With the memory power off, it reads 3.7v, with it on, the voltage declines to about 2.6, albeit a little more slowly. I assume this is because it is feeding RAM rather than anything.
The old battery, out of the unit, reads 3.55 volts. The only way I seem able to get the 102 booted up right now is with the AC adapter. Even then, it takes a few power on/off cycles, sometimes with reset pressed, and usually comes up with just a partial home screen first. On a new set of batteries, it doesn’t seem to get even that far - just the all-on blank screen. The old battery showed no sign of leakage or corrosion on the board, but what I assume to be part of the motherboard dealing with power (below the battery compartment) did have a lot of corrosion on both sides of the board. Unfortunately, I don’t have equipment or skills to know how to test anything there!
