NVidia drivers (Win 8.1 64-bit) on T520

I've just done a clean install of Windows 8.1, 64-bit and am trying to get my display and NVidia graphics chip working properly.  At present I cannot:

-- change my screen resolution (stuck at 1024x768),

-- turn my screen brightness below maximum (blinding when used indoors) or

-- use OpenGL at a normal speed.  It's extremely slow.  Haven't tried DirectX yet.

 

In an effort to get these features working, I have tried:

-- Searching for NVidia drivers on this page.  Result: None is available for Windows 8.1.

-- Downloading a driver from NVidia.  Result: The installer reports, "You must install an Intel driver first."

-- Downloading the Intel graphics driver from same page.  Result: The installer reports, "This system doesn't meet the minimum specifications."

-- Searching for chipset drivers on same page.  Result: None is available for Windows 8.1. 

-- Downloading the Windows 8 chipset drivers.  Result: The installer refused to proceed.

-- Checking Device Manager.  Result: Two display adapters are present.  Originally, both were called "Microsoft Basic Display Adapter" and reported that they were working properly.

-- Running the BIOS update CD image found at same page.  Result: One of the display adapters in Device Manager changed name to "NVIDIA NVS 4200M," and both still report that they are working properly.  (Note that I did this after installing Windows, which I think was incorrect.)

-- Disabling the NVidia Optimus option in BIOS, setting it instead to discrete graphics mode.  Result: Nothing was displayed on my screen after Windows login.  I changed the BIOS settings back.

-- Running Windows Update.  Result: A "monitor driver" update was installed or updated, but it didn't change anything.

-- Running Lenovo System Update.  Result: No drivers were available to install.  It only offered me some updates to things I'd already installed successfully, such as the sound and WLAN drivers.

-- Running Lenovo Solution Centre's "hardware scan."  Result: No graphics tests were performed.  "Not applicable" is displayed instead of "Passed."

Hi,

 

Have you tried installing the Windows 7 64-bit version of Intel Video Driver and NVIDIA Video driver, in this order?

 

There is a good chance that it will work right away, otherwise you can try to run it in compatibility mode, where you get your Win8.1 to act as it was running as Win7

Re: NVidia drivers (Win 8.1 64-bit) on T520

Just checked on support.lenovo.com, where it looks like Intel Video driver has been released in a 8.1 64-bit version for T520. As well is the case for NVIDIA, for windows 8.

 

Reference:

https://support.lenovo.com/dk/da/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t5...

 

Intel HD Graphics Driver for Windows 8.1 (64-bit), 8 (64-bit)- ThinkPad

NVIDIA Optimus Display Driver for Windows 8 (64-bit) - ThinkPad

 

Edit: It is important that you uninstall alternative drivers you have tried to install, and install Intel first, then NVIDIA Smiley Happy

Hi Envergure,

 

I think NVIDIA Optimus Display Driver is enough for both the graphic adapter, you can also check with running ThinkVantage system update utility this will check for all the required latest drivers & application for your system.

 

Hope this helps.

 

Best regards,

Re: NVidia drivers (Win 8.1 64-bit) on T520

Idleman, thanks for your suggestion.  I can't install the Intel graphics driver either.  The installer reports, "Error: This computer does not meet the minimum requirements for installing the software."  I suspect this is because a problem is preventing Windows from communicating with the Intel HD Graphics chip at all, which is why it appears as "Microsoft Basic Display Adapter" in Device Manager rather than displaying the chip's real name.

 

Thanks for pointing me to the Optimus driver.  It will come in handy once I get the Intel problem fixed.

Re: NVidia drivers (Win 8.1 64-bit) on T520

Hemanth, I have run Lenovo System Update 5 again and this time toldit to download the 5 updates it offered, though none of them were graphics-related.  It didn't offer to install any new drivers.  The updates haven't chaged my graphics situation as far as I can tell.

 

Additionally, I seem to have lost the ability to open my BIOS settings at boot.

EDIT:  Nevermind, I can get into the BIOS settings after hitting "Restart," just not after hitting "Shut Down."

Re: NVidia drivers (Win 8.1 64-bit) on T520

Hi Envergure,

 

I am thinking that you have not set the Display to Nvidia optimus option in BIOS, hence you are getting the error while installing Intel graphic (Integrated Graphics mode will achieve longer battery life.Discrete Graphics mode will achivev higher graphics performance. NVIDIA Optimus mode runs as Integrated Graphics mode and Discrete Graphics is enabled on demand. Note:NVIDIA Optimus mode should only be selected if you are using Windows7).

 

You might have installed driver from third party application hence you are not getting the application to install when you are running ThinkVantage system update utility.

 

Check if there are any drivers installed related to Intel graphic or Nvidia graphic, you can confirm this from Control panel – Program & feature option.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

You can force the Intel driver to install using Device Manager's Have Disk function. After that, the NVIDIA driver should install without complaint.

Re: NVidia drivers (Win 8.1 64-bit) on T520

I have gotten the video card working now.  Out of desperation, I tried installing the Optimus driver alone.  To my surprise, this made the NVidia chip start working properly, though the Intel one continued to evade detection by Windows.  The Intel chip started working later for reasons unknown to me, after the computer had been rebooted a few more times and some 3D games had been installed and run.

 

I definitely did have Optimus enabled in BIOS.  As I've said, I tried disabling it earlier, but since that didn't accomplish anything I reenabled it.  I don't believe I had installed any drivers prior to the Optimus one, but I've rather lost track of precisely what all I've tried Smiley Frustrated

 

Anyway, thank you for your help.

Hi Envergure,

 

I have replied the same on the first post only, maybe you had the issue with setting up. However I am glad to hear that your issue has been resolved. Please feel free to post in Lenovo Community Forums if you have any further queries!
