Saving energy with PowerTOP 2.0
Power of 2
The PowerTOP tool developed by Intel helps you save power. In version 2.0, it can also handle GPUs and offers advanced tracking features.
If you use both Linux and Windows on a notebook, you will probably notice that the battery lasts longer under Windows, which implies that Linux does not make optimum use of power-saving features offered by the CPU.
This problem occurs most often with increasing laptop age or by distribution installed; however, you can take control of your computer’s power usage through sometimes painstaking and generally very individual fine-tuning. Getting there is much easier if you know the capabilities of advanced CPUs and the kernel. Expert advice on these topics can be found in PowerTOP, developed by Intel’s Open Source Division.
