Power Consumption with Ubuntu 9.04 on 2133

[RonnyRenner]

Hi all,

I got a used 2133 for cheap and installed Ubuntu 9.04. I'm quite happy with it and also the battery lasts almost 4 hours (as long as I'm doing nothing ;-) )
I wrote a small guide how I did the install here

What I noticed now is quite strange. When the mini is running on AC power, the fan is always on and /proc/acpi/thermal_zone..../temperature told me that the cpu was over 80°C hot although the netbook was doing nothing, just charging the battery.

Somehow it seems like something is using much power when the netbook is running on AC. Does anyone have an idea how to solve this?

An on this topic, how do you handle with power management? AFAIK there's no frequency scaling for the VIA cpu...

You can enable cpu scalling
Press alt + F2
type
gksu gedit /etc/modules

and add e_powersaver line
it will look like this

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
e_powersaver

Right now I run on 798 MHz and It's enough to run ubuntu and web browser smoothly, only scale to 1,6 for youtube videos.
