[solved]PPBUS_G3H low voltage 820-2850 not charging fixed via Q7055

[appleonarim]

Hi Everybody

820-2850 is working with charger , shows battery and charging but its too slow ( in 40Min. %2 charged). When i checked voltage see PPBUS_G3H is 11.8 volt but must be 12.8V. Louis wrote few times 1or 2 volts is missing on PPBUS_G3H its cause from SMC but i want to ask again any where can i check before SMC? ( I checked R7051,R7052 and R7005 its fine)

I guess is a bad battery try with a known good... What OS report about battery... "Replace Now", "Service Battery"??

I tried known good battery nothing changed OS report condition normal for battery.

Could be a bad Q7055, did you run ASD, does it reports some sensor issue??

Classic Q7055 issue, replace.
