I have a liquid damaged 820-00164-a board here
computer boots, does not charge battery.
no green/orange light
was not booting, cleaned up r7005 area where there was corrosion, also corrosion near f7140
f7140 showing .3ohms may be hardware resolution
ppdcin_g3h_chgr 14.8v
ppdcin no short to ground
isl6259 area untouched by liquid
ppvbat_g3h_chgr_r Stable at 8.6
chgr_bgate not stable stable at 8.6 for about a second then falls off and takes about 10 seconds to bee stable for another moment
am i looking at a dead isl?
or am i possibly gettting bad info to the isl making chgr_bgate jumping up and down?
