I have an really cheap Acer Aspire 3680 that I purchased from Best Buy two years ago for $400 bucks or so. The battery really started dying on me in the past few months. At first it would run for around 2 hours - then only an hour - then half an hour. In the past 2 months, it has become a desktop computer. It will literally last 5 minutes unplugged before it dies. Well, until last night. It died. While plugged in. The laptop has absolutely no power - even plugged in. I can't get a light to flick on, a fan to run or anything. It has no power! I'd happily go buy a battery if that is the problem. But if the battery was the problem...wouldn't it still run while plugged it? (I really appreciate any help. I keep all of my financial information, taxes, MP3s and other files on that computer. Even if I can't get it powered up - I need to get those files off somehow.)
