Hi,my dear @J95! I installed driver then FN+F7 but the Microsoft default single card left.Then i reinstalled driver,the 980m worked. I don't know why,but it worked! I will do more tests tomorrow. thank you for your advise!

@J95,i have installed 3 times as you said,but it still doesn't work.maybe I should remove the card before install win8.1?

thks for your share! @J95.I installed the driver and reboot.then FN+F7,but the 980M was shielded,i dont know why:( i checked the hardware ID，the driver was not be installed on the 980m but on the hd4000. what can i do next?

if your card is not DELL's card ,you need to revise the mod inf first to install the driver:)

i have used the Clevo 980m two weeks with Optimus BUT now I want turn off Optimus with FN+F7 and start only with dedicated GPU. I reinstalled windows from usb to SSD and changed bios setting to UEFI Boot but i'm not sure which mod inf i can use now:( my Config: Alienware M17X R4 i7 3940xm GTX 980M(680M before) 16 GB DDR3-1600 120GB OCZ 500 GB HDD 240 Watt PSU Windows 8.1(now)
