    Probably shared video memory, and 0.1 gig is so small its not worth worrying about.

    Video cards have two kinds of memory (dedicated (built onto the card) and shared where it uses some of the system memory to increase it capabilities,

    Again 0.1 gig isnt worth the trouble'

    It's your i7 processor. The Intel HD3000 graphics is using it.

    It doesn't matter. The HD3000 is present and runs until the system determines it needs more horsepower, then your dedicated graphics kick in.

    But what if the IGP is disabled in the BIOS?

    I was under the impression on these dual graphics laptops that you couldn't disable the Intel portion. There'd be little reason to do so, as it is meant to save you on battery power usage and likely heat.
