Thank you for your reply,
I Set S4 enabled in BIOS. Windows 7 POWERCFG still reports only S3 available. I also changed POWERCFG size to 100%. Does this MB support S4 under Windows 7?
This has never worked through 3 different BIOS versions so I do not think it is a BIOS corruption problem.
Are you saying I have to reinstall Windows when I change the S state in BIOS? That does not sound right to me. I do reboot.
I Would like to confirm that this SHOULD work before I RMA the board, if I even can.
