My Blackberry 8520 just shut itself down and when I try to turn it back on nothing happens but when I put it into the wall charger the red LED light comes on and a charging symbol but still doesnt switch on.
Ive tried of mulitiple occasions taking out the battery and rebooting it but still no sign of any life?
Any Idea's?

Download the newest firmware upgrade from Blackberry. In addition to a couple of new apps (movie mode and voice recorder), it should take care of your problem. Of course, this is all free.

how to reset the Curve back to factory state (a complete wipe-out). Please note if you just want to reboot the device, you only need to take out the battery.

To reset the phone back to factory state:
Go to Options -> Security Options -> General Settings
Press the BlackBerry Menu key and select "Wipe Handheld" and type in "blackberry"

Device cuts off. Due to whats called battery memory Device thinks battery is spent. does not realize that it has additional capacity. This is due to recharging before battery is fully discharged ie in the red zone. Solution. install a new battery. it worked never had the problem again.

Take out the battery and rub it really fast inbetween your palms, it has not let me down yet, a wierd way, but give it a try,
