Board was little liquide damage U5400 area and U3890 area PPBUS_G3H, PP3V42_G3H, PPVRTC_G3H fine. other area very clean

First I have pin 6, 5 of U6100 pulse, tried flash with good rom know 2936-B board (I've backup original rom), voltage after flash was good, after tried with original bios clean me and voltage stable.

Noticed, see Fan pulse after plug charger 1 time and cpu heat, no chime.

The usual corrosion issues: crap under SMC, bad clock chip.

That is fine, there would be PPBUS issues if not.
