Hello there, recently I got and a older laptop for spare parts, the thing was not POSTing, suspected was dying gpu (no signal on lcd or external output). It got alive after reheating the gpu so I know the GPU is damaged. Problem is I found a replacement for around 10€ but problem is that original chip have scratched number just a bit: ___M-GE2-B-B1, so I think that original is N11M-GE2-B-B1, and replacement is N11M-GE1-B-B1.
