    Cannot figure out what is now waking computer


    This started a few days ago and I can not find the culprit. Monitor will go to sleep, only to wake up at some unknown interval; if I manually put the computer to sleep, such as around 2100 last night, I will find it awake, as I did this morning at 0430.

    The other computer was also awake last night, so I put it to sleep; it was asleep at 0430, but awake at 0618; time that it woke up unknown.

    Only change made on both computers over past forty-eight or so hours was to enable hibernation, to try to ascertain why APC PowerChute software is not working with Windows 10. Is there any possibility that that could be causing problems? Yes, I know, and shall disable it to test, but want to ask here anyway.

    These items pertain only to my computer; I have not looked at anything on my wife's machine:

    1. Keyboard and mouse are the only things authorized to wake it.

    2. Event viewer shows a wake-time, but does not state what woke the machine.

    3. Possibly unrelated, but strange: Task Scheduler/Task Status shows not a single task for the past seven days, but an error message about a selected task no longer exists pops up, and says to refresh; refresh does nothing. The Active Tasks list shows lots of tasks scheduled for today and tomorrow, even a few for later.

    I started checking possible wake-up matters around 0445 local this morning, so I may have forgotten to post other things that I may have looked at.

    Windows 8.1 64-bit Pro, Windows 10 64-bit Pro TP

    I have noticed it coming awake if Windows is 'silently' downloading some updates. I saw this early this week I believe. Although, I have seen this happen on my 8.1 Pro rig many times and it was to the point it would be so bright it woke me up in the wee hours of the morning.

    In advanced power options, maximize sleep & allow wake timers and set it to "Important wake timers only".

    Personally I only allow the keyboard to wake the system (mouse & network adapter wake disabled), because any little vibration on the mouse can wake it.

    Interesting possibility, but I see no updates since the problem with the spurious printer-driver update that I reported in another thread, which last took place 04Aug2015.

    I just changed that setting; it is certainly possible that I had set it to Enable on both machines, something that I don't remember having done. However, as my religion bans the use of personal memory....

    Later: I do recall having set that to "enable" on my computer: For yet another inexplicable reason (or perhaps a lack thereof,) when I enabled Hibernation, that disabled my Power settings entirely; when I re-enabled them, I did make changes, and that was extremely likely to have been a setting that I chose. (Again, I have yet to check the wife's computer, so don't know what the setting is there; I will get to her machine later.)

    Recently I installed a Logitech wireless mouse that kept waking my computer. I changed to a different mouse and the problem went away.

    Possible, but, I have had a Logitech wireless mouse for at least a month now without wake-up problems, and the Logitech mouse on my wife's computer is wired.

    The 'Allow wake timers' option is bugged or at least it was yesterday prior to SR1.
    Even if you set it to disabled it still allows wake timers, so check in command prompt with :
    powercfg /waketimers
    This is different from powercfg /devicequery wake_armed which shows which devices are allowed to wake pc
    If you have anything in waketimers that can wake your computer it probably will. For me it was Teamviewer.

    It is possible that PowerChute is causing your computer to wake up. Have you checked to see if it is the problem by uninstalling it yet? If you conclude that it is not the problem, try disabling computer wake up by your internet adapter. I had a similar issue with an old Windows Vista computer, and it was being caused by the network adapter waking the computer up. How to Stop Network Activity from Waking Your Windows PC
