Just how does hibernation in 2k work

[videobruce]

I don't mean what it does, but just how does it do it?

How/where on the MB's bios does the O/S send the commands to to wake the system up and how is that different than you pressing the power button after you put the system into hibernation?
MS's site is useless all I came up with were issues with USB devices when I searched under "hibernation".

I have 2 problems. A program uses hibernation to wake the system up to record a HD TV program via a HD tuner card. First, the system was beeping with a post code of 25 (Award doesn't list a code 25 except for "reserved"), now it doesn't even wake the system up. It will record the program if the system is left on though.

To compound things, I have 2 bootable HDD's, each with 2k on them. They can be selected at startup (master or slave) via a toggle switch. They both have the S/W for the card and it was after (I beleive) I started tring to troubleshoot this that the 2nd problem started; it wouldn't even wake the system back up (using either drive). I'm guessing, but I think the 2nd drive corrupted something somewhere; Bios or O/S hibernation files. I did uncheck the 'enable hibernation', reboot and then recheck 'enable hiberenation', but the same thing. I also reflashed the bios, and set the default values, but no luck there.

Wiping the drive and reinstalling the O/S isn't doing anything with the BIOS on the MB, so I don't want to just 'try that'.

Any ideas??

BTW, I'm running 2k w/sp4 and a nForce2 chipset and a 9600Pro Powercolor video card. The MB's bios is 2/04, I don't overclock and I checked for viruses.

The HIGHLY TECHNICAL forum is not for troubleshooting.

I think it just saves everything in the memory and shuts down.

Yes I know that, but what is the difference between me restarting the system and the system starting itself???


BTW, I just LOVE your pic sig!

In hibernation, the system is OFF, and the OS isn't running. The OS can't do anything.

This means the tuner card is aware it needs to wake up the system, and remains "on" even when the computer is off. Either that, or you BIOS lets you automatically boot at certain times (I know mine does). If it's the latter, you should be able to see those options somewhere in the BIOS. Give them a try by setting a date manually and see what happens.

Correct, the OS has nothing to do with anything when the computer is off, and doesn't come into play until after POST, when the bootloader is executed.

Any ideas??

Highly Technical isn't for support. You'd get more readers in General Hardware.
