    How do I make my macbook pro to work with integrated GPU only?

    As title says my dedicated GPU AMD Radeon HD 6750M died and there is no point in replacing it since:
    - there is no authorised service provider in my country. there is no apple here
    - unauthorised service asks for $700 and gives 2 weeks warranty only.
    - there is no guarantee it will work long enough(2-3 years)

    So I'm looking for ways to make it work on integrated Intel HD 3000 GPU.

    Currently I've found a workaround. When starting macbook pro it shows green and red lines and hangs with grey screen. While hanging fans start to make noise. After overheating macbook pro starts with no green and red lines. Assuming it uses integrated GPU. It loads OK. Then using gfxCardStatus app I can force it to work on integrated GPU only. This step however often leads to hanging of macbook. If it didn't hang it works ok until I put it to sleep or restart.

    Tried to move kext files and resetting the SMC which didn't help.

    Are there other workarounds to make it work on integrated GPU?
    How to make it start with integrated gpu without overheating?
    Is it possible to remove the dedicated GPU so macbook doesn't see it?

    Thanks in advance

    Nope. It's soldered.

    Try removing the AMD drivers via single user mode.

    Radeongate has hit 2011 MBPs throughout the whole world. You're not alone.

    Another GPU Dedicated Machine EPIC Failure !

    Same Dilemma I am in, as i am thinking about upgrading to a 15" rMBP to go for a Dedicated GPU Mac or not. Have been warned about this same phenomenon by a lot of people here...If Longevity is the criteria 5 Years+ Do not go for a GPU Dedicated Machine. Period ! Tried and Tested too often. GPU dedicated Machine do not last more then 3-4 Years with heavy use.

    Coming Back to this problem. I understand your pain my friend I don't wanna scare you, but its good to throw this Mac away now...same thing happened with my SONY VAIO Dedicated GPU from Nvidia Died down. Got it repaired was given a warranty only of 2 weeks. Took the chance within close to the 2nd week. The Mother Board went complete useless had to chuck it finally had become piece of Trash to be sold in Junk according to its metal weight.

    As I've said I've already tried removing drivers(kext files) which didn't help. All I got was a blue color tint, bugs and crashes. Assume that the same kext file used as driver for both GPUs.

    If you do any more fiddling around with the Motherboard you are sure on the way to completely Brick your Already ageing and maybe died Machine in to further more pieces...It is beyond repair now, I am telling you...Even if someone gets it working...no one can guarantee how long will it still keep on working ? BTW how long was it with you...how much time have you used it ?
