Input: I bought this battery for my laptop which previously had a dead battery and had to be plugged in constantly. I got this new battery hoping it would charge fully overnight and that I wouldn't have to have my computer constantly plugged in anymore. In the morning after completely shutting my computer down and charging it overnight, I checked on it in the morning and after unplugging the cord, it said my battery was completely dead. It was a complete waste of $20.
