I have an LED-backlit USB keyboard. I recently took it apart to clean it, and after doing so, the LED backlight has started flickering. I assume that this means that I damaged some part of the electronics while cleaning it. Other than the flickering, the keyboard works fine. However, I am concerned that the damaged electronics in the keyboard might cause a short circuit which could damage my motherboard. Is that possible?
Note: the keyboard is not externally powered in any way; it draws all of its power from USB. That's probably obvious, but I'm stating it anyway to be explicit.
