How do I tell if a laptop can use dedicated graphics cards?

I'm looking to buy a laptop, and I want to buy one with a ATI Mobility Radeon 9700 graphics card. How do I know if my laptop can take graphics cards and that it doesn't have an integrated card that I can't upgrade?

Look for any laptop that you can configure at least an NVidia 8400GS. Should be enough to play Half Life 2 at decent settings, plus it's DirectX10 capable so you will be able to run future games.





Here are some computers that feature the 8400 card:


Dell Inspiron 1420


Asus A8


Dell XPS 1330


HP dv6500


and many more





Also, here is a comparison of all cards in the market. You should probably aim for the 'Mid-range' or 'Performance' graphic cards, so if you see any of those cards on a laptop you like, that's the one to pick:

And yes, sadly, once you build a laptop with x graphic card, it can't be upgraded.
Reply:I've never heard of a laptop, which will allow you to install a graphics card. I might be wrong, of course.
Reply:look at the manufacturer's specs. upgrading the graphics of a laptop is most of the time not possible.
Reply:Just buy one with the graphics card installed in the first place. Trying to install a graphics card in a laptop would be a pain.
