Depending on your laptop's ventilation solution, it might not actually be designed to operate at load with the lid closed. I know that some of the big, bulky Asus laptops require the lid open for full ventilation. An alternative, if closing the lid w/ power options as Jeff advised sends your temps through the roof is to simply use the windows+P shortcut to ...
