Old laptop died 🥲 (lemmy.world)

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

No, it's because, in the very specific fault I described, at least one of the caps on the supply line are actually shorted. I don't know how rare it is, I've had it happen on a couple laptops, both Dell now that I think about it
