I wondered - so I tested: An external keyboard does not (usually?) disable* the built-in keyboard.

If there is an intermittent mechanical fault in the built-in keyboard, then that fault will still be in play when testing with an external (USB) keyboard. There is (of course) some value in testing with an external keyboard and/or the on-screen keyboard. Such testing would eliminate or change the amount of flexing/stress applied to the built-in keyboard.

If the issue still happens when booting to a Live CD or to a Ubuntu CD, then we know that the issue is not related to Windows. We would be back to a mechanical fault or a rare BIOS infection or flaw.


*perhaps the built-in keyboard could be disabled via Device Manager. I did not take my testing that far.

I was thinking the same thing: Different controller.

Disable Keyboard driver which is already preent in DevMgr but after plugging in and testing USB keyboard.

Set a System Restore point first
