Hi,

First you can try a power drain, check the following video that will show you how to do it:

You can also try with an external keyboard and use it to reinstall the driver in Device Manager.

Let me know if you need something else!

Following this suggestion, I did a power drain and after reconnecting the cable there was still no keyboard functionality. I called customer support over lunch and a technician is going to be contacting me to replace the keyboard.

Ok, send me a PM if you need something else!
