This happened this morning. There is a long delay on the keyboard. I have to press and hold a key for a few seconds for it to register.
I have done the following:
1. unplugged the keyboard
2. tried another usb port
3. tried another keyboard
4. uninstalled the keyboard driver then allowed windows to auto discover
5. verified sticky keys was not checked
Also, if I remote into the machine with team viewer my remote keyboard works fine.
Thanks for this help. It works fine except for the following: I still get a distinct 'click' after each keystroke that wasn't there before and before when I would hold down the BACKSPACE key it would continue backward and delete all content that I had typed. Now it just deletes the prior character until you lift and hit it again. So this is a 'workaround' but does not take you completely back to where you were before.
