powertop - program to analyze power consumption on Intel-based laptops.
Install this in Ubuntu,
$ sudo apt-get install powertop
$ sudo powertop
powertop is a program that shows the power consumption on Intel-base
laptops and makes suggestions on how to extend battery lifetime.
More info: 1) http://www.lesswatts.org/projects/powertop/
2)
http://manpages.ubuntu.com/manpages/natty/man8/powertop.8.html
Note: I only tried it with "Deb" package derivatives.
Ex:
arul@arul-desktop:~$ sudo powertop
[sudo] password for arul:
PowerTOP 1.13 (C) 2007 - 2010 Intel Corporation
Collecting data for 5 seconds
PowerTOP version 1.13 (C) 2007 Intel Corporation
P-states (frequencies)
2.00 Ghz 4.1%
1200 Mhz 95.9%
Wakeups-from-idle per second : 135.3 interval: 10.0s
no ACPI power usage estimate available
Top causes for wakeups:
49.4% (125.0) PS/2 keyboard/mouse/touchpad interrupt
13.1% ( 33.0) [Rescheduling interrupts] <kernel IPI>
12.4% ( 31.3) [i915] <interrupt>
9.3% ( 23.4) plugin-containe
9.0% ( 22.7) [kernel scheduler] Load balancing tick
2.8% ( 7.1) firefox-bin
Suggestion: Enable the CONFIG_PM_ADVANCED_DEBUG kernel configuration option.
This option will allow PowerTOP to collect runtime power management
statistics.
