[comp.sys.mac.hardware] Input Device Freezes

After installing my laser printer I have been having a curious
intermittent problem. Every once in a while when the printer is on but
my HD and my computer are off, I'll switch the latter two on and all of
a sudden all input devices like a mouse, keyboard and tablet lock up. I
literally can't enter anything and have to reset.

I have an extended key board and when this happens all the LEDs on the
KEY/CAPS/SCROLL lock display light up!

Does anyone out there have any idea what is going on?
