Vista Hybrid Sleep Problem

I just built a new system for one of the executives in my company and loaded it with Windows Vista Business. I want to configure the hybrid sleep mode so that when the power option in the start menu is hit, the computer hybrid sleeps (the power button should flash slowly). I want the same function to occur when I press the power button on the tower. As of now, when I press the power button on the tower or in the start menu, the computer will enter hybrid sleep for a few seconds (the power light will flash as it should) but then it automatically pulls itself out of the sleep and desplays the log on screen again. I have already tried going into Control Panel>Power Settings and configuring the options there. I have already went into the registry to make sure than the hybrid sleep function is enabled (1), but I am still getting the same results. Any ideas?

Is it wrong to answer my own question?!?

Anyway…for anyone who might be interested, I have found a solution to my problem. After spending quite some time looking at various functions of powercfg.exe in Vista, I was able to determine my hardware was waking the system. As the mouse information was still being cached (even though the monitor shut off) this was waking the system.

from command prompt (as administrator) type powercfg -devicequery wake_armed
this will list devices that can bring the system out of sleep
simply go to device manager and the wake ability.

A little update to my issue…

If you disable the mouse’s ability to wake out of sleep, you won’t be able to use the mouse to break screensavers either, the only option will then be a keyboard or by pressing the power button on your computer. This may be a slight inconvenience, but I don’t think its anything that can’t be dealt with.
