I tried to start my laptop earlier, only for nothing to happen. It won't start on battery or when plugged in (it can run without a battery when plugged in). The battery does seem to be dead, and so is the 3V CMOS battery.

I opened it up and noticed a circle visable on one of the inductors. Hopefully you can see it in the picture.

Could this be the problem, or is that normal?

Update: I've tested some suggestion and watched some repair videos, but I found nothing. Goodbye old friend 🥲🤚

Thanks for the help guys

Check that the power brick is outputing the right voltage? Also, remove any component that you can and after each one try to start it. Sometimes a bad drive or memory dimm can keep everything from working.

Great advice, but unfortunately I've checked. 20V from the supply (measured on the laptop PCB), everything removed except the ram because I only have one compatible stick - I did swap the slot though.
