I don't have a laptop, so I'm just going by the thread you linked to.
When I navigate to... /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies, I get this response: cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies: No such file or directory.
Also reported in that thread.
I get the same result as reported by Sling-Shot "cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies: No such file or directory" on my Toshiba Satellite A305d running PCLOS 2010 with all the most recent updates
What kernel version do you have installed? canajun solved his issue by installing a different kernel.
I installed the pae.bfs version and that cured it.
There is no "cpufreq" folder in that file! I tried to copy it off the KDE install (via flashstick) and paste it into e17, but it won't let me do it, something about permissions.
The file has to be copied by root user. However, I don't believe just copying the file will solve your issue.
