Looks like I spoke too soon. I ran the "echo 14000... " when I was docked
and all was well, speed could be set to 1.4 even 2G. Now that I am on
battery or even power (not docked) I would only get the CPU to go to 800
Mhz.
If I run the command
echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
to set the speed to 600 Mhz and it does it. Then I do the same thing with
2G
echo 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
The fastest the CPU will go is 800Mhz. Why will it not go any faster when
it
is undocked. This is frustrating.
Thank you.
I think that you first need to check what is the contents of
scaling_min_freq and scaling_max_freq
and use these values to echo into scaling_set_speed .
The value in scaling_cur_freq then tells you what is the cpu running at.
(works in my Thinkpad with FC3).
