Computer won't stay in hibernate

[Soviet_Genius]

I'm running windows vista, i got it to hibernate, but the computer just turns back on. Sometimes it turns on instantly, sometimes it takes 10 minutes, sometimes hours. What is wrong?

Is wake on LAN enabled in the BIOS ? ?
If it is a program phoning home for updates will take it out of hibernation...

I'm a bit confused here. Hibernated computers aren't running programs, and wake on LAN works when an incoming packet is received... Isn't that right? Could it be e.g. a peer to peer program where your IP is being pinged because of a previous connection?

It could be that, and it can also be a server that was connected to while browsing and did not receive a disconnect. After a period of inactivity, many servers will check to see if the connection is still "live" before doing an automatic disconnect. Sometimes you have to disable wake on line in the NIC's properties as well as BIOS to prevent software overrides.

So I should go into BIOS and try to find a setting that has to do with networking?

It's usually called "Wake on LAN".

Maybe also change the BIOS settings for power saving from S1 & S3 to just S3 (STR).

You do mean hibernate and not suspend? (They are different)

I don't know what to change, I took pictures of each menu:

In the Power menu, set "WOL in S4" to "Disabled".

WOL = Wake On LAN.

S4 = Hibernation.

It is currently set to "Enabled".

Thanks, I'll try leaving it hibernated overnight.
