About a week ago my computer started to turning on just after going into sleep mode.

I've checked common settings related to this problem, such as keyboard / mouse energy settings as well as media server. They all are turned off, making sure that they aren't allowed to wake my computer.

However, even when unplugging all devices and internet, this problem still occurs. I have run powercfg -energy raport and when mouse is unplugged, it does not show any problems. I just don't know what is going on and why computer suddenly started to make this problem... do you have any idea what to do?

I have a batch file with the following commands which i run in these circumstances:

powercfg -devicequery wake_armed 
powercfg -requests
powercfg -lastwake
pause

powercfg -devicequery wake_armed shows you which devices can wake up your computer.

powercfg -requests shows you which processes can prevent your computer from going to sleep. (only this one needs admin rights)

And the last one, the most important for you, powercfg -lastwake shows you the device/process which waked up your computer.

I have a process which wakes up my computer in the morning and it shows:

Wake History Count - 1
Wake History [0]
  Wake Source Count - 1
  Wake Source [0]
    Type: Wake Timer
    Owner: [PROCESS] \Device\HarddiskVolume4\WakeupOnStandBy\wosb.exe
