Re: Keyboard failure

Try this:

 

Turn off PC by holding down power button.   After it turns off - unplug from wall. 

While unplugged from wall - hold down the power on/off button for 60 seconds (this drains the power from the system).

Plug PC back in and reboot - hopefully, that fixes the issue.

From what I have seen, this is a common problem and the keyboards are fine - Dell does not currently have a solution.

 

Good luck!
