged, then it is not necessary to remove it (the pad). If damaged, it is better to replace it with a layer of good thermal paste. In the photo above you can see that one pad is damaged, one is intact, and in the very middle there is just a print of thermal paste. In this case, I removed everything unnecessary (i.e. the pillow itself) on the left and in the very middle, and left everything on the right as is.
- Thirdly, all that remains is to apply thermal paste to the cleaned surfaces (there is an article on how to do this here - " ").
- Well... The most important thing is to put everything back together. This is done in reverse order, exactly the opposite.
In a nutshell, something like this.
Afterword
Another important point, which I simply have to mention. There is such a thing as service manuals. Essentially, these are instructions for service centers in which (instructions), in fact, it is described how to disassemble and assemble the whole thing (with pictures and so on). You can find it in (most likely) or Yandex(not sure here) on request" Service Manual + n", Where n- this is the name + company of your laptop model. In most cases, if you wish, you can download either this very manual (though, as a rule, on English language), or find instructions made by someone (like, for example, what you just read on HP tm-2100). I strongly recommend searching and trying, just in case, as they say. If suddenly your specific model is not available, then look for related ones - often the disassembly process is identical.
Well, as for the rest... I tried to simplify the text of the material as much as possible, simultaneously making comments on the most key points. If anyone has anything to add, correct, etc., I’m always glad to see you in the comments. As always, I welcome questions, thoughts, thanks and everything else.
Stay with the project. You are always welcome here.
Overheat- one of the three most common “ordinary” problems of all laptops. It occurs due to the fact that the cooling system of the laptop becomes clogged with dust over time, preventing hot air from escaping from the case.
If your laptop, some time after turning it on, begins to get very hot, make noise, slow down, or even turn off abruptly - all these are signs that you urgently need to clean your laptop from dust and change thermal paste.
You can contact Computer service, but you can try to do prevention on one's own.
All you need for this is a couple of simple, available tools, and a certain amount of accuracy and attentiveness. Well, some kind of algorithm for disassembling a laptop, which I will explain to you in this article on my computer blog.
Overheating begins to appear after 1-5 years of using a laptop, depending on the model and conditions of use. But, sooner or later, it will come, because over time, a layer of cosmic dust slowly but surely accumulates on the laptop fan.
I'll try to make my own subjective TOP Hottest laptop models:
- HP, especially models Dv6,G7
- ASUS
- ACER
- SONY
- LENOVO
- SAMSUNG
- DELL
- TOSHIBA
I have already written an article about that, as well as how fast and free.
We will assume that you have already An overheating problem was diagnosed. That is, they did a temperature test and found out that under load the temperature of the processor and video card of your laptop rises to 90 degrees or more.
But this was all theory and diagnostics. Now we will get down to practice and actual repairs - disassembling and cleaning the laptop from dust with your own hands.
Disassembling a laptop- not like that simple task, as it might seem at first glance to a person who has never “opened” his laptop.
If in most system units, to access the “internals” you need to unscrew 2 screws and slide the lid, then in laptops everything is much more complicated.
There are many laptop manufacturers, each with hundreds of different models, and they are all understood differently. Somewhere you just need to remove the bottom cover. For example, this is exactly the case with . And somewhere, in order to get to the motherboard and remove the cooling system for cleaning and replacing thermal paste, you need to completely disassemble the laptop case, “down to the bolt.”
But general algorithm for disassembling a laptop, as a rule, is always the same. In short, you need to unscrew all the screws, disconnect all the cables, connectors, and open all the latches.
How to independently disassemble any laptop and clean it from dust - universal instructions.
Below I have drawn a laptop device with all the details indicated, so that it would be easier for you to navigate when reading this article.
1. Disconnect the battery
First of all, always disconnect the battery. Disassembling a laptop under voltage can ruin your laptop by accidentally dropping a bolt onto the motherboard. Therefore, the first thing we do is take it out.
On some laptops, the battery is located inside the case, such as. Before turning it off, be doubly careful not to short-circuit anything.
2. Unscrew all visible bolts on the bottom.
Pay attention to their length and thickness. If they are the same, you don’t have to worry. If some come across longer/shorter, we remember/sketch where they were twisted.
3. Remove all the caps on the bottom, and unscrew all the bolts under them
We remove all the small covers on the bottom of the laptop (RAM, hard drive), unscrew all the screws, put them in the next pile. Disconnect all connectors, if any.
You may not have such caps; the bottom of the body may be solid. Don't be alarmed - go to step 5.
