I downloaded shutdown.exe and everything works great when I SUSPEND (standby) the computer. The computer suspends automatically and starts up automatically. However, I still have the no hibernation problem. I don't have the hibernate BUTTON when I hold down the shift key, and when I use shutdown.exe to hibernate i get a WINDOWS error. "Insufficient system resources exist to complete the API". Anybody know how to fix this? SOUNDS like you may need the KB909095 fix from Microsoft.

The computer occasionally does not hibernate and you receive an "Insufficient System Resources Exist to Complete the API" error message in Windows XP with Service PACK 2, in Windows XP Tablet PC Edition 2005, or in Windows XP Media Center Edition 2005

SYMPTOMS

You use a computer that is running Microsoft Windows XP with Service Pack 2 (SP2), Microsoft Windows XP Tablet PC Edition 2005, or Microsoft Windows XP Media Center Edition 2005. When you try to put the computer in hibernation, the computer occasionally does not hibernate. When this problem occurs, you receive an error message that is similar to the following:

Insufficient System Resources Exist to Complete the API.

When you experience this problem, the hibernate feature is not available on the computer until you restart the computer.

This problem typically occurs when the computer uses 1 gigabyte (GB) or more of RAM.
