Sometimes when I bump my mouse or my keyboard my computer turns on. How do I prevent that?


You can disable all devices from waking your computer with powershell -Command "powercfg /devicequery wake_armed | ForEach{ powercfg /devicedisablewake $_ }".

In cmd, you can run powercfg /devicequery wake_armed to get a list of the devices that are currently allowed to wake up your computer. Chances are you’ll see a couple HIDs (human interface device) and maybe a network card. You can copy/paste these into the corresponding command, powercfg /devicedisablewake "your device here", but that’s annoying.

The ForEach{ $_ } operates a bit like xargs if you’re familiar with that, where $_ is a placeholder for the text in each line of the input (i.e. the powercfg /devicequery wake_armed before the pipe).

When you want to disable it only for the mouse and keyboard do this:

  1. Open the Device Manager
  2. Navigate to Keyboards
  3. Select and default/ using keyboard (usually Standard PS/2 Keyboard), right-click and go to properties
  4. Tap Power-Management and uncheck “Allow this device to wake the computer”: enter image description here

Same steps for the mouse!

Note: This does not work on every device, on laptops there maybe you have to go to the Power Options!
