If you require any more information please dont Hesitate to ask thanks Your upgrade options with a laptop are very limited. You might be able to add some more RAM and a bigger hard drive and thats about it.Hey, it's stix!
Nice to see you here buddy!
Unfortunately deerpark is right - more RAM is a good choice, 1Gb would help for BF.
Your CPU is FINE, your graphics card is a bit dated now but there's nothing else you can do for it.
