I eventually had to buy a new computer because it wouldn't hold a charge. I'd have it plugged in, but the computer just wouldn't recognize that it was plugged in. At first, it'd start working again if I fiddled with the cords, but eventually no matter what I did my computer wouldn't recognize it was charging, and it went dead.
My new(ish) computer has started that tonight. Luckily fiddling with the cords words, but this is not a good sign.
