Undervolting a Laptop

With all the PC Modders out there cranking up the speed and power of their machines by a few percent, it is nice to see a tutorial on how to save power without losing much performance, and that is exactly what the tutorial undervolting a laptop looks to accomplish.

Because CPUs are mass-produced, the voltage is set to a stable level that will suit all samples of that particular CPU. Everything from CPUs with “Friday Afternoon Syndrome” to real overclockers. There are lots of CPUs on the market that can be run at a lower voltage than what they are specified to. Especially the kind of low power consuming CPUs found in laptops. You’ll be surprised when you see the results of undervolting your CPU.

In this article we will look further on how you can undervolt the CPU of a modern laptop without losing performance or stability.

Our test-system is an Acer Aspire 5021WLMi which appear to be a good computer to undervolt.

A very cool article on those that are hardware savvy and want to add another half hour of battery life to their machine.
