ThinkPad T14 G1: mainboard replaced during first 6 months (cursor moving alone, with jitter, random crashes).

Now 4.5 years in: cursor moving randomly, with jitter (the same symptom as before), when TouchPad is activated. Plus: barely used trackpoint is defect.

That device was mainly used with an external keyboard and mouse -- no excessive usage of the built-ins.
