However when I do replace the batteries the whole unit hard resets. I can’t find a lot of information on the motherboard but there appears to be 4 cells that might be small batteries (or maybe capacitors?) that would keep the memory long enough to swap batteries over. They appear to be soldered in.

Edit: added annotated cells on an image of motherboard.

Anyone know how I can fix the unit? I’d love to contribute a guide for it, and maintain a great piece of old kit.

from what i saw in this video: https://www.youtube.com/watch?v=EHmwHRE4...

Seems hard to take it apart and put it back together.

To be very sure it is the same procedure with the Tungsten T3 model?
