specify keyboard key to wakeup from suspend

Hello,

I'm wondering if its possible to select a specific keyboard key to wake up from suspend-to-ram.

By default, suspend-to-ram wakes up by any key on the keyboard. Is it possible to limit this to e.g.: "F4" only?

I have searched allot on the internet, but can't find an answer.

Thanks for any help.

If this is possible, this would be handled by the Bios. When the machine is suspended, the OS does not run at all and cannot see any key. It is the Bios that see the key and wake up the system. You can check if there is an option in your Bios; but I doubt what you want is possible.

This is weird, i have a IR remote connected to another computer(HTPC), this IR remote simulates a keyboard and mice (mceusb2), if my computer(HTPC) running XBMC goes to standby. it ONLY wake up pressing the "Power" button on the IR-Remote, which is a preferred result.
(I get the same result in Arch Linux Desktop computer if i connect the IR-dongle and enable wakeup via USB on that usb device.)

This is why I suspect that it is possible to specify the wakeup key-press on my keyboard (However, I may be mistaken).

In my bios can specify wakeup via LAN, wakeup via usb and wakeup via RTC.
