actually, i have read somewhere that few laptops have an extra slot add another cpu. i just wanted to know if xps l502x also has such a provision. thakns for your support.
I have personally upgraded a CPU on a gaming laptop I used to have, but I never heard of a second CPU slot. If you could provide a link to this article I would be interested to read it.
I know of some server style "laptops" that have two physical processors, but those beasts cost an arm-n-a-leg, and not in the Dell XPS category of laptops - basically a mobile desktop, for the price of a server/workstation.
