Xiaomi Laptop Shutting Off

[Tanklett]

Hi there,

 

In August I got my girlfriend a Xiaomi laptop for her work. Got it off of Kijiji and was working like a charm until the beginning of August. This was around the time we purchased a longer USB-C charging cable. After this point the laptop has began to have increasingly more difficulty staying powered on or even powering on to begin with. If the laptop is used while not plugged in it may shut off randomly and without notice, despite having battery life. It's beginning to get to the point where there is a need to keep it plugged in at all times, for fear of it turning off in a meeting or not saving documents.

 

To be honest I dont even know where to begin to diagnose the issue. If it is battery, how do I go about checking that? Might it be a software thing? I know I can't call Xiaomi, especially since she threw away the box. Any advice at all is great appreciated!

Have you tried not using the faulty USB cable anymore?
