OT (by a year or so) Electronics/Keyboard Interface Question

Can anyone explain to me what make a PC recognize whether there's a
keyboard attached or not? Is it something as simple as current/voltage, or
does the bios actually have to receive some kind of recognizable signal
from the keyboard? I have a vintage ThinkPad that doesn't like my external
keyboard, yet it works fine with other external keyboards that I've tried.
Mine works fine on another system...

As always, any help would really be appreciated,
