There are no overclocking options on HP laptops as the BIOS doesn't allow it. HP deliberately install a very limited, cut-down BIOS with very few user-configurable settings. This is to prevent the user screwing something up and then expecting HP to fix it under warranty for free.
Furthermore, overclocking causes an increase in internal temperature. A laptop just wouldn't be able to cope with that and, unlike a PC, you can't fit extra cooling fans inside the case. The result would be an unstable system & eventual component failure.
If you want the freedom to overclock you need to build your own desktop PC using retail components, or have a local PC shop build one for you.
