Dead TP2

[twistedfish]

My battery died on my TP2 last night so I put it on the charger and once it I put it on the charger after about 15 minutes it started rebooted itself (just to the splash screen) and the shuts off. I can't turn it on, I can get it to hard reset or soft reset. I am going to head over to the local Sprint store today, but I am curious if anyone else has seen this or may have a solution for it. Before anyone asks, it was not dropped and has no damage, it just doesn't work.

Thanks
