That is an interesting workaround, certainly faster and cheaper than
replacing the system board.

I agree about trackpads.  Both my and my wife's laptops (a Dell w/ Ubuntu
pre-installed) had the trackpads disabled before the sun went down on their
first day.

The Lenovo Thinkpads have fallen to the bottom of Consumer Reports
reliability ratings.  I was starting to look for a different brand of laptop
with a trackpoint.
