    Windows 8.1 update check wakes laptop, won't sleep again


    My general practice is to put my laptop to sleep when I'm done for the day, leaving it plugged in. I wait until it confirms sleep mode (flashing power button) and then close the lid (it stays asleep).

    The next morning I come back and the laptop is on and quite warm.

    powercfg /LASTWAKE shows this:
    Wake History Count - 1
    Wake History [0]
    Wake Source Count - 0


    I checked Windows Update and it did check for updates at 6:00AM this morning. So that must have awakened it. BUT... why didn't the laptop go back to sleep?

    I went to the Action Center and discovered that the maintenance check is done at 3AM, but the checkbox to automatically wake the computer from sleep was unchecked... which means it should not launch if the laptop is sleeping. In any event, I have set it to 11PM and will see if that makes a difference.

Hi, That's the question. I have my computer in my bedroom, so this is a real pain! The automatic maintenance is scheduled to 10am (I rescheduled it on purchase, when it annoyed the hell out of me at 3am). That one also still works and I'm fine with that. But it's just acquired without my...
I've got a weird problem where after putting my laptop to sleep for the night I'll find it half-awake the next morning. By half-awake I mean that the computer is clearly active, hard drive is spinning and the fan is going but the screen is not on and I am not able to turn it on by any means...
I've actually had this problem for a while, I really should have taken care of it sooner. It is mostly because I found ways around it, which probably aren't too good for my computer. If I leave music running in the background and put the computer to sleep then the error won't occur. Needless-to-say...
My laptop with Win 8.1 Pro x64 has two issues with power states which are not working correcttly. They are: 1-the laptop does not shut down completely; either by navigating to the power down option on the settings charm bar or by pressing the power button on the laptop (I set it to shut down...
This began recently (with the 8.1 update). It'll wake up out of the blue (the monitor doesn't seem to turn on until I wiggle the mouse though) and then after like a minute it's back to sleep. I disabled the mouse from being able to wake it up and it's still doing it. Any ideas?
