Disable Power Management Shutdown

I have a laptop that had ...er... a considerable amount of liquid
spilled on it. It seems to have survived with only one serious
quirk. When I boot into windows on battery power, windows shuts down
- right at or before the login screen. Battery is fine, system will
run a linux kernel on batt power just fine, system runs winxp on ac
power just fine. Warrantee repairman said I need a new system board
to the tune of $750...so I think I'd like to just disable the power
management shutdown in windows completely - and save often. This is
xp pro with all the updates and drivers. I tried going into the power
management settings, but I don't see a way to do this.
Thanks in advance

The date and time was 1/12/2008 8:57 AM, and on a whim, Pachydermitis
pounded out on the keyboard:

I would guess that a driver that is being loaded by Windows for a
specific piece of hardware is crashing and shutting down (maybe due to
hardware failure or damage). I would be curious, can you boot using
Safe Mode on battery?

Possibly the Linux boot hasn't detected the faulty hardware, so it
doesn't crash.

I can boot into safe mode just fine. I tried it and the power
management doesn't work in safe mode. I also tried disabling some of
the power management features in bios and that let's me in. So if I
can just get windows to not shut me down in regular mode, I am good.

Have you tried a boot with logging enabled to show where it it choking?
That might give you an idea where to attack it.

It looks like it's caused by the cpu power saving feature (not the
speed step). I decided that I can live without that and disabled it
in the bios - no issues since. Thanks for all your help
