    My laptop has been randomly waking up at night from sleep mode at night and I have no idea why that is. In the device manager, Ive disabled all network adapters from waking up the laptop. Also in power management settings, Ive disables wake timers. When I look at the task scheduler, there is nothing out of the ordinary. The Event Viewer shows "Power Button" as the source of these random wake-ups, but I have not pressed the power button.

    So I'm completely lost here on what may be the problem here. Does anyone else have this problem or have any more ideas on what to try?

    From my experience many times what wakes the computer up is the mouse.
    Did u verify it is not allowed to wake the computer?

    When it wakes up by itself run

    powercfg -lastwake

    From command line and post the results.

    Other than the standard touchpad, Ive got a bluetooth mouse attached. With my bluetooth device, the option for "Allow Device to Wake Computer" is blanked out. Result of powercfg -lastwake

    Wake History Count - 1
    Wake History [0]
    Wake Source Count - 1
    Wake Source [0]
    Type: Fixed Feature
    Power Button


    This is weird because obviously my lid is closed and I didn't press the power button. Also, the event viewer shows power button as my wake source.

    Thanks, appreciate it. This problem has happened occasionally in the past, but only recently has it been happening atleast once a week (I wonder if it's due to the new BIOS). Strange thing is that it appears totally random. Although I have noticed that it has only woken up either at 1am or 6am.

    That is very odd. Usually disabling your wireless card from waking the computer fixes that issue.

    I have all possible devices set to disable for "allow device to wake the computer."

    powercfg –devicequery wake_armed does not yield anything. In regards to the wake times, I cant be certain that 1am and 6am are the exact wake times. The Event Viewer usually shows some sort of log of particular events at a few minutes after these times.

    Sounds like some sort of recurring event is waking the computer then. Maybe a virus scan or a scheduled defrag.

    My guess is that it's waking itself up to do some scheduled maintenance (defrag, download and install updates, scan for viruses). Check around for that. I generally leave all that on so it takes care of all of it's business in the middle of the night when I'm not using it.

    Check the USB wake option in BIOS (not sure if the XPS 13 has it but I recall that being the problem on another notebook recently)
