Is there a way to upgrade a processor on a laptop?

I have a Dell XPS 17 L702X. Processor is Intel® Core i7-2630QMQM CPU @ 2.00GHz. RAM is 8 GB. System type: 64-bit Operating System. I believe my graphics card is the Nvidia GeForce GT 550. It's a laptop.

I am having issues running the Day Z mod smoothly. I can run almost any game I play on the highest graphic settings. I play WoW, Starcraft II, League of Legends, and more all on the highest graphic setting and it runs smooth as dairy(it sounded right at the moment). I have fiddled with the graphic setting numerous times, and even on Low and a much reduced resolution I am still getting lag. What should I do? Is there something I am doing wrong? Please help, thank you.
