Computer regularly wakes from sleep.
Powercfg -lastwake shows nothing.
All wake timers are disabled.
All schedules have allow wakeup unticked.
All device wakeups (mouse, keyboard etc) are disabled.
Event viewer shows all the wake times but Wake source: Unknown.
I'm not sure what to try next. The only thing that should wake the machine is the main power button on the tower.
Any more ideas anyone?
Go to Start/Search and type Task Scheduler. Under Actions on the far left panel, click Display all Running Tasks.
There are 4 running but wake the computer to run task is unticked for all of them.
You haven't got the wake on LAN turn on have you?
does the network adaptor also have this as a tick box Pirx? (Just to boost my own knowledge) :)
It really depends on your hardware and what driver is being used; the BIOS setting will be the authoritative one if you want to not allow the computer to wake up due to a network signal instructing it to do so. I will add that I'm not sure this will solve your issue: If that was your culprit you should see your computer wake up even after a full shutdown. Do you have a (Bluetooth or wireless) mouse attached that might be "nervous"?
Hi Pirx - The computer never wakes up from a full shutdown. Only when asleep. I assume that will not be the wake on LAN then?
I have bluetooth mouse and keyboard but their wake up is disabled.
Pirx - Just checked in Device Manager and the network card wake up option is unticked.
