Apparently, it's a common fault on the Tom Tom 910 for the rechargeable battery life to diminish dramatically after a year or two and my wife's was no exception.
Replacement batteries are available on the internet along with the torx screwdrivers to fit them.
Unfortunately it appears that the first thing that is fitted into the chassis is the battery and consequently it's that last thing to come out. First, off comes the casing, then out comes the GPS antenna board, then the main circuit board, then the hard disc, then the screen and finally the battery. Along the way there's a couple of wires and a couple of ribbon cables to disconnect.
Then the whole lot goes back in, in reverse order. About an hour and ten minutes in total.
The thing's on a 24 hour charge now, then everything should be good as new.
All credit to whoever designed the thing, packing so much into to such a confined space must have taken a good deal of thought.
Anyone else ever need to do the same, drop me a PM and I'll let you have all the details and a few hints to make the job easier.