4. Disconnect the Wi-Fi module, hard drive, RAM, DVD.
For Wi-Fi shutdown module, first remove the 2 antennas from it by pulling them perpendicular to the module. Remember where it was. Then unscrew the bolt securing it and pull the module out of the slot.
Having unscrewed the hard drive, we look at how it is connected. You can remove it by either moving it away from the connector, or by disconnecting the flexible wiring by pulling it.
As a rule, it is not necessary to remove RAM. But you can remove it and clean its contacts with an eraser.
At this stage, most often you can remove the DVD-ROM by slowly pulling on it.
The removable keyboard is easy to distinguish - it looks like a “block” keyboard, i.e. does not form one whole with the rest of the body.
If you have made sure that your keyboard is built into top part laptop case (Sony, ASUS 500 series) - go to step 8.
6. If the keyboard is removable, remove it.
Don't forget that there is a connection from the keyboard to the laptop motherboard. plume, so after removing it, do not rush to pull it, but first lift and disconnect this cable.
More often for removing the keyboard you need to carefully pry it off with a pick or spatula, and open all the latches around the perimeter.
It happens that before this you need to first remove panel above or under the keyboard.
On some laptops there may be another one waiting for you an unpleasant surprise- additional keyboard held on by glue. In this case, carefully pry it up with a ruler/spatula/screwdriver, and, gradually lifting it, peel it off.
7. Unscrew all visible bolts under the keyboard, remove all cables and connectors
There are several main types of loops. They all unfasten differently. Some rise, some lift, some stretch.
I will try to systematize them in one of the following articles on the site.
Sometimes at this point you will need to pull long wires from the wi-fi adapter through the case.
8. Carefully “open” the laptop from the side around the perimeter and remove the top cover
For me, the most convenient way to do this is to use a guitar pick, preferably thicker - 0.8-1 mm.
Also, sometimes a spatula helps:
Having walked around the perimeter with a pick and unclipped all the latches, we carefully try to lift the lid. If it doesn’t work, check again that all the screws are unscrewed. If it still doesn’t work, check it again.
No need to use force! And an unscrewed screw often turns out to be imperceptibly recessed into the case, or hidden under a rubber stand at the bottom of the laptop.
The motherboard can be attached either to the bottom of the laptop case (most often) or to the top (this is what they do Sony Vaio). Be careful and take your time.
9. Unscrew the remaining screws and disconnect the connectors, remove the motherboard
We look at which cables go to the motherboard and pull them all out.
Sometimes, in order to remove the motherboard, you have to completely unscrew and remove the top part of the laptop with the screen.
10. Remove the cooling system from the board
The screws on the radiator are usually marked with numbers - we unscrew and tighten them in the order of these numbers, so as not to accidentally damage the chip by misalignment.
We work very carefully here - a screwdriver can easily slip and knock down some element on the motherboard.
Having unscrewed all the bolts, carefully pry up the cooling system; if it doesn’t work, you can turn it a little in its plane. We try not to tear the thermal rubber bands, if any.
11. Disassemble and clean the laptop fan from dust
Actually this is the most main stage laptop disassembly. Right now, in fact, “cleaning the laptop from dust” will take place.
Usually, to disassemble the cooling system, you need to unscrew several small screws on it, and tear off a piece of fabric/adhesive tape, “turning” the fan outward.
We see dust accumulated on the radiator grille - remove it with a brush and blow it out. Congratulations! The laptop has been cleaned) But that's not all.
12. Remove the old one and apply new thermal paste
We remove the old thermal paste from the places where it was, on the chips on the motherboard, and on the cooling system. You can remove thermal paste with a dry cloth and cotton swabs. If you have them, you can soak them in alcohol and take them internally at the same time :)
Often, instead of thermal paste, you can see thermal pads. It is very desirable if they remain intact - it is quite difficult to find them on sale, only to order. If this rubber band is severely torn, most likely it is already “non-working”, you will have to look for it and change it. Or spread a layer of thermal paste. But I don't recommend doing this. Change it! Usually thermal pads are placed on elements that do not have a temperature sensor and protection against overheating, and your laptop may suddenly “die”, while showing normal temperature on the processor and video card.
Apply new thermal paste. How to smear? As thin a layer as possible. Thermal paste is needed not to cover the entire surface of the chip, but to smooth out surface irregularities.
I will write about various thermal pastes short review in one of the following articles on the site.
And in this video On my YouTube channel you can see how to apply thermal paste using the Pavillion G6 laptop as an example.
13. Reassemble in reverse order.
We assemble it in the same way as we disassembled it, carefully checking at each stage that all connectors are in their sockets. In theory, there should be no “extra, empty” ones (but there may be some).
