I had the same problem with another Thinkpad model, and looking for the
cause was driving me nuts.

Then I stumbled over #662183, where Thomas mentions the exact same
problem and a solution: resetting the BIOS. And indeed, that also worked
for me -- the issue is now resolved.

How about giving that a try?

Christian
