|Kind of a long story but,|
The touchpad went out on my brother in-law's laptop he bought from my company 1.5 years ago. I took the machine apart and found a Burnt Chip. Removed the cable that connects the pad to the MB and reasembled it.
It turned on, but no screen, and the fans stopped after a couple seconds of running.
Took it apart again and found the backlight cable got partially severed by the frame when reasembling. (4 out of 6 wires were cut)
I tried splicing the wires together but still no video output and the fans turn off after 5 seconds.
Could the motherboard have been damaged?
