Hi my tomtom 910 go wont switch on ], but when useing the charger the little green light lights up and will stil not switch on ive tries the hard resetting and does not work

Two possibilities:
- if someone has used the wrong charger, and connected it to a 12V supply, the mainboard may be damaged. In that case, you need a replacement.
- the battery may be discharged. Even if the green light is on, it doesn't necessarily charge up. Try pushing it hard onto the mount for a few minutes, then see if it will turn on.

Go to:

This site has instructions how to change the battery

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.

Hi i have had the same problem with mine, its a problem with the start up files, plug it in to the pc and also the wall charger, it should then recognise it and then ask to scan and fix the problems once it does that its all fixed, cheers

In general I find these sort of problems can be fixed by the below

If the Tomtom loses battery power it might cease to function with a blank screen but will show a green light when you charge it. The trick is charge it on the mains charger for at least two hours. Then reset the device with a paper clip. If you get no reponse hold down the on button for at least 20 secs and the device will show the Tomtom logo and play a drum roll and startup normally.

Might be the contact of the charger. That's my fault after years of usage
