t460p not detecting GeForce 940MX

2021-01-15, 17:38 PM

Hi All, I have t460p from late 2016. I just did a clean install of windows 10 (20H2), I download and install all the latest drivers from lenovo support page but the geforce 940mx is not showing on the device manager. Is there something I'm missing? how can I check that is not actually broken?

 

Thanks in advance!

Hi Nouan! 


Welcome to Lenovo Community Forums.

 

When was the last time you saw it? Were there any changes or any updates installed before the issue came up? Click on the View tab under the device manager then click on Show Hidden devices to check if the Nvidia driver will appear. If it shows up, uninstall it then restart the computer.

 

If the issue is the same, try running a diagnostic test using the Lenovo Diagnostic Solution: https://download.lenovo.com/pccbbs/thinkvantage_en/ldiag_4.37.0_windows_x64.exe  and send the result code.

Try downloading drivers directly from nVidia.  Just download the "auto detect" from the browser, which will detect the correct drivers you need and the most recent ones.

 

 Lenovo also has some diagnostic software you can download and run. Just search the "pcsupport" of Lenovo for your model, then enter the serial number. There are drivers there also.

 

 Check the Windows Update for the "View optional updates" which usually has driver downloads, not downloaded via the W10 install or the regular W10 update.

 

You might want to  check the "hidden" devices within Windows Device Manager, and see if the 940MX is listed, if so DELETE it or select it and try updating from there.

If it will not update driver from that point, delete the entry, and reboot.

Hi Jews_Lenovo!  thanks for answering! I changed the whole system. I did a clean installation of windows 10 (20H2). Since then I can't see the GeForce 940mx chip. I tried the "show hidden devices" but nothing showed

 

I run the diagnostic tool that you suggested but as you can see in the image attached, it only detects the intel chip

Are you sure that the system is equipped with a Nvidia GPU?  Please check the AC adapter, what type is it 90W or 135W?

 

This page will display the specific list of parts installed in your product. You need to enter your system's serial number.
