I don't _think_ anybody's made a laptop in the last few years that 
_doesn't_ have BT, but I may be wrong about that. What make/model is it? 
(Have you tried to find out online if it has BT? [If you can't find a 
manual or similar, look for people selling that model on ebay; if it has 
BT, I imagine most of them will mention it.])

Usually, the PC should recognise that a BT peripheral has nothing like 
that, and either not require anything to be typed in, or accept 0000 or 
1234. The instruction leaflet (usually printed in microscopic print on a 
tiny piece of paper) for the collar will usually tell you what number to 
use, and also what name the collar will appear as when you tell the PC 
to do a scan. (you'll usually have to press a button on the collar to 
put it into "pairing" mode.)

[I say "usually": I have a BT speaker, that worked fine with my XP 
machine; my 7 machine thinks it's a keyboard, and wants me to type 
something on it!]

I _think_ that one means it has found it.

On a laptop, you can often turn it off, either to save battery power or 
increase security. It's sometimes one of the function keys (sometimes in 
combination with the Fn key, sometimes not); often combined with the 
wifi control. It may cycle round all off, BT only, wifi only, both on - 
not necessarily giving all four options, and not necessarily in that 
order. If it's turned off via that route, I don't know if Windows can 
find it. If there _is_ such a control, there'll often be a light (often 
blue!) to show when it's on (and another one for the wifi if that is 
switchable).
