ну в общем так.
нотбук вот такой http://www.knsneva.ru/vcd-327994-1-336509/goodsinfo.html?from=ya
борюсь за энергию. Проведены слудеющие орг-мероприятия
1. ядро 2.6.38-rc5
2. ядро стартует с параметрами quiet acpi_osi=linux usbcore autosuspend=1
3. драйвера на видео ATI Версия: 1:6.14.0-1
4. вот такие действия в профиле для батарейки
for i in /sys/bus/usb/devices/*/power/level
do
echo «auto» > $i
done
for i in /sys/bus/usb/devices/*/power/autosuspend
do
echo 1 > $i
done
echo 1 > /sys/module/usbcore/parameters/autosuspend
hdparm -B 1 -S 4 -M 128 /dev/sda
mount -o remount,noatime,commit=600 /
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
echo min_power > /sys/class/scsi_host/host1/link_power_management_policy
echo min_power > /sys/class/scsi_host/host2/link_power_management_policy echo min_power > /sys/class/scsi_host/host3/link_power_management_policy
echo min_power > /sys/class/scsi_host/host4/link_power_management_policy
echo min_power > /sys/class/scsi_host/host5/link_power_management_policy
/sbin/iwconfig wlan0 power period 2
/sbin/iwconfig wlan0 power 500m unicast
echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo powersave > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo 90 > /proc/sys/vm/dirty_ratio
echo 1 > /proc/sys/vm/dirty_background_ratio
echo 60000 > /proc/sys/vm/dirty_writeback_centisecs
echo 10 > /sys/module/snd_hda_intel/parameters/power_save
echo 7 > /sys/class/backlight/acpi_video0/brightness
результат конечно есть - около 2час30мин от батарейки если ничего не делать. что против 5 часов ничегонеделаья в винде слабовато.
