I play on a laptop too, and there are a few adjustments we have to make.
Your laptop should have a "Fn" key somewhere near the Cntrl and Alt keys. (Disregard the rest of this paragraph of there indeed is no Fn key...tho every laptop I've seen has one). You should notice on the right side of the letter section, there is indeed a numpad that you access using this key. This will work for this np. (For example...my U key has the Fn key of 4. Fn-U = 4).
The easier way, is just to rebind the camera hotkeys (and other). (My current set up is Q,W,E,A,S for various camera angles. W, A are the 3rd person, moveable, Q being first-person. I like these as I am able to quickly swap around views to get a bigger picture, and I don't have to worry about hitting F9 a bunch). You may also want to rebind the camera movement keys. Alt-arrows, Alt-pageup,pagedown, Alt-Home, Alt-End all work for this nicely. Lastly, you might want to rebind your screenshot key.
Of course, now you'll have a different key setup on each of your comps, and that could get confusing. Fn-[key] will work fine if you want.
Lastly, until they make a full size keyboard with the feel of a laptop one (the smaller quicker faster keys) I'll stick with the default ;) (once you get used to a laptop keyboard, it's tough to work with an old style one anymore. Laptop keyboards are very very nice.)
