Dont listen to these fools, it still should load up, just that performance will not be great.
If it can benchmark 3DMark11, it WILL load up Fallout3http://www.3dmark.com/3dm11/2578967
this is not my system, just search for results of i3-2330M and Intel HD Graphics 3000M
but you MAY need to adjust the amount of RAM the integrated card borrows to atleast 512MB which IS a minimum requirement for Fallout3. This setting should be within the BIOS. When you first turn on the computer you need to hit an F key (it depends on make/model) F1-F12 or just the usual Del key. Can you tell me which laptop it is?
