What registry key enables the resume from stanby using the keyboard

We are implementing a GPO to put our workstations into standy after a set period of time. I would like to bring them out of standby by using the keyboard but cannot find the registry key to tick the "allow this device to bring the computer out of standby" checkbox in the power management properties of the keyboard. thanks.

This is mine.....

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\VID_04F2&PID_0210&MI_00\7&2242ae55&0&0000\Device Parameters

This means the "allow this device to wake the computer" is checked... 0 is unchecked. Mine is a USB keyboard....

Thanks for the comments. I have used regmon to identify the registry key and changing the values does work. I do however have a problem whereby this key is different on each of our workstations. Is there a a way of rolling this out so it will work on all our PC's.

You would have to have some fancy scripting to detect if a key exists, and then add a reg value if the proper %errorlevel% is found.....

Im sure it is easier in VBS, but I dont use that unfortunately...
Thanks again Johnb6767, but the problem does not seem to be they key existing or not.
It seems the hardware defines the key "path". A PS2 keyboard has a key totally different from a USB keyboard, and even if a USB keyboard is connected through a hub or KVM, it will be different from others.

What we need is a generic key or some alternative way to roll this out... or we will have to do it by hand, one by one.

Thanx again.
Take some time to collect a handful of reg paths, and I will see if I can come up with a script......

Maybe we can get most of them at least.....
Description of how to enable the S3 system power state for standby when USB devices are armed for wake
Thanks for your reply, dstewartjr, but this article assumes your keyboard has been previously enabled to wake the computer up. However, what we need is a way to enable this feature in multiple computers (by adding a registry key through a login script) so that we don't need to do all of them by hand.

johnb6767, going through the registry of most of the machines would actually be more work than just enabling every keyboard by hand...

Thanx for trying anyway.
assumption or not, but doesnt this article list a registry entry that can be used?
Not really. What the mentioned registry key does is enable S3 instead of S1 when the keyboard has been enabled to wake the machine up.

"By using the following registry entry, you can override entering the S1 system power state as a default behavior when a USB device is enabled to wake the computer".

Again, thanx for trying.
Although this was not an absolute answer to our problem it pointed us in the right direction. This will work for a single station but not for many.
