Laptops waking up on their own? Ghostbusters! Or use windows cmd

Today I had a user complaining about self-powering-on laptop in the night. Apart from normal causes (sleepwalking?), we can check why the laptop woke up with two simple commands:

C:\Users\tode>powercfg -lastwake
Wake History Count – 1
Wake History [0]
Wake Source Count – 1
Wake Source [0]
Type: Fixed Feature
Power Button

C:\Users\tode>powercfg -devicequery wake_armed
Dell ControlVault w/o Fingerprint Sensor

And the mystery solved!

Who’re you gonna call? not ghostbusters….
