Longer Laptop Battery Life under Linux

ThinkingInBinary writes "Want easier power management and better battery life on your Linux laptop? Try powermgr, a daemon that automatically (or manually, if you choose) switches your system between power "profiles". It has support for ACPI (of course) as well as Asus, Dell, IBM, Omnibook, and Toshiba extensions. It can control CPU governor, screen brightness, wireless card, laptop mode (via services), runlevel, services, and more, and can switch based on AC adapter and battery state, load average, temperature, running processes, and more. Tests indicate that it can prolong battery life by 20 minutes to almost two hours, depending on what the system is doing. Try it out!"

Not Just Laptops

[Bad to the Ben]

Why just the emphasis on laptops?

Wasted energy from a wall outlet is still wasted energy. Transferring the energy-saving mindset to the desktop would likely have some positive results, especially for all those people using a 3GHz machine to play Freecell and send a few emails.

Since when do desktop PCs feature throttle capable PCs, adjustable brigthness Flatpanels and other software adjustable power settings? (Besides putting the PC into the ever energy wasting "Sleep" mode.)
