~ # dmesg | grep eth
forcedeth.c: Reverse Engineered nForce ethernet driver. Version 0.59.
forcedeth: using HIGHDMA

1. Screen on full brightness all the time
   (Fix) Dim Screen with [fn]f7 key combination
   looking for automated screen dimmer on battery
2. hald was probing /dev/hda and writing 20 lines to the logs every two seconds.
   (Fix)
   • Edit 20-storage-methods.fdi
     
   • change (match key="storage.media_check_enabled" bool="true") to "false".
     
   • Disables Autoplay.
3. Processor ran at 2GHz all the time
   (Fix)
   • emerge sys-power/powermgmt-base
     
   • create /etc/acpi/actions/pmg_switch_runlevel.sh, /etc/acpi/events/pmg_ac_adapter, and /etc/acpi/events/pmg_battery per the Power Management Guide. - gpm very useful here!
     
   • emerge sys-power/acpid-1.0.4-r5
     
   • Add acpid to default and battery runlevels - ~ # rc-config add acpid default
     
   • start acpid - ~ # /etc/init.d/acpid restart
     
   • ~ # tail -f /var/log/messages, unplug AC power, watch for runlevel change.
     
   • Insert "/etc/acpi/actions/pmg_switch_runlevel.sh "battery/battery" to local.start
     
   • emerge sys-power/powernowd - ~ # echo 'POWERNOWD_OPTS="-u 100 -l 40 -n -v"' >> /etc/conf.d/powernowd
     
   • Add powernowd to default and battery runlevels - ~ # rc-config add powernowd default
     
   • (Optional)emerge sys-power/cpufrequtils to poll/set processor frequency from userspace.
     
4. Airplane music listening tip
   To further extend the battery life, copy the t00nz you want to queue into a tmpfs RAM disk. Memory uses much less power!
   
   • mkdir in a place you can write (i.e. ~ $ mkdir ~/t00nz)
   • ~ $ mount -t tmpfs none ~/t00nz (You do have root | may need fstab entry)
   • ~ $ cp (mp3 location)/* ~/t00nz/
   • fire up audacious, dump the current playlist, make a new one from ~/t00nz
   • Read a pdf or three, and have your own t00nz as you fly across the continent.
     Close the lid to turn off the backlight to extend the battery even more!
