Comment 52 for bug 969860

Regarding high CPU usage when screen turns off.

I might have had a real casualty of this bug. An 18 day old HP Pavilion g6 failed after being left unattended for about 1 hour while running Ubuntu. The laptop was on a hard smooth surface in an air conditioned environment. It was found fan running, warm to the touch and screen completely black. Nothing could be done to exit this state. The failed laptop was returned to a Compaq facility where I expect they are intent on finding the root cause of failure (I do not believe this was a repair facility).

The replacement HP Pavilion g6 (a slightly different model) is also warm to the touch when the screen turns off. Leading me to this bug report. Conclusions, the problems stated here may be the secondary cause of the first laptop's failure. The primary cause of course would be the laptop's inability to sustain high CPU usage.

(Some) information from the 2nd laptop:
