The touchpad is not easy to use after the laptop is soaked in vinegar

This is a hard injury, if you can, you try to reload the machine, because my first judgment may be just his problem, because it still works. If not, this location is very troublesome and needs to be removed several layers before it can be taken out, you better not dismantle it, I have demolished it, the trouble is to death, and you don't want to spend money to repair it, there is a great chance of pit you. It's a few hundred dollars at every turn.

I think you try to reinstall the machine first.,Mainly the driver of the touch screen.,Or the screen is low and stained.,I've used a hair dryer before.,Please be sure to pay attention to the hair dryer and don't stop there all the time.,My keyboard let me brush it with water.,It's also very easy to use.,It's just to let me burn the keys of the keyboard.,Oh if you want to shake and bake.,You try carefully.,It's best to install it first.,Good luck,

Check to make sure: Is it the surface of the touchpad that is affected by residue that is causing the fingers to move smoothly?

Or is it contamination inside the touchpad that is causing poor sensitivity?

If it is a surface problem, you can use a toothbrush to apply a small amount of alcohol to scrub;

If it is an internal problem, it needs to be completely disassembled, cleaned and then installed (if it is not a professional, please send it to a repair point for processing).

It's hard to fix, because the vinegar has corroded some of the metal components inside, causing poor contact.

Let's change it.

Let's go to customer service to take a look, this place is prone to problems by itself, and they are more skilled

Enter the Control Panel - double-click [Mouse] to open the mouse properties - checked"Device setpoint"- Click"setpoint"- Checked"Strike"option, just turn on the tap function.

1.This may be due to accidentally turning off the touch screen, generally press fn (function key) + f6 (different keys for different notebooks, there is a touchpad image on the button) to unlock. Some computers also have buttons that open and close the touchpad directly.

2.Next, you can check if there is a problem with the driver. If you have reinstalled your computer, you should install the appropriate driver before trying to enable the touchpad.

3.Secondly, there is the issue of settings. Open the properties of the mouse in the control panel, you can see that there is a device setting value clicked, you can see that there is a setting value on the interface that comes out, and an interface comes out after clicking, and you can see that there is a touch on the left side of the interface, and there will be an enable touch on the right interface, and you can click to select it.

4.If there is still no response, it may be a hardware problem with the touch screen. However, since the touch screen is rarely broken, it is finally necessary to contact the relevant repairer after-sales service to deal with it.

How to say it well - my computer, properties. Hardware. Hardware devices. Mouse. Right-click inside to enable.

No more. Control panel surface. Mouse. There's it inside. Almost.

1. Detect whether the touchpad is turned off.

Lenovo turns on the shortcut keys to turn off the touchpad is the Fn+F6 key or press the F6 key directly.

2. Reinstall the touchpad driver.

The notebook touchpad also needs the support of the driver, if the driver is not installed or the touchpad is not installed correctly, the touchpad will not work normally, go to the official website of Lenovo notebook to install the corresponding driver and install it, pay attention to the corresponding notebook model.

3. Clean the touchpad.

If the touchpad is just not sensitive, you can use a damp cloth to clean the touchpad after turning it off, but be careful not to get liquids inside the laptop.

If the above 3 solutions cannot be solved, it is likely to be physically damaged with the touchpad, and ordinary users cannot repair it by themselves and can only send it to the service station for replacement.

Hello, it may be caused by a software program conflict, you can try to re-computer to see if it can be used normally, if it still does not work normally after restarting, you can uninstall the current trackpad driver, restart the computer and reinstall it.

At present, the touchpad of most laptops can be used directly without the need to install drivers.

Nearly half of the users who can't use the touchpad of the laptop are actually not the driver problem, but the shortcut switch of the touchpad is turned off (for example, Lenovo laptops use FN+F8 to turn off the touchpad).

Therefore, when the touchpad of the laptop cannot be used, it is recommended to first check whether there is a shortcut switch for the touchpad on the laptop, for example: check whether there is a touchpad icon on the F5 F12, and if so, use "FN + that button" to try.

