yeah.. it can get kind of tricky sometimes trying to find it in the BIOS too--some vendors like to hide the good settings. May want to contact the laptop maker to see if they have a guide or can walk you through it.

One thing to be mindful of when you do disable IntelGraphics. You will be altering the power profile of the system somewhat, so your battery life may shorten and the system may generate more heat. Make sure (and I can't stress this enough) that the laptop has adequate ventilation. Try to avoid things like flopping it down on the bed and such--give it a flat surface as best you can and make sure the air inlet/outlets on the sides are not obstructed--those cheap lapdesk things can go a long ways to extending the life of a laptop. Aside from the absurd things like dropping and dunking---heat is one of the WORST killers of a laptop. It builds slowly over time without you aware of it, and degrades very sensitive components.

Not trying to push Walmart on anyone, but I found a great lapdesk in their furniture section. They were over with the TV trays and it only cost me $10 (price may vary by markets). Many stores have these things...they're wide enough for a 17" laptop with a little room on the side for setting a portable drive or optical mouse. What's great about this one (aside from price) was that it uses velcro to hold the pad underneath. Take off the pad and it's a perfect platform for use on the bed. Should be able to find something similar at places like Target and such. If you don't find them over in the Electronics section with all the other cooling pads, laptop bags, and such-- check the furniture department around the card tables and TV trays.
