I am the happy owner of an
Asus EeePC 1005PX with very low-end hardware and a pretty big battery. I am looking for the most power-saving distribution of Linux, and/or kernel attached, because I can't go over 4h20 of battery-life, and I used to do more before (like 6 to 7 hours. "Before" was always better, you know it).
My specs :
- 10' - 1024x600 LED screen (maybe it's LCD, 'cause I had to change it, and ordered one from Czechia or something like that on Ebay)
- CPU Intel Atom N450
- Integrated graphics
- 2Gb DDR2 SDRAM (I can go back to 1Gb if it means more powersave)
- HDD 250Gb SATA 5400rpm
- Integrated : 2x USB2.0 | 1x SDcard | 1x VGA | 1x Webcam + Microphone
My typical use :
Only on battery :
- Class notes (nano would clearly be enough... although italics and bold are useful)
- Web search (+ Flash for youtube/streaming video)
Only on charge :
- Watching movies (with headphones)
- Listening to music (with headphones)
My choices :
I was thinking... maybe I could use two distributions :
one for travelling and class, which would be veeeery lightweight and energy-saving, something like minimal arch installation with xfce and only mousepad/midori installed.
another one "regular" for movies and stuff, like Ubuntu with LibreOffice, Firefox, Flashplugin, blablabla.
My questions :
1) Would the power-consuming really differ from one configuration to another ?
2) What would be, factually, the most power-efficient
desktop environment and
web-browser I should use ?
3) Among these packages, programs, ideas, which are good (for power-save, of course) :
pm-powersave, "powertop recommended settings", "2D environment", "32 bit architecture instead of 64 bit",
laptop-mode-tools, "High contrast mode", "downclock hardware", "
CONFIG_MATOM used in kernel)"
4) Bonus question : Can I achieve "Deep Power Down Technology (C6)" with my Netbook and/or tweak voltage, if my BIOS doesn't let me touch anything except global stuffs ?
