Since upgrading to 8.1 my Surface Pro will reboot when it should have gone into Sleep mode.... not every time, but if the machine has not been used for a while (e.g. over an hour or so). Prior to the upgrade it was very reliable.
For example, this morning the following messages were in my Event Viewer
The previous system shutdown at 20:18:39 on 18/10/2013 was unexpected.
Windows failed to resume from hibernate with error status 0xC0000411.
The message previous to this was...
The system has returned from a low power state.
Sleep Time: 2013-10-18T18:00:59.127876100Z
Wake Time: 2013-10-18T19:08:25.476268900Z
Wake Source: Power Button
Sleep mode was entered at 19:01, not mains connected, but battery fully charged (and still charged in the morning).
Any ideas?

I'll give anything a try..... before I resort to a Reset! Have just done what you suggest...... and will now wait and see. Thanks for taking the trouble to make the suggestion.
Just remember -- you aren't the only one with the problem... wiping the computer isn't a guaranteed fix.

My computer was shutting down unexpectedly when I put it to sleep. I fixed this problem by going to Choose what the power button does. Then I set it to Shut Downand saved it. Then I pressed the button and the computer shut down. After turning it back on, I went back to Choose what the power button does and switched it back to Sleep. now it works for me!
This might have fixed the problem for you and I don't doubt that is a possibility -- but keep in mind that coincidence might also be a possibility here: We've already seen that this problem can be inconsistent at times...

I don't have a key board attached and mine is still shutting down instead of going to sleep.
