So last night I had my blackberry charged about 3/4 of the way, and when I went to check my messages, it was off. I tried turning it back on but nothing. I pulled the battery, nothing. It's happened before but usually I'll go home and plug it in and it turns back on. But I went home and plugged it in, and nothing. No red light either. I tried plugging it in my computer too, and nope. How can I fix this?!
