hibernation enigma

[eric]

Hello,

I have a hibernation question. My computer hiberates fine. The only
thing is it wakes up all by itself. I go into hibernation using
"Start" "turn off computer" and "H" key, or "Turn off computer" and
shift key to activate it in the shut down menu. It hibernates fine.

After say 15 minutes, or 30 minutes, it wakes up out of hibernation
all by itself. Fans begin to whir and it starts up. No person or
animal is near the PC.

So.., what activity is pre-programmed to wake it from hibernation? Is
it a setting in the bios? Something in winxp itself? Something I leave
open?

any help appreciated,

thanks, eric

Hi,

Possibly a bios setting. Look for a "wake on..." feature that is enabled and
try disabling it.

Hi,
I've been into the bios and disabled all the "wake-on's'' I found in
power management. It's an Asus P4pe motherboard. They were already
disabled anyway.

Does anyone know if any of the standard Micrososft programs can
produce this effect like MS Messenger for example?

I suspect some software within WinXP

thanks

Hi Eric,

Hibernation mode shuts everything down and copies the contents of ram to the
hard drive. In general, nothing in the system itself should be running,
including any scheduled tasks. The problem here is usually an outside
influence on the system, such as the suggested wake-on features. These this
will have the effect of waking the system up and taking it out of
hibernation. If the system is left connected to a network, try disconnecting
it. If power management is enabled in the system BIOS, you may need to
disable it there, as it could be conflicting with the Win-based settings.
Also check the power down state, perhaps you are only actually getting to
S3, and not S4? If this is the case, then the problem may be software based,
as an S3 standby state would allow tasks to run.

Hello Rick,

Ok, got that. So that leaves Bios and hardware.

The problem here is usually an outside
influence on the system, such as the suggested wake-on features. These this
will have the effect of waking the system up and taking it out of
hibernation. If the system is left connected to a network, try disconnecting
it.

Ok, i'll try this... sounds probable. Although the other computer is
not sending as far as I know

If power management is enabled in the system BIOS, you may need to
disable it there, as it could be conflicting with the Win-based settings.

Disabled Power Management in thwe Bios and still thes ame, something
like clockwork at a half an bhpur, the computer wakes up.

Also check the power down state, perhaps you are only actually getting to
S3, and not S4? If this is the case, then the problem may be software based,
as an S3 standby state would allow tasks to run.

Ok, how do I test for this? S3 or S4?

I did this, disconnected my network drives, and still after about 20
minutes, it woke up from Hibernation.

Rats!

Hi Eric,

The powerdown state should be in the system bios as well. Although the other
machine on the network may not be accessing this system, something from
outside it may be pinging it.
