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 πŸ₯²πŸ€š

Thanks for the help guys

You can also use a multimeter to test across the inductor. It should have no resistance / will beep in continuity mode.

Thanks. I guess I was just hoping it would be an easy find and fix. The beep confirmed hope is lost πŸ₯²
