So i got one more g62 on desk. Here whats up, it was given to me as black screen, reflowe norhtbridge and machine starts as normal, so in order to fix it
properly i install "new" (used) rs880m and now laptop is black screen again but i can here entering windows and i can even put it to sleep and boot it up but no image on internal or external disply. So anyone have bios just for try or i will need new nb again note this is version with discrete gpu.

I guess you need to reflow again or the used IC you put in was already bad.

Unless you changed GPU for a different model I don't see why you'd need to change BIOS.

Changed with same NB 216-0752001 my luck will be that chip came to me dead ,one question where do you ordering gpu nb sb chips this was from ebay but turns out it didn't do that well.
