"""This code is meant to run in the background to monitor the internal temperature and battery of the PC, giving 
warnings to the user, and shutting down when critical levels are met.

note: I couldn't use a list of strings with low_battery power for some reason using 'if battery in list'.

Also, since I only have a virtual machine for linux, inxi was not able to track the temperature of my actual pc. So
the first part is purely guessing based on the examples on the web. If ti does not work, the field number might be wher to look"""
