Why is my laptop s touchpad malfunctioning all of a sudden?

It could be that the touchpad driver is corrupted or the user has accidentally uninstalled it.

The laptop touchpad is turned off. Some notebooks can turn off the touchpad through settings, so if you accidentally turn off the touchpad, it will naturally cause the touchpad to malfunction.

Caused by a virus in your computer.

The laptop's touchpad is faulty (e.g., water ingress, foreign objects inside, etc.).

Sudden failure of the laptop touchpad can be done as follows:

If the touchpad suddenly fails during use, you can restart the computer first, because some programs run errors, resulting in memory running errors, so that the touchpad will be temporarily unusable. If the problem persists, restart the computer again, then press the F8 key to enter the safe mode to boot, and select the correct configuration to boot in.

If the above methods still do not work, then conduct a virus investigation, use antivirus software to scan the computer completely, and if no suspicious virus is detected, you need to focus on the following two aspects:

1. First of all, check whether the touchpad function of the notebook is locked.

If you accidentally operate the computer and mistakenly press the button to turn off the touchpad, you may turn off the notebook touchpad, so when the touchpad is not available, you can try to press the FN+F6 key combination to open the touchpad (sensitive note: some notebooks may use FN+F6 to turn on or off, but there are also some brand notebooks that are different, you can check the instruction manual of the corresponding brand and model notebook, or search for the following information).

2. Then detect whether the touchpad drive is normal.

You can use the driver management software to uninstall the original touchpad driver, and then re-test the computer driver, update the touchpad driver, and re-test whether the touchpad is available after restarting the computer.

If the above methods still do not solve the problem of laptop touchpad failure, then you may wish to reinstall the system or restore the system to factory settings.
