IBM Model M2 keyboard error codes (LEDS)

I have an IBM model M2 here which when plugged in, the Num lock and 
scroll lock leds go on, and the keyboard refuses to do anything. I 
notice that SOMETIMES the Model M I have here does the same thing 
(num+scroll on, no response) for a few seconds, and I'm GUESSING it 
might be something like the 5v line can't supply enough current to run 
it properly at startup, but it usually starts working after about 3 or 4 
seconds; the M2 does not.

Any idea what causes this, or whether it is fixable?
