Ubuntu 7.04 Feisty Fawn
Power Management
The chips in T23s have the ability to run at speeds slower than their maximum, in order to save power. To see your current speed level, activate the CPU Frequency Scaling Monitor Applet. Right click on the toolbar and select "add to panel". You can search for "Frequency" to find it.
You can also enable this applet to allow you manually change the speed and scaling policy. To do that, run this in a terminal: "sudo dpkg-reconfigure gnome-applets".
These instructions are also available illustrated with screenshots.
You may also need to add a couple of lines to "/etc/modules" to allow you to be able to change the processor speed and governor. The lines are:
acpi-cpufreq cpufreq_ondemand
These will now be loaded on at boot time. To activate them immediately:
sudo modprobe acpi-cpufreq sudo modprobe cpufreq_ondemand
Some technical details are explained on the SpeedStep page.
