Hello there, I'm Gopal an Independent Advisor. I will try my best to help you.
If your touchpad isn’t working, it may be a result of a missing or out-of-date driver. Updating or reinstalling your touchpad drivers in Device Manager may help solve the problem.
To update the driver
Press the Windows key + X, and select Device Manager.
Expand the Mice and other pointing devices category.
Right-click on your touchpad driver and select Update driver.
Select Search automatically for updated driver software.
Windows will search for and install the latest driver for your touchpad.
Once the driver is installed, restart your computer.
If the issue persists, please try to uninstall and reinstall the driver
Open Device Manager.
Expand the Mice and other pointing devices category.
Right-click on the touchpad driver and select "Uninstall device" from the context menu. Confirm the uninstallation if prompted.
Once the driver is installed, restart your computer.
