Question Keyboard on Dell E6400 will not work but touch pad does. U

[Charlesf]

Ah, here I can say more. The machine E6400 has worked for years on W10 after upgrading from W7. Now the keyboard won't work but the touchpad does. USB KB works OK and Bluetooth mouse also. I think it must be a driver issue and Dell say they don't support W10 on this machine. They were OK until I had major software problems and had to use ePSA recovery. Can anyone please help? I need this for my Software Defined Radio. I remember having to use Bluetooth drivers from another Dell laptop because there was not an official E6400 W10 driver
