PSP go wont turn on.

I recently got a PSP go. I've had it for a week and not dropped it once, infact i've babied the thing because it's so thin and light i was worried i'd break it(go figure). It fell out of my pocket when i was kneeling and hit a hardwood floor and landed on a blanket afterward. after picking it up and checking for cracks i tried to turn it on and nothing happened. i plugged it in and the charging light came on for a second then went off, and it still wont turn on. Any ideas what messed up and if it's fixable? I think it might be the battery coming loose although without any jewelers screw drivers to take it apart yet with.
