I think I might have fried my motherboard, or at least some components.
I was trying to disconnect the battery and stupidly used a metal tool. There was a tiny spark and now sure enough the laptop won’t power up, whether it’s plugged in or not. No leds or nothing.
There is normal voltage coming from the AC adapter thru the power lead to the board. There also still seems to be voltage coming out of the battery.
Has anyone done this before and fixed it?
Is there a fuse or something? Or componentry I should be looking at first?

I'd highly pick a fried mainboard. Nothing you would be able to do except send it away for repair.

If you are skilled in SMD soldering and PCB level repair rework, it's probably fixable.That being said, if you have those skills you probably wouldn't be here asking this, and if you don't have those skills, it's probably in the "not economic to repair" category. Depending on the age and specs of the laptop, replacing the motherboard _might_ be an economically viable repair. Many notebooks use non socketed CPU's in these days that mean replacing the main board is also replacing the CPU which whacks the price up. I looked at a notebook for  someone last week where a gate driver in the power circuity had blown, because it had the CPU soldered on, a replacement board was nearly $1k NZ new from EMPR, or $3-400ish for boards of unknown provenance ex china. He got a new laptop.
