Last night i chose to make my pc hibernate, but when i woke up 9 hours later, my pc was on and on the desktop with the screens on... And also when i checked the maintenance option to see what may have waked it up, i then saw that it was ticked at "wake up my pc at the pointed time" when i clearly remember removing that tick...
Also my pc wakes up at random times even from sleep mode.
One way to find out what is causing a wake-up problem is provided by the command line. Open a command prompt with elevated privileges and enter this command:
powercfg -lastwake
The last device that woke up the system will be shown
To find out which devices are enabled to wake up the PC, enter this command
Huh, both the network adapter and the keyboard/mouse? That doesnt 't make sense :S Cause i have never been able to wake up my pc from hibernate through the keyboard before, only from sleep with a click of the mouse.
Open Device Manager. There are many ways to do this but a quick way is to enter "dev" (without quotes) in the Start search bar and click "Device Manager"
Expand the list for "Network adapters"
Right-click the adapter to be configured and choose "Properties". There may be several adapters, one for Ethernet, one for wireless, and others like Bluetooth
In the dialog that opens, click the tab "Power Management"
Remove the check by "Allow this device to wake the computer"
Click "OK" and close up Device Manager
I am not familiar with windows 8, but I believe you can choose to have the computer wake from sleep with input from the keyboard only. Mine will sometimes randomly wake from sleep and the culprit I believe is the mouse. But doing this has stopped the problem. I almost never use sleep for different reasons, but that is irrelevant to this discussion.
