|Laptops do not overclock well, even when it is possible. They lack everything necessary for safe and effective overclocking. Overclocking means more heat and many laptops run hot even at stock speeds. The manufacturers are well aware of this and usually do not include in the BIOS the settings that are necessary.|
It is best to confine overclocking to home-built desktops where you can control the specifications and quality of the components used.
