The optical mouse does not work on an asus laptop. The touchpad (touch mouse) does not work on the laptop

Youtube

In this article we will try to give the most complete answer to the question why the mouse does not work and we will try to answer all related questions, such as: why the touchpad on a laptop or a wireless mouse may not work.
Almost every user sooner or later faces such a problem as malfunctions computer mouse. This can happen for many reasons, which, in turn, can be divided into two groups, depending on the source of the problem: hardware or software. What are these reasons, and how to eliminate them?

Reasons why the mouse may not work

Software

Software problems include:

Problems associated with the harmful operation of viruses,
failures or damage to the driver, as well as in case of opening damaged files, archives.

Hardware

Hardware problems are problems caused by damage to the mouse itself. These include:

Wire deformation;
Contacts are damaged or clogged with debris.

It often happens that a user, while working at a computer, drinks tea, coffee or some other drink and spills the liquid. This often results in the mouse being disabled.
By purchasing new mouse with a USB input, and if you find that the cursor refuses to move after connecting the device to the computer, do not rush to sound the alarm. Most likely, in the installed operating system the necessary drivers are missing.

Troubleshooting solutions

The good news for all users is that it is quite possible to cope with most malfunctions on your own. To do this, it is enough to have at least basic knowledge about the work of the hardware. So, the action plan is:

First of all, check your computer for viruses or other malware. You can do this using free antivirus programs, for example Avast.
If this does not help, then proceed to the next step: reinstall the mouse driver, which could very well be infected with a virus.
If this is not possible, try restoring previous version OS (operating system). How to do this in the video below:

Why the mouse does not work on a laptop: common reasons and ways to solve them

Reasons Why doesn't the mouse work on a laptop? there may be many. But this trouble is easily eliminated. First you need to determine what type of mouse is used for the laptop (touchpad, wired or wireless). Each type has its own characteristic causes of problems and ways to solve them.

Touchpad not working on laptop

If problems arise with the operation of the touchpad, they can be solved by correctly identifying the cause of the problem. So, the most common situations:

Not correct work(freezes, interruptions, cursor disappears from the screen).
The reason may be incorrect setting parameters. When installing, it is recommended to use the included driver.
Besides, Special attention Pay attention to the cleanliness of the touchpad - simple surface contamination reduces the sensitivity of the device.
It is forbidden to work with wet hands. To fix this problem, just clean the sensor from dirt and let it dry completely.
The device does not respond.

The reason is that the panel is disabled. Solutions:

if present, check the on/off button;
some models turn off touchpad when connecting an external device (wired or wireless mouse), turn off the additional pointing device;
V BIOS settings enable the support function for this panel (the enabled value for the Internal Pointing Device parameter).

If the problem cannot be resolved, you must contact the technical support center.

Reasons Why don't my mouse buttons work on my laptop? There may be problems with the mouse itself or a failure of the USB port, as well as incorrect connections and settings. To check, connect the mouse to a different socket or to another computer. If everything works, then you need to clean the input channels. Do not use long-haired rags or cotton wool as cleaning materials, and do not overdo the material with moisture. If the mouse does not react, it cannot be saved.
Wireless mice are becoming increasingly popular among users. The main problems with this type of mouse are:

Complete lack of response to manipulation;
Slow operation, freezing or slowing down.

The reasons for this may be:

the mouse is not connected (insert the adapter (USB receiver) into the USB port and turn the button on the mouse body into working condition);
The batteries are low (replace with new ones, and correct operation will be ensured again). The reason is quite banal, but many do not even suspect that the mouse is powered by batteries.
It is recommended not to use regular batteries, and batteries - this will prolong the operation of the device. In addition, if the manipulations described above did not help, you should check the functionality of the USB port to see if it is dirty. Perhaps the mouse itself is faulty. In this case, there is only one way out - replacing the mouse.

The mouse may not work also in individual applications, but this is an individual story for each application. In the meantime, as an example, here’s a video with a solution to the problem why the mouse doesn’t work in the GTA game:

Modern mice are precise and durable. And yet one day the computer may not respond to mouse movement.

The computer does not see the mouse: causes and troubleshooting methods

USB port is faulty

The reasons for the USB port not working are similar for all PCs running Windows.

Not enough power - Too many devices are connected to one port through a hub without external (auxiliary) power. Plug the mouse's USB connector into this port instead of a hub.

The USB port controller has failed. Contact a computer service center for repair of PCs and laptops; the controller board must be replaced.

The power supply (if you are using a classic system unit and not a laptop or tablet) has exhausted its power (the PC has been upgraded, mounted additional devices). Replace the power supply in system unit PC to a more powerful one.

