Hi all, new here. I have a Panasonic Toughpad CF-H2 that keeps shutting down suddenly while being used on battery. It seems fine when plugged in, but will shut down suddenly on battery. When checking the battery state of charge it says 78% on 1 battery and 100% on the other. It doesn't seem to matter if I switch batteries or not. I have 6 batteries for this unit and I've swapped them in every configuration I can think of, doesn't seem to matter. I've sent it in for repair, they changed the hard drive, sent it back, but the problem is still there. Now it's out of warranty and I'm stuck with it. Any body run into this issue with these before? Any thoughts on the issue?
