Hpg60-120us Gaming help

Hey, I have that laptop and I like to play games but I travel alot... I get VERY low frames per second on every game I play (Except Diablo II and STO for some reason)
It is starting to cause problems as I am now playing a few shooter type games and as you probably know if I lag I can't aim and I die. Anyway, is there anyway to speed up my craputer?

(Yes I know a gaming Craptop(Laptop) is a contradiction but I don't care)

Thanks!