The drawback of the front USB ports is when they all “sit” on the board of the same microcontroller. For example, if a hub with three simultaneously operating 4G modems and a printer are connected to two such USB ports, a failure is almost guaranteed: the modems will often lose cellular network or spontaneously break working connections (all at once or one by one), and the printer will “get stuck” without finishing printing a multi-page document. Most USB controllers do not draw a load current of more than 0.5 amperes. USB ports with enhanced power supply (1–2 amperes) are gradually replacing them - but if your PC or laptop was released in the “zero” and is already significantly outdated, this problem will haunt you constantly. If a mouse is connected, its control will often turn off due to overload.

Saving on controllers won't do you any good! Use extra food- modern USB-Hubs come with a separate power adapter!

Break in USB controller cables. You can repair broken wires yourself - but it is better to entrust this to specialists.

Make sure everything is intact

Damage to the USB connector and connector, their wear. Although everyone USB connector withstands up to 100,000 connections and disconnections external devices and cables with a USB connector, after years of active use In any of the USB ports, the contacts of the connector itself can be loosened, weakened - there is no reliable contact. will replace both the connector itself and the entire port or group of ports, including the controller itself.

A port that has been used constantly or carelessly can also break.

USB function is disabled in BIOS settings - enable it.

Make sure that USB functions active and configured for maximum performance

Short circuit of the wires through which power is supplied to the mouse as a result of a violation of the insulation of the mouse cable. The USB controller, of course, has protection against shorting any two or more wires - but when you try to reconnect a mouse or any other device, Windows message, for example: “Unable to connect to USB on this port.” Disconnect the mouse with the faulty cable, fix the short circuit in it and restart the PC.

For Apple computers Mac actions more simple.

Make sure the USB port is working. Paste work mouse or a USB flash drive. The flash drive will flash, which means USB port working, no - it is damaged. If the USB port works, do the following.

Check MacOS system for the presence of viruses. Having discovered software problems, reinstall MacOS, scan your PC for viruses.

Reinstall USB drivers for MacOS. Apple PCs must come with chipset drivers. You can find them on apple.com.

If the USB port malfunctions, contact an Apple service center - unlike other computers, Mac PCs are quite difficult to disassemble, so it’s better not to risk it yourself. It may happen that not only the USB port is faulty, but also south bridge main computer board.

If the USB port turns out to have nothing to do with it, most likely the mouse itself is not working. Buy a new Apple mouse or similar.

Mouse cable is faulty

Short circuit of two or more cable wires with each other, breakage of any of the wires. The USB interface is designed in such a way that all five “cores” - “+”, “-”, “data+” and “data-” and shielding - should not be broken. A break in any of these wires is guaranteed to lead to the inoperability of not only the mouse, but any device in general. It happens that due to the lack of a replacement for a damaged cable, a new mouse is required.

The mouse is damaged

Old-style mice, widespread in the 90s and the first half of the 2000s, were optical-mechanical: in addition to a light and photocell, controller and reader, they had a mechanical drive - a ball, rollers and a slot breaker. Now such mice have become rare - they have become purely optical.

This is what a disassembled mouse looks like

Besides faulty cable, mouse malfunctions may be as follows:

does not work main board(controller, reader, light and photocells);

the lens is dirty or scratched (rare, but it happens);

the wheel control unit is faulty;

the buttons are faulty (the mouse pointer moves on the screen, but commands from the buttons and the wheel - it also has a third button - do not go through).

Wireless mice are powered by one or two replaceable batteries or accumulators. The following may also be faulty:

clamping contacts (if poor quality, they may oxidize or rust);

power wires;

wireless module, which provides communication with a USB device (it can be several times smaller than a flash drive);

batteries (expired - replace them) or rechargeable batteries (discharged, need to be charged).

If the boards and controllers break down, the mouse definitely needs to be replaced.

Problems with mouse operation at the software level

General information about driver problems

Incompatibility of chipset drivers after replacing the Windows version with a newer one (or, conversely, an older one) may result in a failure of mouse control. Since the mouse/touchpad/sensor driver is usually included with all modern operating systems except MS-DOS, main reason mouse failure is considered inoperable USB drivers: This component is the "Universal Serial Controller" USB bus" and "USB Root Hub". Search the Internet for a version of the chipset driver that is suitable for the version of the operating system you are currently using. However, in Windows versions 8/8.1/10 all main chipset drivers are already components of the system - they do not need to be installed separately.

