I would like to play videogames on my laptop, but it only has a 128MB dedicated video memory, and on the gpu settings it says that there is a total available graphips memory of 1759MB, it also has 0Mb of system video memory and 1631MB of shared system memory, my cuestion is: how can I increase the video memory from 128Mb to 1GB or more, without adding other hardware to my laptop?, please its urgent

Sorry, your laptop's not a gamer. The amount of graphics memory isn't the problem, the weak Intel 4500MHD integrated graphics chip is the problem. It's fine for HD video & "normal" tasks, but it's not good for modern gaming. Here's a few clips from a recent review: "System performance was great in nearly every category except gaming." "Gaming was limited to past generation games, or heavily tweaked games that wouldn’t task the system that much." http://www.notebookreview.com/defau... Here's a review of the Intel 4500MHD integrated graphics chip: "the performance is just on par with the entry level dedicated graphics cards and therefore not suited for demanding games." http://www.notebookcheck.net/Intel-... If you have a specific game in mind, try running this to see if it will be playable or not: Can You Run It? The bottomline is, if you wanna play games with a laptop & play them well, you need to buy a gaming laptop. They generally cost considerably more than your $900 BestBuy special, but the Alienware Area-51 m15x at only $1100 is a hell of a lot more machine for the money: http://www.alienware.com/products/n...
