G46VW not booting. Just power light and hard drive spin up.

Okay im going to make this sorta short. Had a G46 for a long time wouldnt charge anymore after 2+ years so I let it sit. Screen gets cracked so I replace it with a 1080p 14 inch. Friends dad is an electrical engineer and decides to fix the power jack. Power jack gets fixed but keyboard ribbon cable is damaged.

Order a new one from Mouser electronics. Put new ribbon cable in on my birthday. boot up laptop. Works like a charm everything works including touchpad. I turn the laptop off and button it back up putting screws in the right places and everything. Turn it on and all I get is a power light and a hard drive spin up and flash but nothing else.

No screen no backlight nothing works besides turning it on and off and fans.

I did the bios trick by putting the new bios file onto the drive from my desktop and put it back in the laptop. Hit control + enter on bootup and nothing.


What is wrong with this thing? How could us doing weeks of ****ing with it + me putting it back together make it finally do this???

If its not one thing its another. All I want is a working laptop again

 

You might have put something in incorrectly or shorted something out. Take the board out, test it, if it still works then rebuild the machine carefully.

 

Have you taken it back apart and checked the seating on the ribbon cable. If worked normally before you put it all back together its possible something came loose during the reassembly process.
