Hi
I'm running a clean install of Win 10 (build 9926). When I schedule tasks to run, they do not wake the computer from S3 sleep mode. If I run Win 8.1 on the same computer, scheduled tasks do wake the computer from S3 sleep.
Details / Things I have tried ...
- Dual boot computer (Win 10 & Win 8.1) - Win 10 is the default boot.
- Medion MS-7848 motherboard (i7 CPU + 8GB RAM) with the latest BIOS (1.07)
- Latest Windows updates applied
- Latest motherboard drivers installed (although they are officially for Win 8)
- Control Panel -> Power Options: Wake timers are enabled and Password not required on wake-up
After scheduling the task in Task Scheduler, running the command "powercfg -waketimers" shows that a wake timer has been set for the task.
Under Win10, the computer doesn't even wake up physically (whirring of disks etc) at the appointed time, let alone get to Windows.
There is nothing in the Event Log between the time that the system went to sleep and the time that I woke it again by pressing the space bar (which was comfortably after the time set for the scheduled task).
BIOS has been set to enable wake from PCI, RTC and USB. If I set an explicit RTC wake-up time in the BIOS, it does wake up the computer from S3 sleep at the specified time.
When I run similar tasks under Win 8.1 on the same computer, waking from S3 sleep works perfectly.
Clues gratefully received ...
