im planning to swap the mobo and bottom case of g751jl with g751jy and also get the 230w adapter to power it. will it work and will the bottom case fit? Both mobo looks deadly same size wise and have confirmed it from members as well however we do not have much idea about the bottom case. Please advise

well guys, guess what, after hours of disassembling the old 965m mobo and after thermal pasting 980m mobo, ………………………….. it worked, took hours but everything turned out great. So now my specs are i7-4870, gtx 980m, 16gb, 1x 1TB, 1x 140GB, this is so cool. wifi and everything works, the only thing that doesnt work are the 3 USB ports, will have to figure that out since out of the 3 non working USB ports 2 are old ones which were never replaced. Will have to check the 3.5mms and hdmi. Very happy to see 980m in device manager though:)

Well the external dimensions of the G751JL and G751JY are the same but….? Is there a parts supplier that will take returns if it doesn’t fit? Some may be able to help if you send clear photos of your motherboard. I noticed one sight on AliExpress that suggested this. Good luck! Let us know how it goes.
