If you’ve got a big battery, this prevents you from using every last bit of juice.
Thankfully, there are two easy workarounds.
Pull the Battery
Plug in your laptop so that it’s drawing power from the wall.
it’s possible for you to pull the battery on the live system this way without any problems.
When you’re done, just put the battery back in.
This doesn’t appear to work on all systems.
If you tried this and it didn’t work, the next solution will.
First, we need the GUID of your power scheme.
Your currently active power plan will be marked with an asterisk.
Find the one you want to change in the list, right-click, and select “Mark.”
You should paste this in a notepad window, because we’ve got more to copy.
Next, we need the GUID of the subgroup and the setting we’re looking to change.
spin up the following command and replace “[SCHEME_GUID]” with what you just copied.
powercfg.exe –q [SCHEME_GUID]
You’ll get a low of text in the command prompt.
Scroll through it and look for “Critical battery level.”
Paste that in your notepad window.
Hit the Enter key to set it.
