New MVIF mobo (RMA exchange) has begun auto-waking from sleep. The screen does not awaken when this happens though it will if a key is pressed or the mouse is moved then the expected Login screen is displayed.
Q-code displayed is "30" which according to the Q-code table appears to indicate that the system is waking from S3 sleep. OK, that is in agreement with what we know about the symptom so far.
Not OC'd.
Latest UEFI BIOS with "Wake from" options disabled.
Standard "Balanced" Power Option in Win8.1x64 Control Panel.
Where to start figuring root cause...?
Thx
