Fortunately, both problems were solved by using a script, and some built-in battery checks that Windows has. There was the obvious risk that I’d just forget to check how much charge my battery had left, or how full it was. Since it hadn’t bothered me in the past (and this is about 4 years worth of past), I really had zero ideas as to how to monitor battery percentage levels without expanding too much effort. Before this happened, all I ever needed to care about was if my battery was plugged in and charging.
Now that it’s been repaired, I have to keep a very close eye on how much the battery is charged. I had a spot of trouble with my laptop these past few days.
