I am not looking for a long discussion here, I just want to know if anybody ever seen this kind of weirdness before? As a side benefit, perhaps this question will help somebody in the future.
One week ago I installed my coworker's new Dell Inspiron computer onto our Server 2016 domain. The computer has windows 10 pro and Office 365, and several apps that our business has been using for years.
Things have worked very well until this morning when her keyboard stopped working. NONE of the keys did anything even though the shift lock and other lights worked normally.
I tried moving the keyboard to a different USB port, then I replaced the keyboard with a similar model. Still nothing.
The mouse still worked so I used it to close everything on the desk top, which did not help. Task manager also did not show anything unusual.
I opened on screen keyboard ( Start Icon > Settings gear > Ease of Access > Keyboard (near bottom) > turn on top option ("Use the On-Screen Keyboard")
I used the mouse to open MS word, and used OSK to type the letter X into the word document which worked fine. To my surprise, the physical keyboard started working.
I closed OSK and things have been normal for an hour.
This is a very simple solution which I have added to my bag of tricks.
But, I wonder if anyone has ever seen this weirdness before, and if they know what happened.
