When using the native laptop keyboard, or another BT Logitech K480
keyboard the problem is not there.
Well, there you go, you (most likely) have a problem keyboard. You've
already done your tests and found where the fault is.
The question is, do you replace it or try and fix it (which may not be
possible). I see it's a programmable gaming keyboard model, that would
make the electronics a bit more complex, with more possibilities for
failure. Also more possibilities for reprogramming its behaviour.
Has it been kept clean, any spills? Does it get a lot of bashing in
games?
Is it plugged directly into the motherboard, or go through a hub. With
a complex keyboard, especially an illuminated one, it would use more
power than a standard keyboard, and a shared hub might not be powering
it adequately. Some motherboards use a hub between it's own sockets.
When you see USB sockets bunched in pairs as a one-piece block, those
pairs may be sharing a common power supply, sometimes even more sockets
might be shared together. Try the keyboard just by itself.
