Public bug reported:

I've noticed that on some occasions after multiple suspend/resume cycles
that the touchpad can become unresponsive.  When this occurrs, the
trackpoint still functions well, but the touchpad and its buttons become
useless.

This seems to randomly occur.  I ran a 30 cycle test on this machine and
didn't see the issue occur, but did after closing and opening the lid 3
times, allowing it to suspend between each closure and open.

This has been seen on a couple systems only, (the other was the E320,
IIRC) and has not been observed yet on other Lenovo machines.
