I wrote this text partly with the on-screen keyboard…
I have the phenomenon that certain keys on my keyboard suddenly stop working. There were no problems all day.
Reinstall the keyboard driver and / or remove the device from the device manager and then restart or use another USB port… - does nothing.
Windows 10 - 1909 (I mean in the 18xx version I didn't have that yet)
The USB keyboard is a Logitech G11 or that of the laptop (old model) is from ASUS.
A while later, however, the buttons work for weeks as if nothing had happened. So the problem is very rare, so I can't see a pattern.
Currently, the keys on the USB keyboard are:
LÖÄ and comma (consequently also the characters that can be reached with the shift key).
It also seems to have nothing to do with switching to another language - because all other characters such as the Z or @ can still be found on the correct key on the German keyboard.
It started with the keyboard of my laptop - here the row no longer works from the A (only ghä # work, but the row above completely: qwertzuiopü + and also the comma that does not work on my connected USB keyboard).
The result is 2 keyboards, in which L and Ö have failed together
Does anyone know of this phenomenon or why?
Sounds like a mechanical cause.
Löä # ,.
Yes, it's strange that exactly these buttons fail.
Did I knock the keyboard out and now it is working again?!
Maybe there's a loose contact inside, in the conductor track.
Years ago we had work where rows of DELL notebooks with the diagonal edc and rfv failed. At their expense, they replaced the entire keyboard plate.
In private, it was once the space and enter key of a not so cheap cherry keyboard that became too loose (sometimes jammed, so that it was permanent pressure)
and the classic that there are jammers when dirt particles get caught (without eating the crooked bun at work)
