Touch pad does not respond when used.

One of the most common causes of the touchpad not working is that it is disabled or turned off.

Check to see if you have not accidentally pressed these keys. It is usually the Fn key that combines with an F key, such as F1.

Check to see that the touchpad is enabled in the mouse setting located in the Windows settings under the “Devices” tab. Something may have messed up and disabled the touchpad in these settings. These settings are located in Settings -> Devices -> Touchpad.
