You'll have to get into the machine's BIOS settings to see, but in laptops I've found no options for this one.
The answer so far with the units I've seen is "no". As to adding a graphics card to a laptop, for all the models I've seen, the answer is no. You won't see this on share memory video machines.
I have a HP compaq nx9005 which comes with a 64MB ATI Radeon IGP 320M. Now, my interesting question is, since the graphics card memory is shared memory, can I allocate more memory to my graphics card and so enhance its speed? Or do I need to purchase a new graphics card for that? If I need a new one, a) is it possible to upgrade (because I know laptops are much harder to upgrade than desktops) and b) does anyone have any ideas of the price of an upgrade?
Thanks in advance,