If the computer's touchpad cannot be used after the system is replaced, and the system has been used normally before the system is replaced, it is recommended to check the official website of the notebook computer according to the model of the laptop.

For example, most notebooks no longer support XP systems, or some notebooks only support 64-bit systems and not 32-bit systems.

Open Device Manager, click"Mice and other pointing devices"to check if there is a disabled device or a device that is having problems, and if there is, enable it or install the driver wizard with the driver.

If the touchpad still can't be used normally after the above steps, then it is only recommended to send the computer to the official after-sales service outlets. Because it can't be used normally, it may be a hardware problem with the touchpad or a BIOS update and upgrade.

Landlord, there are three reasons: 1. The driver is not installed, you update the touchpad driver! 2. You may inadvertently turn off the touchpad, you use the shortcut key to open, generally the FN key + F9 key, the specific shortcut key, you see your computer manual, there is on it!

If the first two are not solved, it can only be the third possibility, that is, your touchpad is broken, then you can only go to the after-sales service station, if your computer is still in the three-pack period, it will give you free repair!

You see if there is anything similar to the keypad in the keyboard of F, find and then fn+ that key, if you still can't use it, click that key directly, and if you can't use it, it's a driver problem, reinstall or go to the driver wizard to see.

Find a function key on the function key that looks like a finger touching a board, and then press this key and the fn key at the same time to open the touchpad.

You see if it's turned off with the function key, if you press the function key and the mouse doesn't respond, you guess the cable is broken or the EC chip is broken.

1.Driver issues: Find the trackpad driver that comes with the disc mounted.

2.Dust Problem: Wipe the trackpad clean.

If it's really broken, go to the after-sales repair, and the hardware problem will not be solved here.

Or you need to pay attention to whether there is any special software installed recently that causes the touchpad to not work well recently.

See if the drive is good.

Do you buy a computer with a CD-ROM disc? I also had this problem, and then I put the disc to see if there was a relevant driver, but I put the disc into the computer not long after, and then I found that it could be sliding. I don't know what's going on, you try it, see if that disc has that touchpad driver, install.

Turn on and turn it off, and if it doesn't work, go into the factory for maintenance.

Is it that the boot startup item is not set to ???

If you don't have a disabling option,You can uninstall,Restart,But sometimes it will automatically install the driver when it starts.,It's okay.,Then disable the automatic installation of the driver.,There's a way:

Click to open the "Start Menu" -- Run", enter "Run" and press Enter.

Then in the settings page of Local Group Policyr, open Computer Configuration -- Admin Panel -- System.

Find "Device Installation" in the right window and double-click to open it.

Then on the page that opens, double-click on "Device Installation Restrictions".

Double-click "Device Installation Restrictions" to open the page and find the item in the image. Then I double-clicked and found that the touchpad was disabled successfully, which is my experience, and I don't know if it's right.

It is estimated that the interference of the power supply is too strong, just to get the touchpad.

Installing a touchpad driver is just fine.

If there are no devices with question marks or exclamation marks on them, then all the drivers are installed, in this case, the hardware is not working properly, maybe it's the hardware itself.

That's one more driver: hotkey driver, I have also installed dozens of HP laptop systems, as long as the hotkey driver is installed, the keyboard will fail, and it can be used normally when uninstalled. You can uninstall it in "Add & Remove Programs".

Look at your device manager to know that the system you choose is not suitable for your laptop. Let's change it.

Find Easy Display in the random disk, and the screen brightness, sound control, etc. can be used normally after installation. This one is the keyboard hotkey.

If you find that the keyboard or touchpad cannot be used after reinstalling the system on the laptop, follow the steps below to solve the problem:

1) Open Device Manager and check if there are built-in keyboard and touchpad devices listed in it.

2) If it is not listed, it proves that the hardware circuits of these two devices are faulty, resulting in them being unable to be identified, and the laptop should be sent for repair;

3) If the two devices are listed, but the status is abnormal (exclamation mark or question mark), you need to try to reinstall the motherboard chip driver, touchpad driver and driver. Reinstalling the above drivers will resolve the abnormal state of the device.

It's not that there is no drive ... It should be no problem to hit them all.。。
