When the keyboard is powered up (or plugged in), it goes through a self test, and reports the status back to the PC. Normally, a start up dialogue takes place between the PC and the keyboard at this point.
That's fine when you boot your PC, but if you unplug then re-plug the keyboard, the PC will be sent data it's really not expecting, and the BIOS will be very confused.
If you ever want to switch a keyboard between PCs, make sure you leave power supplied to it at all times.
