Hmmm the device turned on initially, used it till dead, put it on the charger for about two hours, when i did put it on the charger the first time, i notice a diminished in brightness nokia logo come up and the led was yellowish. When it didn't turn on I put it back on the charger, and the light flashed green I believe, but still wouldn't turn on even with the charger in it. Maybe not enough juice but over 2hrs i'm skeptical, i'll try taking it out when I get back to the phone, and trying again.