For Apple computers (for example, MacBook), mouse and touchpad drivers are also included in MacOS - when upgrading a version of MacOS, say, from Yosemite or El Capitan to Sierra, the mouse problem is only related to the lack of computer performance in the latest version of MacOS. But wireless mice like Magic Mouse require separate settings- necessary for their work bluetooth driver for MacOS.

Yes, on Acer netbooks, recommended for working specifically with Windows 7, when Windows installation 8/8.1/10 there was a problem with the netbook hardware - the chipset driver versions for Windows 7 were not suitable: the sensor stopped working (the mouse pointer did not respond), the wireless connection disappeared network connection etc. The best solution was to ignore these outdated drivers- after their removal and restart Windows the missing devices were working normally again.

All this suggests that in latest versions operating systems, be it Windows or Mac, graphical shell developers took into account and supported program level almost all functional blocks and components of a PC. This is why timely updates are needed.

Diagnostics of USB ports on a Windows PC

To reset USB controllers found on a Windows PC or laptop, do the following.

Give the command “Start - Control Panel - Device Manager”. (Computer - Management", "Device Manager" tab). Windows Device Manager will launch.

Give the command “Action - Update hardware configuration”.

Update the list of devices

Disable one or all of the existing USB controllers from the list. Select each one and delete it. After restarting Windows, all controllers will be updated.

Remove each one manually

If resetting and re-registering USB controllers after restarting Windows did not give anything, then the problem is somewhere else, for example, in the USB configuration.

Diagnose USB ports on a Mac

On MAC computers To regain control of the USB ports - and with them mouse control, reset the SMC (system management controller) parameters. For different models PC Mac way reset is different.

On a MacBook with no removable battery follow these steps.

Turn off your PC.

Connect the MagSafe or USB-C power adapter to the power supply and to the PC.

Press the key combination on your keyboard: Shift+Control+Option (left) and the power button.

Release all keys and the power button.

Turn on your PC.

On Mac laptops with a removable battery, do the following.

Turn off your PC, disconnect the MagSafe adapter from the PC, and remove the battery.

Hold power for a few seconds.

Connect the battery and MagSafe adapter and turn on the PC.

On Mac Pro, iMac and Mac mini

Turn off your PC

Unplug the power cord, wait 15 seconds, then plug the cord back in.

Wait another 5 seconds and turn on the PC.

Diagnose a wireless mouse on a Mac

Bluetooth mice are widely used. The Apple branded mouse, Magic Mouse, is taken as an example. You also need another mouse that works via USB. To test Bluetooth connectivity, do the following:

Go to System Settings Mac.

Go to Bluetooth settings.

Hold on the keyboard Ctrl key, left-click on the Magic Mouse in the Bluetooth paired devices window and click “Delete”.

You need to remove and re-register the Bluetooth mouse

Restart the mouse (on back side there is a switch).

Wait until the Bluetooth mouse appears in the devices window, establish a connection between the mouse and the PC via Bluetooth. Wait for a notification that the mouse has been successfully connected to your computer.

After reconnecting, Magic Mouse should work again. If the problem recurs, it may be bluetooth device it works incorrectly. Reinstall the Bluetooth driver. If nothing helps, even “clean” MacOS installation- Maybe, bluetooth module or the Magic Mouse itself is faulty. Contact the Apple Service Center to resolve any problems.

Incorrect USB setup in Windows

Automatically turning off USB ports is one of the protective measures against excessive consumption of electricity to power the computer and against excessive overheating. Unused in this moment ports are suspended. Disable this in Windows Power Options.

Give the command “Start - Control Panel - Power Options”, select your power plan and get to USB settings.

Disable temporary shutdown of USB ports.

It is not advisable to put the USB port in inactive mode

Although modern USB controllers supply power and control signals to the interface as soon as any device is connected, the port may not respond in time to the connection of a mouse. From failures in USB operation Neither Linux, nor Windows, nor MacOS are insured at all.

Checking USB controllers in Linux

operating room Linux system also allows you to manage USB ports on your PC. Supported different versions USB interface, including 2.0. For example, let's take a graphic Linux shell Gnome Ubuntu.

Launch the Terminal by giving the command “Applications - Accessories - Terminal”.

Enter necessary commands

Enter the required commands. To confirm, press the Enter key. Commands can also be freely copied from any text - using the combination Ctrl+Shift+V or using the mouse (much like in Windows).

