Dead laptop from over-volted usb c

[WherEmEweeD]

Laptop is EVGA SC17 Usb-c 3.1 (non thunderbolt) Battery 3.7v 550mah

Ok so i stupidly was hotwiring a battery to charge via my laptops usb-c port, I know i should have used my powersupply or even a usb hub but I was lazy and stupid.

What i did was hooked up the positive to the negative and the negative to the positive (reversing the polarity) did I just fry the laptop by pumping the 3.7v 550mah into the usb-c port?

I immediately unplugged it after the laptop shutdown, the laptop is now not powering on and there is no lights from plugging in the power cable etc.

Is it fixable? There is no smell of smoke and i would assume the laptop has a reverse polarity safety protection.

Any advice is greatly appreciated.

Try removing or unplugging the main battery from the laptop and hold down the power on button to drain everything. Wait a few mins and plug the power supply only in without the battery plugged in and see if it powers on again. If not plug the battery back in again and try again. If nothing then it needs repair as it may have blown a protection fuse or some component on the board.

This would have solved the problem, instead i completely disassembled the laptop and removed cmos and started it up. Thankfully it works 100%. Atleast i got to clear out the dust lol

Thanks for your advice.
