Laptop Charger (where in pdx?)

I've come to the conclusion that my laptop charger went and died.

It always was super hot to the touch.

So I need a new one, and in a hurry. Does anyone know of any places PDX/Vancouver that might carry it?

It has a yellow round plug, 18.5V / 3.5A output, 100-240V /1.6A / 50/60HZ Input

How about Fry's? Best Buy? What kind of laptop?

I have a Compaq and a Panasonic charger. One is 19v 3.16A the other is 15.6v 3.85A and you can have them both.
