How are you connecting the 2nd monitor? Most laptops don't have dual head video cards.

my lap top has a place to add a regular monitor cable . Ive used it for months usually in a mirrored mode where both monitors show the same thing , by 2 monitors I mean the main monitor on my laptop and add one other .
