Ram channels question?

The laptop I am thinking of buying has an intel hm87 mobile chipset and 3 ram slots. When I google for info about the ram some sites say that it has dual channel ram. I am not sure I believe that. Generally I see motherboards that run dual channel ram and have slots in multiples of 2 and are color coded. Motherboards that run triple or quad channel ram also have slots in multiples of 3 or 4 and are color coded.

My question is if the chipset runs dual channel ram what happens when 3 ram sticks are used? Does it run all 3 sticks at single channel?
