Computer Auto-Resumes from Hibernation

[cdd]

Hi,
The past four nights in a row, I have woken up to the sound of my computer auto-resuming from hibernation without me telling it to. The matter is not helped by the fact that it's a laptop. In the words of Microsoft, "the machine awakens at inopportune times and consumes the battery".
The first thing I checked was the 'Allow This Device To Bring The Computer Out Of Standby' checkbox on all the network adapters, they are all unchecked.
It's getting quite annoying.
Any ideas what this could be?
Thanks
Chris

Have you got any scheduled tasks for your computer to run at night? This could be waking your computer up.

[cdd]

Nope, none in Windows as far as I can tell. Just says 'Add Scheduled Task' in the Tasks window.

I thought Hibernation is the same as shutting down, apart from taking a RAM dump before dying. In other words, I wouldn't have thought it was possible to 'wake' up from.

Check the BIOS, the network itself may be waking it up, there should be an option as in the Windows Device menu to not "Allow this wake up" or something similar, that said I don't know if a laptop would have this. The only other suggestion is to turn the computer off and not stand-by/shut down. But if its only recently started, try doing a system restore or look at what you might of installed recently.

Yes (lukey) I thought that too, which gives me this sense that maybe it's some hardware problem - e.g. a dodgy contact on the Power button.
I've checked all these local devices and they all are set to Don't Wake Up.
The day it started (10th) all I have is something called 'Software Distribution Service 2.0' which sounds harmless enough.

I used to hibernate mine too, until last week when it steadfastly refused, and will no longer do it, will check out the above


(Only thing I have updated around the time it started was McAfee and Java, I also have the same software distribution 2.0 restore points as CDD)
