|I decided to upgrade the windows install on this computer to Windows 10 from Windows 8.1|
Everything seemed to work well... the numbers on the physical keyboard were working.
Then, they stopped
I updated drivers and googled the heck out of the issue
Numbers 1,2,3,4 and 7,8,9 and 0 do not work on the physical keyboard but will work on the touch screen keyboard and will work if an external keyboard is plugged in.
I've since restored the tablet to factory defaults and did all the windows updates and all of the appropriate Lenovo drivers.
still no numbers!!!