The lspci command entered in the Linux terminal allows you to display USB devices. For example, let's take three USB controllers installed on a PC running Linux

root@localhost:~:# lspci grep -i usb

00:03.0 USB Controller: Silicon Integrated Systems USB 1.1 Controller (rev 0f)

00:03.1 USB Controller: Silicon Integrated Systems USB 1.1 Controller (rev 0f)

00:03.3 USB Controller: Silicon Integrated Systems USB 2.0 Controller

Now enter the lsmod command. For example, it will look like this:

Module Size Used by

hid_microsoft 3232 0 usbhid 32992 0

hid_microsoft,usb

hid ohci_hcd 24332 0

ssb 38464 1 ohci_hcd

ehci_hcd 34152 0

Be sure to check if your mouse is among the connected devices.

Other USB software glitches on any PC

Anything can disrupt the operation of USB ports - from incorrect installed drivers to viruses that launch extra copies system processes and overloading your computer's performance. One of the most protected operating systems from any Internet threats is MacOS.

Problems with the mouse on the tablet

Modern tablets Windows based and Android also support mouse operation via Bluetooth or via an OTG USB-microUSB adapter, to which both a classic mouse with a USB cable and a module from wireless mouse. After all, on a large 10-inch screen, using a mouse along with a keyboard when installing the tablet on a special stand is already relevant.

For Windows tablets, follow roughly the same steps as on a Windows PC or laptop.

On Android tablets current version operating room Android systems There must be system libraries that support mouse control of the tablet. If the pointer (or marker) does not appear on the display and there are no signs of controlling the tablet with a mouse, you may need to flash the Android system with official version to “custom” with replacement Android kernels or installation special application to control the tablet with the mouse.

As for the functionality of the microUSB ports, you can’t do without checking. First, check the OTG adapter itself - it is advisable to have at least two working adapters. If suspicion still falls on the microUSB port, connect a keyboard (possibly wireless), 3G/4G modem, flash drive, printer or something like that instead of a mouse. Try connecting two or three devices at once via a USB hub with external power. You will hardly notice that the microUSB port is faulty. In this case, you cannot do without specialists from a “mobile” or computer service center.

Video: how to fix a USB port on a laptop

Finding out why the mouse does not work is a task of quick wits, which, however, you can solve yourself, turning to specialists only in case of extreme necessity. You will succeed!

A mouse or pointing device is a device for controlling the cursor and transmitting some commands to the operating system. On laptops there is an analogue - a touchpad, but many users, due to various circumstances, prefer to use a mouse. In this case, situations may arise where it is impossible to use the manipulator due to its banal inoperability. In this article we will talk about why the mouse on a laptop may not work and how to deal with it.

In fact, there are not many reasons why a mouse may not work. Let's look at the main, most common ones.

Sensor contamination.
The connection port is not working.
The cord is damaged or the device itself is faulty.
Malfunction of the wireless module and other problems with Bluetooth.
Operating system failure.
Driver related problems.
Actions of malware.

No matter how trivial it may be, first check whether the device is connected to the port and whether the plug fits tightly into the socket. It often happens that someone or you yourself accidentally pulled out the cord or wireless adapter.

Reason 1: Sensor contamination

With prolonged use, various particles, dust, hairs, etc. may stick to the mouse sensor. This can lead to the fact that the manipulator will work intermittently or “brakes”, or completely refuse to function. To fix the problem, remove all excess from the sensor and wipe it with a cloth soaked in alcohol. It is not advisable to use cotton pads or swabs for this, as they can leave fibers, which we are trying to get rid of.

Reason 2: Connection ports

The USB ports to which the mouse is connected, like any other system components, can fail. The “easiest” problem is the usual mechanical damage due to long use. Less often the controller fails, but in this case all ports will refuse to work and repairs cannot be avoided. To solve this problem, try connecting the mouse to a different connector.

Reason 3: Device malfunction

This is another common problem. Mice, especially cheap office mice, have limited resource work. This applies to both electronic components, and buttons. If your device is more than a year old, it may well become unusable. To check, connect another, known working mouse to the port. If it works, then it’s time for the old one to go into the trash bin. A little advice: if you notice that the buttons on the manipulator begin to work “every time” or the cursor moves jerkily across the screen, then you need to purchase a new one as quickly as possible so as not to get into an unpleasant situation.

Reason 4: Problems with the radio module or Bluetooth

This section is similar in meaning to the previous one, but in this case the wireless module, both the receiver and the transmitter, may be faulty. To check this, you will have to find work mouse and connect it to your laptop. And yes, do not forget to make sure that the batteries or accumulators have required charge– the reason may be this.

Reason 5: OS failure

The operating system is a very complex complex in every sense and that is why various failures and malfunctions often occur in it. They can have consequences in the form of, among other things, failure of peripheral devices. In our case, this is a simple shutdown required driver. Such problems are most often solved by simply rebooting the OS.