It is advisable that there are no extra bolts left, but if there are some left, don’t worry! 😉 The main thing is that the bolts in the hinge area are screwed in - otherwise the laptop will fall apart over time.
14. We do a temperature test - rejoice! 🙂
Thermal paste needs some time to spread evenly under the pressure of the plate. So its maximum effectiveness is achieved after a couple of days of using the laptop.
Tips and tricks when disassembling a laptop yourself
- Collect screws from each stage of disassembly in separate piles - this way you won’t be mistaken about which screw comes from, and you won’t have any left over.
- Use the Internet - for almost every, or similar, laptop model there is detailed photos and video instructions for disassembly!
- Don’t use force - if something “doesn’t work”, double-check 10 times to make sure you’ve unscrewed everything and turned it off. When in doubt, go online.
- Be careful and careful, take your time.
Results
So, from this article you learned how to disassemble and clean your laptop from dust yourself.
The first time it may be a little difficult, but the second time, I assure you, it will be much easier! After all, the neural connections in your brain will already be established. 😉
Good luck to all! Any questions left - ask! 😉
Instructions
The laptop is more complex and compact system than a regular computer tower and when disassembling it you need to be very careful not to break the device and make it unusable. The analysis should begin with a thorough external examination. Turn the bottom upside down. On the bottom you will see covers under which various peripheral modules will be hidden - RAM, hard drive, Wi-Fi module and others. The first step is to remove the battery. Even if you have previously disconnected the laptop from the network, many of its components may be energized. Remove all the screws that you can see, but try not to lose sight of the screws hidden under the module covers and battery.
Now you need to remove all devices. The hard drive is usually removed by sliding it away from the connector. Some discs may have a special tab that makes this task easier. The next step is to remove the disk drive; its fastening screws are located on the bottom, but in some cases it may have additional fastenings underneath, and then you will have to wait a little while removing the drive. Disconnect the CPU cooler power cables and Wi-Fi module, remove the cooler. The need to periodically clean the cooler from dust may arise even if you work in a clean, ventilated area. You will be surprised at the layer of dust that has accumulated on the fan. If the cooler was your goal, then after cleaning it, you should reassemble the laptop in the reverse order of disassembly.
But this does not always help; sometimes there is a need to clean the radiator and update the thermal paste on the processor chip. Unscrew the radiator mounting screws. Usually the radiator is secured with 4 screws and one of them is hidden under the warranty sticker. If the old one is dry, it may take a little force to separate the heatsink from the processor, but remember, caution is everything, brute force can completely destroy your computer. At this point, you can finish working with the bottom and turn the laptop over to its normal position. All other mounting screws are located under the keyboard, in different laptops can be removed in different ways, but upon careful inspection, you can find grooves and latches in all of them, which can be used to remove the keyboard. Disconnect the keyboard cable. If you set out to get to the matrix, you will need to remove the top cover of the laptop. Don't forget to disconnect the matrix cable before doing this. Inspect the laptop for hidden screws and unscrew them. Remove its top cover. The matrix itself is attached to the housing using screws; upon dismantling, access to the inverter also becomes possible.
To remove the display, you need to remove the plugs located around the perimeter of the screen, unscrew the screws underneath them and remove them from the display with gentle force. By folding the cable, you can easily remove the display from the laptop. The extent to which you disassemble your laptop will depend on your ultimate goals, but remember, you must know exactly why you are disassembling it. If you are not confident in your abilities, then it is better to contact a special repair service; the specialists working there will cope with the disassembly much faster and better, and most importantly, they will not harm the computer due to the lack of necessary experience.
Almost any laptop sooner or later needs partial repair. Almost any repair requires disassembling the case. It is also necessary to clean the cooling system from dust and dirt from time to time. To do this you also need to disassemble the case. How to do this?
You will need
- laptop instruction manual, set of screwdrivers, light cloth or paper.
Instructions
First, we prepare the surface on which the disassembly procedure will be performed. It should be well lit so that small details can be easily seen. If there is little light in the room, install a table lamp. Place paper or light cloth. On a light surface, dark details will stand out clearly. This will help you avoid losing small parts. Before disassembling the laptop, you should make sure that the warranty period has expired. Otherwise, it is not recommended to disassemble the laptop. This may void your warranty. You also need to study the instruction manual for your gadget. In it you can find the design features of your particular laptop.
Turn off. Unplug the power adapter. Close the laptop lid until the locking mechanism clicks. Turn it face down. Now open the battery latch. Slide the latch and remove the battery from the compartment. Your laptop is now completely powerless. You don’t have to worry about losing data and settings, since in all modern laptops There is a small internal battery that allows you to store settings in memory for quite a long time.
