    Hello,

    Do you think it is possible to disable the nvidia gtx 635m (optimus) in my bios?
    It's poorly managed and very hot in my ultrabook (in windows it does not heat... but I'm not in windows... thank's nvidia...)
    And I do not have a menu in the bios to disable it (thank's asus...)

    I do not understand how to do, please help me.

    My bios :
    BIOS 209 in asus.com and my pc is asus s56cm
    Sorry I can not post my bios here

    "but im not in windows ".. ahh OSX . AppleGraphicsPowerManagement needs your cards device id to match to control the speeds.

    ask asus for the option.. they might send u a beta bios. (safer than us messing with it)

    Thank you for your answer. Yes, I have mac os, everything works great except the graphics card ... I deactived to remove the kext but it's still hot and battery is lower.
    I tried to patch my DSDT file but it is too complicated, there is no patch for my pc.

    I'll try to edit AppleGraphicsPowerManagement but there in no kext for gtx 635m and optimus il not compatible with mac os

    I'll send an email to Asus, hoping for an answer ...

    I don't know, msi afterburn does not work with my graphics card, I can not test voltages for flash.
    I think the flash at 0 volt but I'm afraid to kill.

    On my desktop I flash my graphics card for overclock with osx, but I tested with msi afterburn before flashing.

    I have undervolt my laptop vga bios. It seems a bit cooler now. But how can you disable a video graphic? 0 volt is disable but you need to boot? So why not 0 volt when it's the discrete video card?

    It scares me to flash at 0 volts.
    I do not know if the pc will be able to boot.

    in lenovo bios can disable the 2nd card.
    On Asus the menu is hidden :(

    Why are you scared? Isn't this a Phoenix bios? In my bios I have recovery boot block. I can always flash bios.

    It's can be an option rom. It starts with hex 55 hex AA. You can also try to remove the option rom. It should disable the discrete card. That's also the reason when you can still boot at least when you have a recovery boot block.
