I looked all through here and did not find any posts for this so I am asking a question: How to get speedstep to work in an old T-23 so the CPU will slow down to save the battery when not plugged in? It runs full power all the time and shortens battery life. Power management to allow dynamic speed changes for the cpu has worked in the past with earlier versions of Suse and Mandriva…
IBM T-23 1.2 GHz Pentium III

I have cpufrequtils and powerd installed as well as microcode for obsolete cpu from laptop packages. What am I doing wrong?
