laptops are not very upgradeable ,i have the same problem as you i have a laptop that i want to upgrade, the only thing you can upgrade is the ram . I stuck 512mb in my dell inspiron 1300 and it improved performance greatly.
Nope, you're stuck with what you've got on that one. Only a couple of Dell's have upgradeable video and they seem to be the older ones, like the Inspiron 8000/8100/8200 were all fully upgradeable.
