Water Damage Repaired, Later Doesn't Charge

It’s been about a year and a half since liquid was spilled on the keyboard and it no longer powered on. It was repaired by a reputable shop but after leaving the laptop for a few weeks recently, the battery is at 0 mAh, the magsafe lights up orange, but battery is “not charging”

Did all the SMC resets and stuff, which actually for whatever reason is what made it start showing the orange light instead of green. The battery was replaced at time of repair.

My question is, charging circuit, a fuse? What is likely the issue, as I’ve only repaired iPhones. I can just sell it and let it be someone else’s problem, or if its not too hard to trace and re-flow or jump maybe I can do it.

How about installing this gem of an app so we can see what's happening CoconutBattery. Take a snapshot of the main window and post it here once with the MagSafe connected and once disabled. Adding images to an existing question

Added a couple of pictures, it was saying 0% plugged in, not charging. Now it says 100% but shuts off instantly when adapter is removed.

@keenor what did the repair that was made consists off? Post some good pictures of your logic board with your question. Let's see what we can find out. I don't think a fuse is at fault here but a sensing resistor is a possibility

There are two sets of MOSFET’s one is set to allow the MagSafe to charge the battery the other set is setup to power the system when the charger is removed. The voltage comparator logic would be the other possibility. Clearly, the battery is holding the charge so it’s only the discharge part of the circuit that needs repair.

This will need someone with deeper skills as well as tools, and access to the needed parts to repair. The other direction is to just replace the logic board.

Even though it was showing 0% sometimes?

I'm not sure what your thoughts are here. The battery charge/discharge logic is the focus. Liquid damage can be nasty! If not properly cleaned at the very get-go can haunt you later as in this case.
