The touchpad (trackpad) on a laptop is not responding well.
I noticed that the surface of the touchpad is worn in some areas, but not others.
Are there any lifehacks to help the touchpad respond like when it was new?
Capacitance changes with humidity.
Trackpads and touch sensitive screens need enough humidity to work optimally. If you moisten your finger very slightly by breathing on it or the track pad itself, does the response improve?
Try increasing the humidity of your environment with some plants close by.
