HP Probook 450 G8 Touchpad is Unresponsive

A commonly reported issue is when the touchpad is not responsive, or the cursor is moving randomly without prompting.

If the touchpad is raised above the level of the keyboard, or if it appears in any way to be swollen, there is a chance that there is an issue with the internal components.

Some models of the HP Probook 450 G8 have a “double tap to disable” zone.

Attempt to turn the touchpad off and on by double tapping the top left corner of the touchpad. Double tapping may enable the touchpad if it had previously been disabled. Double tap again to re-enable if it does not result in a working touchpad according to HP Support.

Hold down the power button to shut it down completely .
Ensure that it is not plugged into anything. It must not be plugged into a wall charger with an AC adapter (a large box in the chord). Remove any attached printers, or other non-essential accessories.
With everything unplugged, hold down the power button for 15-30 full seconds to drain any residual power.
Plug it back into its wall charger with an AC adapter, and turn it back on normally.
