  1. It cannot be done. If you want more video memory buy a new card that has the amount you want.
  2. He can't buy a new video card. That is a laptop.

    As huilun02 said, video memory cannot be changed. Video memory is actually a physical part of the graphics card, as in if you want to change it, you need to change the whole graphics card. However, you cannot replace the graphics cards for laptops. So basically, if you want more video memory or a better graphics card, you need to buy a new laptop.
  4. I asked my computer specialist about changing my graphic card and he said he can't.:(
