If your green light only comes on when hooked up to power (i.e. car charger unit, usb connector unit on PC) then you have the same problem I had. DEAD BATTERY. Search online for a new battery for the Tom Tom 910 and then search for the instructions to install the battery. That is what I just did today.
Try doing a device update while connected to tomtom home, if that doesnt work backup your device onto your commputer and try reinstalling the software and maps ect onto your device.
