Laptop CPUs

I broke down a few old laptops for the first time. I'm not sure about the CPUs.... I've not seen it discussed, and I couldn't find any clarification on laptop cpus on the buyers section. I got excited when I found a 486 until I realized that it wasnt like the ones from desktops. It is soldered onto a small board. Do they need to be removed from the board or sold as is? Does it still sell for the same $? I have a pic, but it won't post. Says I'm to new. Thanks for any help, Adam
