How to undervolt your laptop for longer, cooler performance

Evan Blass

Most of the PC hacks that you come across are usually in the realm of overclocking or case modding, so it's nice to find an easily-implemented, software-based performance tweak once in awhile that delivers some real results. Well NordicHardware has an article that describes just such a procedure, where Fredrik Andersson steps you through the process of undervolting your laptop. Although as Andresson points out, the terminology is not an accurate reflection of the adjustment being performed, undervolting refers to stepping down the voltage that your CPU requires by several fractions of a volt. The end result of the tweaks that NH guides you through is up to ten minutes more running time and several degrees less heat dispersion, all without affecting the notebook's performance. As with all of the helpful hints that we pass along, this modification is done at your own risk (i.e. don't come crying to us if you break your lappie).
