    I've had switchable graphics that did not show device in device manager in the past. I am assuming this is the same instance as the computer does indeed have switchable graphics, as long as long as he has the right device listed.

    I've had switchable laptops for a number of years but never experienced the dedicated not showing in Device Manager. Just lucky I guess.

    For the OP's sake I hope you are right.
    The device not showing up is exactly what happened to me.

    I meant as far as fixing it, wasn't trying to say you didn't experience the problem, only saying I never did is all. Merry Christmas!

    Well, yes, you should check such things immediately after purchase.

    Download the Windows 8.1 Intel HD drivers and the Nvidia driver from Lenovo, Not from Intel or Nvidia or Windows Updates (Hide them).

    Install the drivers in that order, Intel HD first, and then the Nvidia driver.

    When you get the Nvidia Driver installed then you can go to the Nvidia Control Panel and set what Applications use it as default etc. Or Right Click the Application shortcut and select to run with either Graphics Card.

    Other Nvidia Stuff like the Geforce Experience will indicate that you have the latest driver when you don't. It does not matter. Disable driver auto updating here as well.

    There is nothing in my UEFI BIOS concerning Dual Graphics Cards. Doesn't need to as the Nvidia Optimus switching works well.
    It is shown in the Device Manager in Display adapters two entries, in my Laptop HD4600 and GT 740M.

    Thanks for the replies,

    I have attached a picture of my Device Manager (with hidden devices turned on).

    I've also tried the NVidia Driver installation and scanner and they both say that I don't have the relevant hardware.

    I had a look at the link Waffle posted (HOW TO: Nvidia graphics driver can not find compatible graphics hardware | i Gadgets World | innovative Gadgets World) but I can't go through with it because Other Devices/Video Driver is not present in my Device Manager either.

    I'll try reinstalling the drivers, I've contacted Lenovo support in the meantime but I think paying for repairs is not worth it as I'm not an avid gamer and it'd probably be more expensive than buying a new laptop if it's a hardware issue.

    I'll keep ya updated!

    What is that "Other devices" with the question mark in the pic?

    Not graphics related, looks like virtual audio devices which are installed with some video conversion or streaming software. Those have to to with WiDi. Did you try to set that up at one time?

    Just a thought, try this Hardware Troubelshooter from MS Fix It. Also, a guide on trying to view "Hidden Hardware" in Windows. furthermore, I think your problem may be BIOS related, and let's check "C:/Program Files/Nvidia" to see if there was once an install of Nvidia on your system. As for the BIOS, you can accidentally install the wrong BIOS and the PC still working. If I was you, I would restore to the original BIOS by downloading the First BIOS from the Manufacturer site Lenovo. It worked for this one person in the quote below with an Asus Laptop...

    Yes!..
    I contacted ASUS support. They told me to restore default BIOS. Then it's over. Device Manager shows the VGA card and install the card's driver.


    ( ASUS BIOS setup has no settings for graphic card. )

    Here is a sure way to see if your Dedicated Nvidia will work... Go to BIOS and Change Graphics from "Switchable" to "Discrete" Then the computer will be FORCED to see the Nvidia card if it works.

    EDIT:
    I checked a Youtube video and there appears to be no "Switching" option. I would contact Lenovo Support if you already haven't.
