hi, i dont' know whether this issue is already known... after installing the ATi-Tool my Computer didn't wake up from StandBy (ACPI S1) anymore, but i want to use StandBy furthermore. first i didn't realize that the ATi-Tool is the problem. with a little help from google and the little windows tool "sigverif" now i know that the driver "ATi-Tool.sys" caused the problem with StandBy. then i uninstalled the ATi-Tool and my system now wakes up correctly. so maybe some one could fix that issue in a future release?
