Are you sure it's not overheating?  The fact that it fails
consistently when you put the lid on seems to point to that, and so
does the fact that it failed when you moved it under your desk (less
airflow than the middle of the floor).  Try cleaning out whatever dust
and other crud has built up in your system's fan(s); if that doesn't
help matters, try using a bigger fan or adding another one.
