So I was browsing lesswatts.org and it appears that acer did not set some stuff.\n\nI did these:\n\necho 1 > /sys/devices/system/cpu/sched_mc_power_savings\necho 3000 > /proc/sys/vm/dirty_writeback_centisecs\necho 10 > /sys/module/snd_hda_intel/parameters/power_save\necho 5 > /proc/sys/vm/laptop_mode\n\nFrom the batter tray icon, it looks that a got about ~20 mins extra of battery life.\n\nI then started looking at the network stuff.\n\n"iwpriv ath0 powersave" can take 1 2 or 3. I currently have it set to 3, but I have no idea which number does what. It could have disabled power save. I didn't bother looking for the source to see if the developers put any useful comments in there.\n\nif you're using the ether jack, you can try setting this:\nethtool -s eth0 autoneg off speed 10\nSeeing as you're on battery, streaming audio would kill it, versus playing from the system.\n\nI'll be setting up a vmware image with FC8 for compiling the 26 kernel, as there are a crap load more features for portable devices, as well as for powersaving features.\n\nIn the end, almost three hours from this little "stick" of a battery is not bad.\nHowever, I plan on breaking all this kde/gnome stuff down. I know that acer kept it in/used it for the integration that it provides, but I want a minimal environment. So I'm going to change the init to not load a lot of this stuff. WindowMaker for a windowmanager (yes, there is fluxbox, but it's not as productive for me, and wm has always been fast and efficient), some webkit based browser, and some small app to provide a clickable interface to turn on and off any thing I need. We'll see...\n\nSo far tuning the current environment is keeping me satisfied.
