Change Critical & Low-Level Battery Action
To change the Critical and Low-Level action for the battery for any Power Plan, you will have to open Power Options in the Control Panel > Change Plan Settings > Change Advanced Power Settings. In the box which opens, navigate down to the last item, i.,e. Battery.
Here for each plan, you can configure and set WHAT your Windows should do, after its battery level drops below certain levels. The options for “while On Battery and “while Plugged In” are:

The default for the first is Do nothing and for the second one is Hibernate. You can change it to suit your requirements.
