what cpu have you got in there, have a look in system, you can replace the cpu in a laptop top, if you any good at such repairs upgrades, i renewed the thermal paste on the cpu recently as i had to put in new fan that was failing, the paste was almost solid, and badly put on in factory, i checked temps before and after, what a difference, i also put in an ssd and an extra 2gb of ram, laptop runs better now than when it was new.
