Hi.
I have a Thinkpad P1 Gen 7 and I have problems with the touchpad.
It starts out fine, no problems. But over time (after 15-30 minutes of active use of the touchpad) the finger tracking becomes terrible - the cursor periodically twitches, tracking almost always disappears after 3 seconds, you have to lift your finger and lower it again. Rebooting does not fix this, all the drivers are the latest.
The only thing that helps is resetting the static charge by holding the power button for 90-120 seconds.
See how the touchpad works in the BIOS:

In Windows, of course, it looks different because of the drivers.
