I've set up my motherboard and Windows (see signature for details) to use Standby mode. The PC will go into standby after 20 minutes of idle or if I press the sleep button on my keyboard. It appears to be going into standby correctly as Windows says "Preparing to Standby" and the computer turns off after a couple of seconds. When I press the power button on my MCE remote or on the case the computer comes to life but rather than resuming into windows it does a restart.
Does anyone know what I might be doing wrong? As far as I can tell I have the bios setup correctly.
