Looking for some help here with this macbook Macbook A1278 820-2936 , came in after customer used a damaged charger, the issue is whenever you connect the charger with the little power the battery has which is about 17% once you connect the charger it would say 100% , and the battery starts depleting , but not increasing, Please Help me out to resolve this issue, So far I changed The magsafe and U7000 To see if that would've ruled out the issue but no luck.

Machine works good with charger alone (no battery connected)?
Post PPBUS_G3H voltage in this case.

PPBUS_G3H = 11.6V , I was reviewing the board, I found R7052 (CHGR_CSO_N) Was damaged , I replaced it and the machine starts charging with normal Percentage , but it would disconnect by itself for 10 seconds and restart charging again , it did it a few times but if i close down the screen it charges without any interruptions, Any advice Please?

Disconnect BIL and test again.
