I purchased the new logic board with the HDMI & expanded memory. I have been using it for a little while. I ran into a problem shortly after installing it into my GameShell, where the battery indicated fully charged, but would shut down the GameShell if the USB was disconnected. I assumed the problem was with the battery and since I had purchased two additional batteries previously, I swapped out the battery and it seemed to resolve the problem. Most of the work I do on the GameShell is with the USB connected so I can access it through ETH-USB, so I didn’t see the problem again until last week. The new battery was giving me the same symptoms. It showed fully charged, but if I disconnect the USB, it immediately shut down! I then decided to test it by swapping back in the old logic board. IT booted fine and showed about 3/4 charged but remains running whether USB is connected or not. The problem has to be with the new logic board.
