if you can verify that the car charger is ok, try plugging it in to your computer using the usb cable. the 1412 should charge with the usb cable. if it still doesnt turn on, try and reset the unit,little pin hole on the side.

hi there!

try changing batteries. or try turning it on while charging, if theres no problem when its directly plugged in with the charger, the battery may be dead (especially if its more than a year old and is frenquently used for calls and internet). if its having the error while still plugged in directly with the charger, a local technician is the best here.
