|The term CARD is frequently mis-used. Most laptops, probably including yours, have onboard video - video built to the mboard. A video CARD is removable and plugs into a slot directly connected to the mboard. You probably do not have a video CARD. |
"...it has "expandable memory up to 1024mb" .."
That means you can go into the bios Setup and change the amount of ram that is shared with the onboard video so that it shares as much as 1,024mb = 1gb.
Since you probably have 3gb of ram installed, that setting is probably set to 128mb right now.
