PowerTOP is the open-source Linux utility that's largely developed by the Intel Open-Source Technology Center for revealing information about tweaks that can made to power-tune the system, indicate current power consumption rates, and other information to help prolong your Intel Linux system's battery life. The original tool has been around for about five years.
The key improvements of PowerTOP 2.0 include enhanched diagnostic capabilities using the Linux kernel's perf framework, a new tab-based UI that reveals more detailed information than the original PowerTOP, and advanced reporting capabilities for offline analysis. The reports now support HTML5 as well as CSV.
