Strange Hibernation Issues

#1
Ok, so I have ACPI 2.0 installed, and I have all the settings in the "Power Options" that allow a timed hibernate, disabled. However, when I leave the PC on it will hybrid sleep after a few hours and then when I try to resume, it instantly turns on (like its supposed to) but then, after about a minute or two it hibernates. I can't stop it from hibernating, and I have to wait till it shuts itself down. Please advise.

I have a similar issue, tho it's intermittent. After hibernating, powering on brings up the "Resuming Windows" screen, then the login screen, but intermittently the computer will sleep within about 15 seconds of reaching the login screen, as if I had taken too long to login. It sleeps even as I'm typing my password, or even after during the login process!

No idea at all.
