Hello,
I was working on this board that had liquid damage. I was able to replace the mosfets (pq44) the caps (pc192, pc193, pc194, pc195, pc190) and the resistor pr222, NOW I have power to the board.. There was also damage to the LCD connector on the moterboard,, I was able to use solder and fix the issue.. Now, I'm able to load Windows and use the laptop without any issues, EXCEPT, WHEN I LOAD THE VIDEO DRIVER... Interestingly, the laptop will work with the intel driver loaded anywhere from 40 seconds up to several minutes until it completely freezes and it has to be manually shut down.. If I uninstall the driver I can use the laptop all day without fail..
I originally thought it was solely a driver issue. I tried multiple drivers from the newest to older drivers and the result is the same (yes bios has been updated)..
My question is, if it's hardware related what would be the signal change if any at the LCD connector on the motherboard? More specifically ,, would the installed driver vs no driver loaded have any effect on the LCD data lines that would be noticed at the LCD connector?
