Vista 64-bit hibernates during login

[Thargy]

This ones driving me absolutely crazy, as I've spent a whole weekend on it so
far...

The symptom: Within 5-10seconds of reaching the login screen my laptop
enters hibernate/standby mode, this will repeat until I get past the
'Welcome' screen to the desktop.

I have obviously gone through powercfg and attempted to prevent hibernate
(powercfg -h off) and have gone through the power management (powercfg.cpl)
advanced setting removing sleep and hibernate options, to no avail.

Prior to this I went through and disabled all start up programs, first using
Windows Defender and then the Autorun utility.

Even with all the startup programs removed and hibernate/sleep disabled, it
still hibernates!!!! I also uninstalled all my logitec drivers (including a
few die hard one!) just in case (they tend to be problematic).

This happens on a clean install of Vista 64-bit on my laptop. I have an
NVidia 8600GTM card.

My question is, is there anyway of detecting what is requesting the
hibernation??? Is it the laptop keyboard being faulty? I have scoured the
event logs with no hope.

I really would appreciate your help before I scrub the drive and install
Vista 32-bit (which will hopefully be better?!?!)

Thanks

The hybrid sleep feature and the hibernation feature in Windows Vista may
become unavailable after you use the Disk Cleanup Tool :

I would flash my BIOS and check to see if you have an ACPI driver that need
to be installed or updated. An unresolved item in Device Manager.

Thanks for the suggestion, unfortunately all my drivers appear up to date.

A system restore has had no effect either.

 

[Thargy]

Was that an automated response?? Only if you'd read my original post you
would have noted that I deliberately turned hibernation off using powercfg -h
off, because it's entering hibernation unexpectedly! I think turning
hibernation back on, won't help!

 

[John Barnes]

I would check BIOS settings and if you can flash to the latest even if that
is a repeat. Hibernation is a communication between the ACPI driver in
Windows and the BIOS ACPI settings.

 

[Thargy]

I'm afraid my BIOS is up to date (Compal 1.16) and there are no ACPI settings
in the BIOS menu.

As for my drivers, I've run Driver Detective against them and they're all up
to date.

Tearing my hair out on this one! It really is the most ridiculously obscure
Windows bug I've yet experienced. I mean what on earth would cause windows
to hibernate during login????

Note it doesn't happen on lock.

 

[Thargy]

Fascinating fact, it does happen if I Log out though! When I log back in it
goes to the Welcome screen and then hibernates, on resume I can log in (so
long as I'm quick).

I'm wondering if it's tied to a group policy, but I've used gpedit.msc and
can't see anything that would set it. I'm going to connect the laptop back
to the domain in the morning and see if there's any difference when it's on
the domain network...

How old is you BIOS? It should be under the Power Management (or similar)
section of most less than 5 year old BIOS's

The Compal 1.16 was released December 07.

Turns out the problem was some software provided by Compal called Smart
Watchdog! Uninstalling the service for this fixed the problem. It appears
to be a facial recognition system that switches off your machine if you're
not at your desk for a set period of time.

One of the worst Vista debugging experiences I've had yet!

Hope this helps someone else with the same problem.

Well that's certainly a "feature" that one needs as much as another hole in
the head. You said, you had this problem with a fresh install. What idiotic
computer manufacturer would include this piece of shit with its system?

Cheers.
