I turned my Pre off last night, which I normally don't do considering I've had trouble turning it back on before. It was at full-charge, I had just taken it off the charger. Now it won't turn on. I've tried removing the battery, several times, and it hasn't worked. I've tried putting it back on the charger and nothing pops up. I'm on house arrest so I can't go to the Sprint store and figure out whats wrong. Any suggestions?
