When you overcharge the battery on your laptop computer, it can wear out more quickly. As soon as the computer says that you are using reserve battery power, you need to plug it in. When the charging indicator light turns from orange to green, though, you have to unplug it. This means that the battery is full. You do not want to keep sending electricity into it after it is full. Unplugging it will extend its life.
