PC refuses to stay in Hibernation

[mrochester]

Hi I use hibernation on my Vista PC everyday. I've just got a new mobo, CPU and RAM, and now this new computer refuses to stay in hibernation. It switches off, but seconds later, powers itself back on again.

I've taken all the usual steps of checking the bios to make sure all 'Wake on...' settings are disabled, which they are. I've also gone through both network card properties in Device Manager to set their 'Wake up capabilities' under the advanced tab to None, without any success.

There must be some other setting that I'm missing to make hibernation work properly.

Any advice greatly appreciated.

Thanks,

Michael.

For what it's worth, mine does exactly the same.
Always has, since I installed Vista in Jan '07.

The same system hibernates fine in XP however.

One thing I have found is, if I go to the bios, and change the power management settings, if I change from Auto to.. I think it was S1, one of the manual ones anyway, then hibernate mode does work, except my chasis fans continue to spin, which is useless to me, as I wanted to use hibernate to silence the system completely, but be able to power it up quickly as well.

Hope you have better luck, and feel free to post back any solutions you find

I found later on that my system wouldn't even stay shut down... it would start up again a few seconds later. Luckily, completely resetting the BIOS with the jumper on the mobo did the trick and now hibernate, shutdown and sleep do work.
