I also neglected to say its telling me the battery is 100 percent charged when it isn't.
I've had my laptop fo just undr a year. I've recently been having a problem with my laptop. Plugged in not charging. The classic problem. I called Acer and they sent me a new battery which charged when it was first plugged in. However now when I tried to see if it would work with it on it gives me that sign again. (I know from previous experience it will charge when battery is run to nothing and turned off). I'm confused help.
