Saving power with PowerTOP
BETTER SLEEP
Intel’s PowerTOP analysis tool helps optimize power usage and shows you the power guzzlers hiding out on your operating system.
If you dual-boot your laptop with Windows and Linux, you may have noticed a strange phenomenon – the battery lasts longer on Windows than on Linux. When this happens, people normally start tweaking their systems – unloading modules for power guzzling hardware, changing the ACPI settings, and dimming the display.
Recently, kernel developers have started to put more thought into the power situation; thanks to new kernel features, you can reduce your system’s power consumption. PowerTOP is a tool that helps you manage and optimize power usage.
