before you overclock ur lappy. get some thermal paste. MAKE MAKE MAKE sure you are 100% sure about this.
my laptop is current overheating. i havnt overclocked. if i dont prop up the back now with skateboard bushings, thing overheats within 5mins.
Thus, my point being, your insurance if any, is gone as soon as u touch that thing...unless u have a nice amount of money ur willign to spend getting the thing fixed, in which case by all means go for it.
but if u really are ognna do it. make sure u got all the stuff down to prepare
1) look @ temps as laptops have high temps@stock
2) New thermal paste
3) Plenty of airflow. Prop up etc...
4) Check ur warrenty
goodluck =)
