Eeepc 1000 HE power management

Hello,

I've succesfully installed Arch on my 1000he. Everything works fine! Except the difference in batterylife linux vs windows is horrible. It seems that this is because the asus utility on windows sets the fsb speed to a lower level. On arch I have yet to find such utility. I installed acpi-eeepc-generic, there is no support for this in there. Also when installing eee-control, wich is supposed to have this function, the performancetab is greyed out.

But it's docs say:

Known Issues

    * Under some circumstances, I2C/SMBus is not available because the BIOS "hides" the controller. In this case "i2c-dev" performance control cannot be used.

So I guess this is not possible with the 1000he.

Has anybody come up with a solution for this?

An interesting utility can be found;

It seems that this has all the needed functions. However there are only deb packages available. Has anybody tried compiling this on arch? (I'm a newbie when it comes to compiling

Thx in advance!

Hi,

I've had success scaling the cpu speed with cpufrequtils. Using the on demand module, my Asus 1000he runs at 1 Mhz most of the time but jumps up to 1.67 Mhz when necessary. This results in great improvements in battery life.

You should find all the necessary instructions at both these wiki pages:

http://wiki.archlinux.org/index.php/Asu … ufrequtils

http://wiki.archlinux.org/index.php/Cpufrequtils

Hope this helps.

Hi,
... my Asus 1000he runs at 1 Mhz most of the time ...

Wow, that's really low

Anyway, I also noticed that turning off bluetooth helps a bit and reducing the screen brightness also gives a huge boost in battery life.
I will take a look at the fsb thing when I have some time and see how it's done.

Ooops....

Contrary to appearances, I do proofread my posts, but those types of typos always seem to slip in. I meant to write 1 Ghz and 1.67 Ghz. Sorry about that!

Using acpi-eeepc-generic with the cpufrequtils support I am able to get the same battery performance.  Make sure to turn off bluetooth and camera when not using and most importantly, wifi.  If you do not need wifi, turn it off and it will increase your battery life by almost 2 hours.

So low screen brightness, no wifi, bluetooth, or camera and I am getting 9.5 hours battery just like in windows.
