Hi again frigg50.
Your notebook typicly comes with 512mb ram with a max capacity of 2gb.
The upgrade procedure is in the manual here
in pdf format. See Hardware Upgrades>Removing\Inserting Memory Modules.
How much main memory borrowed for graphics is controlled by the mainboard chipset. You can often adjust this via the bios setup menu in the "main" or "advanced" menus or sub-menus. How to enter the bios setup menu and navigate is here
Also, by eliminating XP's default eye candy, such as menu animation, menu fading, visual styling, etc, you can get a little more of that main memory back.
The real question here is how far you want to take it. Maxing the main memory, dedicating max video memory in the bios and tweaking xp itself to use less main memory for other things will definetly help, but there's no gaurantee when it comes to really "intense" graphics usage on a laptop, especially when gaming. You are also limited to a 1024x768 screen resolution. Nothing you can do about that. There are also apps\games that require a seperate dedicated video card found in desktops. That is nearly always indicated on the box.
