Hello, recently I decided to upgrade Windows on my old Lenovo T420s computer. After updates there is missing two drivers.
Device ID's of them:
First (Base system Device): PCI\VEN_1180&DEV_E823&SUBSYS_21D217AA&REV_04
Second (Software Download): USB\VID_0BDB&PID_100E&REV_0100

Welcome to the forum.
Lenovo does not support the T420s to run Windows 10. You could find the Windows 8.1 on Lenovo's T420s Support page and try them. They should work. Note however that because Windows 10 isn't supported some functions may not work.
