Ibm laptop going into hybernation after installing acpi driver

  1. hi,
    i have an ibm thinkpad a21m that was put together (mobo, hd, ram, cd, floppy, etc.). installed xp. worked fine. it had "unknown device" on device manager. i used msinfo32 to identify that it needed acpi (advanced configuration power interface). i installed it. the unknown device error went away. when i restarted the system, it keeps going into hybernation after 2-3 minutes. i unplugged cmos and main battery. reset hybernation option to never, reset all the bios to default. still goes into hybernation. my question is: would it go into hybernation if the cpu gets hot? or is there another problem that i'm overlooking?

    Most likely an overheating issue. Someone answered your post on another forum with good info so I won't retype it:
    Also look at the bios settings to disable anything related to Hibernation.

    thanks. i have a feeling that's it. because we installed a new cpu on this thing. my son told me that he doesn't think that he put enough thermal paste between the heat sink/fan and the cpu. so, i'm gonna look into that.
    thanks agian.
