Disabling critical battery action

 I have an old laptop with an almost dead battery, which I always use tethered to a power source, mostly as a media device connected to my TV. Occasionally, I need to move it, and if it's open, Windows realizes that the battery is very weak and decides to hibernate, as that's the default critical battery action. This can become very frustrating. The good news is that you can easily address this issue using Windows' powercfg command.
