Hi,

Got this air board all is "ok". IT starts can work but doesnt charges battery. PPBUS is 8.20V. Already reballed SMC but same thing is happeninc. Randomly PPBUS get normal 8.6V and it begin to work fine, charging but after some time i get issue back.


Any idea?

P.S: No water damage.

Do you always get stable orange light on the Magsafe?
Be sure to use original Magsafe 2 charger; don't waste time using 1-->2 adapter.

Check voltage and diode mode to ground at SCL/SDA lines of battery bus.
Intermitent failure could be caused by bad contacts of battery connector, or SYS_ONEWIRE line at LIO flex connector.
Try known good LIO board/flex.

Hi,

Thanks,

Finally saw that ISL629 had some shit on pins 8 -14. Lift it and there were some traces issue. Reconstructed and now get 8,6V and it is charging.
