Hi,

My girlfriend's TomTom Go Live 825 is experiencing some issues with charging - in that it won't. Every time it's plugged in, it just says "Charging paused - device too warm". It doesn't matter how cold it is (outside ambient temperature is about +5C), it always says that. It does it from the cigarette lighter socket as well as from a PC.

I've been advised that it might be a thermistor somewhere inside the device - does anyone know where it might be? Is it on the board or part of the battery?

Took it all apart and found what looks like an SMD thermistor (arrowed - first pic). But... this is a guess.



There are no markings on the silk screen next to this component other than S1 and S2 nearby, which can be seen from the pictures.

TomTom are being less than useless. The device is just out of warranty and are asking 105 Euros for a repair. What's making it worse is that they are refusing to refund the Live service subscription that my girlfriend very recently renewed and cannot use due to empty battery. For some reason, it won't work even if the device is running on external power (no choice here!).

TomTom devices seem so poorly made. Last year, her 820 blew up in a puff of smoke (literally). A zener along with a capacitor simply blew up. This is the reason she bought this new one, which lasted just over a year. I repaired the old one by replacing the blown parts (SMDs don't make it easy), which I was using until I got the 407.

Any ideas?

Assuming you are backed up on the web interface, have you tried the 'ultra' hard reset. I only recently discovered that by holding the on button in continuously past the on/off/on/tomtom sound and keep it pressed in you get a complete reset/restore and will need to connect to reinstall maps,etc. Sorry if you already know this.
