A simple trick to conserve laptop battery power
Authored by: mono toto on Dec 08, '05 07:49:04AM

I used to do this but once I thought about it I couldn't understand how it prolongs battery life. The screen is lit by a fluro-tube and inverting the colour scheme doesn't lessen the fluro drain on power. Well I don't understand how lighting a black pixel is going to take less power than lighting a white pixel.

On the contrary, inverting the colour scheme works the processor/GPU a little harder (just try watching a movie on a low end system with the colours flipped). Though I guess your results speak for them self - perhaps I'm wrong.

To get the best run out of a battery I set the brightness to as dim as possible, run as few apps as possible (saves CPU cycles and writing/reading to/from the swap file) and turn off the airport & bluetooth.
