I am running a W10 upgrade of W7 on a Sony Vaio laptop. I have it set to go to sleep when the lid is closed. It does, but will randomly wake up (with the lid closed) and run the battery down if I don’t catch it in time. I typed the following into an elevated command prompt: powercfg –lastwake. Here is the result:
Wake History Count – 1
Wake History 
Wake Source Count – 1

Type Wake Timer
Owner[SERVICE]\Device\HarddiskVolume3\Windows\system32\svchost.ex (System Event Broker)
Owner Supplied reason: Windows will execute‘NT TASK\microsoft\Windows\mediaCenter\mcupdate_scheduled’ scheduled task that requested waking the computer.
I went into task scheduler>microsoft>windows>media center, and found the box to request computer wake up to be unchecked. Does anybody know where else I could look to find a fix for this?
