Hi,
I've got a L50D-C with R5-M330 GPU that won't accept it's drivers (screen goes out during driver installation then windows freezes while loading after forcing to restart)

Symptoms of a dead GPU it is, so I've went to UMA conversion but didn't find any schematics/boardview/info anywhere..

After some experiment I've found the solution and decided to share, it was quite simple, just remove the GPU's coil and PWM chip (isl62771)

Mustn't remove PWM CHIP. You just need to remove resistor from VCC pin this chip. (if it is here), or cut VCC trace

I prefer to salvage the isl chip rather than salvaging a resistor or keeping it useless on the board

Thank you for your replay,,
