I was refurbishing an NEC Pentium II laptop that seemed to be running hotter than expected. I also have the next generation model, which is a Pentium III, where the thermal paste had calcified to the extent that it needed to be removed with a screwdriver, and I expected something similar here. I was however, surprised at what I found.

Whomever installed the thermal pad on the top of this unit failed to remove the tape on the side which contacts the chassis, which is meant to act as an additional passive heatsink. I've never seen anything like this before.
