battery board was corroded so I didn't bother plugging it in. there was corrosion around Q7065 and Q7401. haven't replaced anything yet. board refuses to boot with by-3200 cable, not sure if the battery charging circuit would stop boot or if there is another underlying issue. sits at 20v 100ma. I did try plugging a battery in and it went up to 500ma so it appears to be charging? not sure what to check next.

Check diode mode to ground at all big coils of the board.
Liquid sign near Q7401 is not good at all.
PCH could be easy damaged...
