It was broken before so no surprise plus you learned a valuable lesson about removing power and batteries before beginning work.
I was messing around with an old laptop I had been given , the screen is broken so I took the whole thing apart so it was just the basics. Hooked up to a hdmi I installed a New operating system onto it . I had it working fine all evening until I decided to try my luck and plug in a different laptop screen I had lying around (realising that it 99% wasn’t going to fit but worth a try) . Rushing around I was trying to plug it into the motherboard and realised it wasn’t going to fit but I was actually trying to plug it into the wrong side of the connector which caused a few tiny sparks , after that I realised that the battery was still connected and was still plugged in on charge ! ![]()
Pretty much as soon as the small sparks happened the orange charging light went off.
The laptop will not power on or show any means of life , no lights no fan , no noise what so ever . The charging power supply still works As tried the light is still on the brick.
So annoying . A good little project was going so well until this happened.
Have I totally fried the motherboard?
Any help would be much appreciated.
Cheers
