Hi Neno and welcome.

Your link says MAXIMUM memory 512MB.

nVidia make the 8400M GT in several versions - 64MB, 128MB, 256MB & 512MB.

Sony have put the 128MB version in your model.

Hi Neno,

I'm afraid you can't do either.

Like most laptops, the graphics chip cannot be upgraded as it is integrated into the motherboard.

You can't add or increase the dedicated memory but this should not matter in Vista as the WDDM feature will allocate any additional memory requirement from RAM automatically.
