Comment 114 for bug 1167624

Got this freeze again today, but in a new twist, the hardware power switch was also completely unresponsive. The fan was going crazy, but I couldn't get the unit to shut off. I could still adjust the keyboard backlight and check the battery level using the external control, but otherwise the unit did not respond.

All I could do was unplug it and wait for the battery to run out. Once that happened, I plugged it back in and it started up again as if nothing was wrong (the external power switch works again).

If it helps a diagnosis, I had put the unit in suspend while I went to lunch. Not sure exactly when it happened, but it was frozen when I came back 30 mins later.
