It is worth verifying as parts move / fall-off during rework.

If this current loop is broken (saw this last year with a case on this forum that took ~3 weeks to conquer) - then the charger IC will shut down as it believes that power was applied to the battery leg but then was pulled down to 0 volts. This means too high of a load to support so shut off the battery charging.

Current sense verified.
Waiting for the MOSFET pair to arrive in a month or two.
Will update after swapping.

Q7030 and Q7035 replaced, both at the same time.
No change.
Still Green LED and fan spin.
Gave it about a minute.
Was really starting to get my hopes high too.
Think I'm going to reassemble it to check where I stand on coconutBattery.
Could this actually be the DC in board?
It is a bit worn in the plastic on the sides of the connector.

Well, things changed quite dramatically here.
In the good way.
I have an orange light again!
Got a "parts/wreck" identical mbp with a _working_ battery from a colleague.
Finally I had the possibility to do a sanity check, which would have saved me some time but robbed me from the experience I have gained (More valuable than time itself).
The two Subtel batteries would not charge in the parts machine, at all.
They wouldn't even run on their own without a charger.
Hopefully I still have a warranty with the seller.

mon2: A thousand thanks ("Tusen takk" in Norwegian) for your patience, guidance and knowledge!

Btw: I cannot see an option to set [Solved] in the thread title.
If there is a way, please let me know.
