Hi, My name is Spencer and i have a Acer Laptop. Now for a year now, my computer would randomly blue screen. not often though. friends told me it was a power failure. But now i am experiencing other problems. Sometimes there would be an X through my battery icon, and it saying "consider replacing your battery". My computer also is been very slow. And when i set it down on a table sometimes it would just shut off. I think my battery is loose or broken. what do you think?
