Trying to update to windows 10 on T420 but display not compatible

Hi everyone, 

I just did a clean install of windows 7 professional 64 bit on an old T420 laptop, downloaded the various drivers from the lenovo support page.

i have installed the windows 10 uprade assistant, and when checking compatibility it passes everything but the display?

i had the graphics drivers installed and everything seems to be working fine, screen res goes up to 1600x900.

as far as im aware win 10 should install on this machine, id like to get it done while the free upgrade is still possible, can anyone help me figure out why this isnt working?


Thanking you very much in advance!

Hi pixelvandal and welcome to the community,


The T420 isn't on the compatibility list for upgrade to Win 10.  The earliest T series machine listed with full compatibility is the T430.


With that said, Windows 10 will install on your machine, but you might have to play around with the graphics and maybe other hardware in order to get a good experience with Win 10.
