    L502x automatically reboots immediately on hibernation?

    Okay, I have weird problem I'm trying to track down. If I put the computer into hibernation, as soon as it completes the shutdown it automatically reboots and resumes again.

    Several things happened simultaneously or near-simultaneously to this starting:

    Installed three May 11 Windows Updates
    Installed the trial of VMWare Workstation 7
    McAfee updated itself.
    I did a repaste of both the CPU and GPU.
    Updated to A05 BIOS.

    Initially I tried doing a system restore to pre-all of this and hibernate seemed to be functioning normally. I tried each of these things manually and none seemed to cause the problem. Then the problem came back. So I tried downgrading the BIOS--no change. System Restores aren't working either, though it looks like I don't have the restore point that worked anymore.

    Anyway, I was curious if anyone else was running into this problem, to see what it might be related to? Or any brainstorms would be nice... I'm going to try a factory restore and I'll report back.

    Well I factory restored and reinstalled everything (except the VMWare, I don't need it) and no recurrence. *shrugs*

    I'm getting the same issue with the same laptop.. but when turning it off. At the moment I'm just turning it off during the bios screen, but will search for a solution. Reformatting would be annoying.

    I'm not even sure why it would be doing it, because theoretically the BIOS would be in control of the computer turning on from the "off" state. The only thing I can think of is if the "restart" bit which the OS must set when telling the BIOS to reboot instead of shut down somehow got stuck... what if you try purposely doing a restart to see if it clears it?

    This is just brainstorming here though.
