4. At this time, the icon of the touchpad will appear in the tray area in the lower right corner of the desktop, right-click on the icon, and select "Tap instead of keystroke".

Second, if the above methods still do not apply, then first conduct a virus investigation, use antivirus software to scan the computer completely, and carry out antivirus and repair.

Third, if you accidentally operate the computer and mistakenly press the button to turn off the touchpad, you may turn off the touchpad of the notebook, so when the touchpad is not available, you can try to press the FN+ function combination key (generally one of F1-F12, with a small window sign) to turn on the touchpad.

Fifth, if the above methods still can't solve the laptop touchpad failure, then you can enter the BIOS, recall the factory default settings or restore the factory system after backing up the hard disk data.

Sixth, if it still can't be solved, then the problem is likely to be the fault of the touchpad itself, such as water ingress, internal foreign objects causing damage to the touchpad, etc., which need to be tested after sale.

Causes and Methods:

1. It may be that the touchpad driver is damaged or the user accidentally uninstalled it. Reinstall the driver.

2. 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. It needs to be turned back on.

3. Caused by viruses in the computer. Clean up the virus with antivirus software.
