It was overheating and i have bee trying to open it and clean the fan to see if that would help.
I’ve been used to assembling and disassemble desktop computers, but always scared of laptop unless if it’s just a ram or hard disk issue.

After following all the steps, i was able to disassemble my g72, and was really excited about it. After cleaning the fan, i put everything attached to the motherboard and found out it didn’t sit well. So i disconnected everything on the motherboard and found the cause near the vga plug and sited it well. But unfortunately, when i was trying to connect back a cable labeled “camera” I pushed it too much that it the connector came out of the motherboard and one of the four pins that it was attached to the motherboard with break. But i thought that since is just a camera cable i can do without the camera.
I carefully put everything else in place, after powering on the computer, nothing was showing on the screen, but it is a showing the light and power on sound with the fan working as well.
I disassembled back and check, the only thing that is not connected to the motherboard is the camera cable.
Do you think the problem is something else or can the camera cable stop the screen from showing when power on?
What do you think i should do?
The video cable is well connected.
