820-00164 No Charging/Run off battery/start off battery.

[2informaticos]

No 3V42, nor PPBUS_G3H on battery alone?
Bad Q7155; did you solder P-channel?

 

[JohnB8812]

Yes no voltage anywhere with just battery. Did replace it from identical donor. Will check traces when I get a chance

 

[2informaticos]

Broken traces around Q7155 then.
Internal diode from Q7155 should automatically generates PPBUS_G3H on battery alone.

 

[JohnB8812]

Hmmm ok will check that when I get back to this one likely Monday.

 

[2informaticos]

Be sure R6950 is OK.
SYS_DETECT_L should be low, to enable battery...

 

[JohnB8812]

True. Didn?t think about that. Will check that as well

 

[JohnB8812]

OMG what a nightmare board haha it was R6950 didn't even think to check it!!! Thank you for reminding me of that 2informaticos you've been a big help as always!
