If you want to go back to stock v2.07 you can do that easily by simply using the Y510p-Y410p_v207_[stock].exe from the first page of this thread.

 

 

Hi. When I tried to downgrade the firmware to 2.07 using Y510p-Y410p_v207_[stock].exe. I got a bios version compare error. 

Is there an option to enable the HD 4600? Because my laptop can not use hd4600 under GT750m SLI. I really do want to unplug the ultrabay graphic card to enable HD4600 which is less power dissipation.

hey,Kwaz. Have you tried the modded bios in the forum? Cuz I do not have permission to download it.

Yes Alienware 18 users can do this. But they have to manually disable the two GPU's and switch to the iGPU. See here:

However, automatic graphics switching AKA Optimus is still impossible due to SLI. Optimus will never work with SLI. Those of you who keep asking need to get this drilled into your head right now. Being able to manually select and use the Intel GPU is not the same thing as Optimus.

Thanks for your reply and correct. What do you mean by manually disable the 2 GPUs? I already disabled the second GT 750 though Computer-Manage-Device manager, but I am unable to use HD 4600. Should I disable both of GT 750? I am afraid I would see a black screen and nothing more.

Thanks for your reply. I disabled sli in nvidia control center and the HD 4600 did not show up. Maybe I should unlock the bios to have a try. I am very disappointed when I ran out of my battery after about one hour. y510p always uses the GT750M instead of the HD 4600. I bought a laptop not a desktop, I need reduce the power consumption when I can not find a power supply.

Hi everyone. I'm new here. My laptop is Y510p gt750m SLI. Recently I want to use the intel 4600 graphic card to save my battery. But I can only install the intel drive with the second gt750m pulling out from ultrabay. When I plug in the second GT750m, I can not find intel 4600 any more. So how can I make SLI and the intel 4600 coexist in my system?
