[ltp] Unsolicited requests for shut down

I had Psensor installed for a while and the temperature readings did not 
seem to make sense. For example, as soon as I turned on the computer and 
the temperature was still low, I would start compressing files and the 
Shut Down request would come up. By cancelling and carrying on, the 
temperature would increase but no other request would come up. I do not 
think that the temperature ever went over 60 degrees C anyway and the 
cooling fan seems to be working as expected. Plus the motherboard has 
been replaced on this laptop for a different reason and the problem is 
there with both old and new.

Would any of the logs record the shutdown request, so that I can trace 
it back?
