I have had my ASUS X555L for two years. By the end of one year, I found the battery ran down very quickly - in a couple of hours. It was supposed to last 8-10 hours. Now, it will not run on battery at all. If not plugged in, the screen immediately flutters and you can not access anything. I must have it plugged in to use it. Will replacing the battery help? I have been looking for replacement batteries for this model. I found one, but the review was negative. Does anyone know of a battery that actually works? Hate to have to buy another laptop.
