UserModePowerService causing shutdown?

Hello all - I'm completely new to Win8 but am currently using it on an Acer Revo RL70 as a media PC. Because the Acer Revo consumes such little power, I'd like it to run 24/7. Unfortunately,when I wake up in the mornings I always find it shut down. By searching event viewer, I noticed it always occurred at 1am ish. I initially thought it was my Windows Home Server 2011 backup fouling things up, so disabled this, but still the same problem.

I noticed 3 events precede the shutdown. The 3 events are all identical, and take place at the same time. The event is:

Info - UserModePowerService. Event ID: 12 Task Catagory: (10)
Process C:Windows\System32\atieclxx.exe (Process id 336) reset policy scheme from (8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c) to (8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c)

As you can see, the reset of the policy scheme is brinding up the same code/number. Following these 3 events is the

Info - User32 Event ID: 1074 Task catagory: none
The process c:windows\system32\winlogon.exe has initiated the shutdown of <pcname> on behalf of user/<pc name> for the following reason - no title for this reason could be found.

I'm afraid I'm not too clued up on windows event codes,but I cannot find much info on UserModePowerService or the event ID 12. I havefound that the atieclxx.exe program is from my (intergrated) graphics , but I do not know why it would want to shut down my PC

I have looked at the power options and have disabled all references to power saving and sleep.

Any advice on this would be greatky appreciated

Did you ever solve this? Also having the same issue

Hi,

Did you ever solve this issue? I am also having the same issue, but an Asus Windows 8 laptop.

Thanks,

Afraid not blundercrush - as a quick fix I put amended my power settings so that the PC would go to sleep before ever reaching the point where it would turn itself off (which was usually after 1.5-2 hours of inactivity).

Another method I used which seemed to work quite well was to select the event listed above in event viewer (the one that initiates the shutdown). Once selected, you can then right click and choose to create a task in response to the event (I can't remember the exact wording). You then instruct the task to abort (again, I can't remember the exact wording. I think its something simple like /a. Have a google for it). That seemed to work, but would also abort the regular nightly reboot task I had set up, so it had to go. As soon as I deactivated this task, the shutdowns came back, so it must have been doing something...

Good luck, and if you find the cause, please post on here and let me know, as it must be software related if we're both experiencing this on 2 separate, otherwise well functioning machines...