Find all the screws that hold back cover housings. Unscrew them carefully. Try to remember the position of each screw. Now open the laptop lid. Using a plastic screwdriver, carefully pry up the panel above the keyboard. It is held on by plastic latches. Do everything very smoothly so that you don’t accidentally break these latches. There is a power button on the panel, which is connected to the board with a cable. Carefully disconnect the cable. At the edges you see two screws. They hold the monitor hinges. Unscrew them. In this case, you need to support the laptop lid. After this, you need to carefully disconnect all the connectors of the wires coming from the monitor. The laptop lid is detached.
Now start disassembling the case. It consists of two parts - upper and lower. In addition to screws, they are connected by plastic latches. Find and reveal them. Then disconnect the upper part of the case. The laptop is almost completely disassembled. All that remains is to get the right part and fix it.
Disassembly is divided into complete and incomplete. The first is carried out when replacing memory modules, hard drive and optical drive. The second is required to service the remaining nodes of the computer.
Instructions
Regardless of what kind of disassembly you want to do - complete or incomplete, before starting work, be sure to disconnect the power supply and all peripheral devices from the machine, and then remove the battery.
By tradition, such articles begin with a warning, and I will not break tradition.
Mindlessly following the instructions in this article may damage your laptop, be careful.
The main reasons for disassembling a laptop:
1. Upgrade
2. Replacing faulty parts inside the case
3. Cleaning the cooling system from dust, replacing thermal paste
4. Replacing the keyboard
5. Replacing the matrix (screen)
The complexity of the disassembly depends on the reason for the disassembly. I highly recommend finding instructions for disassembling your laptop model; it will indicate in detail and with pictures what to disassemble and in what order, but if there are no instructions, read on.
1. Disassembling the laptop for an upgrade.
As a rule, this is the simplest type of disassembly; replacing a hard drive or adding RAM is a standard procedure; in most cases, it is enough to unscrew a few screws on the bottom of the laptop and remove the covers covering the memory and hard drive and replace them. Occasionally you come across models where to replace the memory you have to remove the keyboard, or completely unscrew the bottom part of the laptop.
2. Replacing faulty parts inside the case
Sometimes it is possible to produce do-it-yourself repair laptop, disassembled and replaced faulty devices, wifi card, video card, RAM, hard drive, etc. The complexity of disassembly depends on the device being replaced; replacing a wifi card is more difficult than RAM or a hard drive, which are usually easier to access.
3. Cleaning the cooling system from dust
In most cases, to remove dust, the laptop will have to be disassembled almost completely; to replace thermal paste, it will have to be completely disassembled. You can determine whether the thermal paste needs to be replaced by eye by the age of the laptop and the mode of operation. If the laptop is 2-3 years old, and during operation it regularly warmed up, then most likely the thermal paste has already dried out and has ceased to perform its functions sufficiently.
4. Replacing the keyboard
As a rule, the keyboard is held on by latches and is additionally secured with screws from the bottom, so to replace it you will have to completely disassemble the laptop. Sometimes the screws holding the keyboard are accessible from the bottom of the laptop, in which case only a few screws can be removed.
5. Replacing the matrix (screen)
In the first 4 points, the laptop matrix was not affected in any way, and all actions can be carried out without removing the motherboard, but to replace the matrix in some models you will have to disassemble the laptop almost completely.
General algorithm for disassembling a laptop without instructions using the example of Lenovo ThinkPad Edge E430.
Before disassembling, turn off the power to the laptop, unplug the charger and disconnect it from the laptop.
Step 1.
Slide the latches towards the open lock icon and remove the battery

Unscrew the screws
To remove the keyboard Steps 3-11 are optional, you can skip them.
Step 3.
Remove the cover, now you have access to the insides of the laptop
CMOS battery - CMOS memory battery
Wireless card - wifi card
Hard drive - hard drive
Cooling fan - cooling system fan
RAM - random access memory modules
Step 4.
Unscrew the marked screw and pull the DVD drive in the direction indicated by the arrow.
Step 5.
Unscrew the screws holding the hard drive, slide it in the direction of the arrow.
Step 6.
Lift and remove the hard drive, Lenovo ThinkPad Edge E430 comes with standard 2.5 inch SATA hard disk, it can be replaced with ssd.
Step 7
Disconnect the CMOS memory battery, check its voltage, it should be about 3V, if it is lower, replace the battery.
Step 8
Disconnect antenna cables from wifi card
Unscrew the screw
Lift and remove the wifi card
Step 9
The cooling fan is held in place by 3 screws, unscrew them
