Intel offers Linux battery analyzer
Intel has announced the availability of PowerTOP, a program that collects power-consumption data from your system and presents an overview of how well your laptop PC is doing in terms of power savings. In addition, PowerTOP indicates which devices and software components are the biggest offenders in slurping up your battery time. PowerTOP updates its display frequently so you can see the impact of any changes. (www.linuxpowertop.org)
