Replacing battery causes a hard reset
I recently bought a Sony Clie PEG-SL10, primarily for the fact that it takes 2 AAA batteries (easy to replace). 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.
