I am not exactly an expert at this but it could just be from heat. Do you have a multimeter to check if current can pass through it still?

Either way it seems like this shouldn’t be affecting the laptop when plugged in because it is so close to the battery connector and it looks like the traces are related to the battery connector.

Do you get anything at all (battery/power LEDs) trying to run off of the battery? Is it possible that the charge port failed and the battery is just dead now? Maybe check the battery voltage to see how far drained it is.

Current passes through it unfortunately, maybe it’s possible there is a short between coils though. The inductor doesn’t get hot or anything when plugged in.

I think I’ve managed to check the battery voltage, and it seems completely dead (mV).

I can measure 20v on the PCB whe n plugged in.

No fan, no LEDs, etc with either power source. There might be the slightest electrical squeek from somewhere, I will try and find out what …

Even if I don’t manage to fix it. Thanks for the suggestions 👍

  When you saw that 20v on the board I assume that was right next to the charge port? There are often fuses that should be very close to that connector that you can check for continuity on. Usually marked with zeros because they act like a zero ohm resistor.
  
  Even if the fuse is blown that might just be a sign that something further down the line failed but it would be an easy thing to check at least.

    I found the fuse, but it wasn’t blown 🥲 I’ve looked over the board, and watched some repair videos but I haven’t found anything. I’ve called it dead now.
