I know it's been done to death, but I can't find an answer after searching for a couple of hours... I've just had to reformat my media centre following a HDD failure, now I can't get it to wake from S3 via remote. My symptoms, whilst running the LED on the remote sensor is permenantly lit, remote will put it into S3 but it appears there is no power to the IR receiver in standby as the light is out and doesn't respond. Strangely 2 years ago when I first set the machine up it only ever went to S1 without the registry hack. I've looked at the registry hack this time but don't have a folder named USB at the following location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usb I've not touched the bios as it did work before the format. Hopefully I've just missed something stupid. OS is XP MCE 2005 Ta for any advice.
