overclocking?

the required options are usually restricted in the bios so you cant, it is on mine anyway, the latest XPS/other gaming laptops may be different however.
 
the only thing that would be worth overclocking on a lptop would be the video card, if it has one, or the integrated graphics. Overclocking the cpu will probably just cause too much heat for the system to handle, most lappys get hot enough as it is, programs like ntune may be of use if your laptop uses an nvidia chipset
 
clockgen is an OS based clocking tool that could be used in the absence of BIOS options, but as stated above its not worth the extra heat which the lappy cannot remove and you will end up frying the components.
 
It is fairly easy although you wont get a big clock because of the heat.

I got a 1.6 pentium M to 2.1 before but I did a lot of mods on it.
 
This is well travelled ground....

Laptop bios' completely lack overclocking options, and laptops just aren't designed to cope with the extra heat/power needed. There were a crop of people pin-modding 400mhz FSB Pentium Ms in the high-end Dells a few years ago, but that was an exploit rather than manufacturer design.

A couple of machines these days have 'on the fly OC' buttons that will raise the multiplier at the touch of a button (MSI have a few out).

But really the only thing you can OC is the graphics card, and if you own a three year old Dell Inspiron like I used to, not even that without flashing the vidbios!

ClockGen etc. don't work because laptop motherboards are so proprietary.
