I have 3 systems that are relavitly new like 3 months. i turned off system standby, hibernate, and set turn off hand disk and everything else to never in the power managment in the control panel. yet they still go into standby after about a half hour. when i say they go to standby i mean the power light flashes and you have to press it to get the system back up. i checked the bios and no mention of standby mode. this is an option to use s1 or s3 power settings. I tried using both and it does the same thing. the systems are dell gx280’s. anyone have any idea’s?