Reason 6: Driver

A driver is a firmware that allows a device to interact with the OS. It is logical to assume that its malfunction can lead to the inability to use the mouse. You can try to restart the driver by connecting the controller to a different port, and it will be reinstalled. There is another way to restart - using "Device Manager".

Reason 7: Viruses

Malicious programs can make life much more difficult simple user. They can influence various processes in the operating system, including the operation of drivers. As mentioned above, without normal functioning For the latter, it may be impossible to use some devices, including a mouse. To detect and remove viruses, you should use special utilities, which are distributed free of charge by antivirus software developers and .

There are also resources online where trained specialists can help you get rid of pests completely free of charge. One such site is Safezone.cc.

Conclusion

As it becomes clear from everything written above, most problems with the mouse arise due to malfunctions of the device itself or due to software failures. In the first case, most likely, you will just have to purchase a new manipulator. Software problems usually do not have serious causes and can be solved by rebooting the driver or operating system.

Included personal computer A mouse is supplied; many people use a laptop or netbook on the panel for work, which has a built-in mouse. For many users this is not very convenient and they have to buy a mouse separately and then connect it to their laptop.

It often happens that after connecting a mouse, the pointer on the screen does not move, although the indicator inside the mouse glows red. What to do if the mouse on the computer does not work, but lights up?

It is worth noting that the computer industry produces two types of mice.

Mice produced:

With wire;
Without wire.

Let's figure out how these types of devices included with the PC work.

The wireless mouse works through a Bluetooth device. Batteries are inserted into the mouse and it is connected using a Bluetooth program, which must first be installed on your computer.

Once connected to your device, the mouse is ready to use. But, if after connecting the mouse pointer does not move, then you just need to restart your PC.

This action is often enough for the mouse to start working. If it doesn't help, you should try the mouse on another computer. Perhaps the mouse simply does not work due to mechanical failure.

Perhaps the electronic components of the mouse have failed, perhaps a wire has fallen off somewhere, or a radio component has failed.

The cause of the breakdown may also be the lack of the required driver, then you need to go to the mouse manufacturer’s website, download the driver to your computer, and install it.

Viruses and conflicts

The next reason why the mouse on the computer does not work, but lights up, may be a virus; in this case, check your device with the installed antivirus.

Sometimes a problem occurs after installing a program and a conflict occurs between the installed program and the mouse drivers.

Remember when the mouse stopped working and remove installed program or roll back the system to a working state.

But it also happens that the mouse stops working after Windows reinstallation. Maybe, software just doesn’t see the connected device, then you should change installed Windows to another OS.

Mouse with wire

Such a mouse should be tested on another computer to find out whether the device works or not. If the mouse is working, then you need to look for the cause of the problems on your computer.

The reason may be the lack of the necessary driver, a virus on the computer, or you installed downloaded software that caused a conflict between the computer and the mouse.

There is only one solution, if there is no driver, you need to download and install it, if this does not help, remember what program was installed on the device, after which the mouse stopped working. Find and remove software.

Mechanical problems

If the mouse refuses to work on other devices, then the reason may be mechanical failure. Sometimes, after disconnecting the mouse from the computer, the plug contacts may become bent.

In this case, you need to return them to their original position and insert the plug into the port socket. This can be done using ordinary tweezers or another device, for example, a thin nail, ballpoint pen and so on.

Mice with USB connector more durable and devoid of such unpleasant feature, they are more reliable in this regard.

Also, the cause of the problem may be the mouse wire; this happens rarely, but it happens if the wire was damaged by rodents or the wire was simply pinched by something heavy.

To do this, you need to pick up the connected mouse and start moving the wire. When moving damaged wire, the mouse indicator will start blinking. If this happens, it means you need to change the wire or buy a new mouse.

Sometimes a breakdown occurs when the device is simply dirty. To do this, you need to disassemble the device, remove any dirt or hair that has gotten under the mouse wheel, and the device will start working normally. It happens that the mouse works, but somehow sluggishly, actions occur with a delay.

Your computer settings are to blame for this and you need to try various options mouse sensitivity settings.

The mouse on the computer does not work, but it lights up, the result

As you can see, all problems can be solved. And if your mouse breaks down, you need to calmly figure out the problem and try to solve it using various troubleshooting options.

In the overwhelming majority, the user can solve the problem on his own. Unless the computer itself has failed. Then you need to take it in for repairs and solve the problem that way.

Finally, one small, but very important advice. If your mouse is under warranty repair, you don’t need to disassemble such a device yourself, otherwise you risk not being able to fix the mouse and may be left without warranty repair.

Take the mouse to a warranty repair shop, where your mouse will be repaired and returned to working order. Enjoy your experience on your device.
