As long as I remember to turn off the switch, this is guaranteed to prevent the computer from waking up while in hibernation. I have given up on hunting these down, so instead I connected the computer and monitor to a power strip with a switch that I use to remove power from the computer once it has started to hibernate. Maybe I have just not found and disabled enough things that can cause a wakeup. Update Įven though the frequency of unwanted wakeups seemed to be much reduced by the above measures, they sometimes occured anyway. If it is not, I will continue to run the above commands again to see if any new wake timers have popped up. I hope that this will be the end of the computer waking up all by itself. There are no active wake timers in the system.Īnother way of checking for tasks that could wake up the computer is to run Power Shell and the following command: PS C:\Users\Per> Get-ScheduledTask | where I clicked the circled Deactivate (“Inaktivera”) button to disable the scheduled updates and after this the powercfg /waketimers gave the following response: C:\WINDOWS\system32> powercfg /waketimers In it I was able to dig down to Media Center and disable its daily checking for updates, see screenshot below (again, it is from my Swedish installation, but I guess it is it trivial to figure out how to do the same thing in an English W10). I do not want the computer to wake up to install updates, so I found out that scheduled tasks can be controlled by “Schedule tasks” (or “Schemalägg aktiviteter” as it is called in my Swedish W10 installation). This did give a useful hint since it told me that mcupdate_scheduled was set to wake the computer up at 15:46:51 the next day, presumably to update Media Center.
Reason: Windows kör den schemalagda aktiviteten NT TASK\Microsoft\Windows\Media Center\mcupdate_scheduled som kräver att datorn aktiveras. Timer set by \Device\HarddiskVolume2\Windows\System32\svchost.exe (SystemEventsBroker) expires at 15:46:51 on. Then I tried the following: C:\WINDOWS\system32> powercfg /waketimers In my case the response unfortunately says nothing about why the computer woke up, which seems like a major shortcoming. Turning all of these off did however not stop the computer from waking up.Īlso, a recommendation was to issue the following command in a cmd window to figure out why the computer woke up: C:\WINDOWS\system32> powercfg /lastwake I did some googling and found a number of things that could be the cause, like the mouse, keyboard or network interface being able to wake the computer up. Here is another issue I have been having since upgrading to Windows 10: I often find that the computer has woken up from hibernation, which is of course irritating since it unnecessarily consumes power.
