cpuspeed: 2g running at 800m

[Jamie Bohr]

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.
