What is wrong with my cpufreq now?

Question

cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to [email protected], please.
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0 1
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 10.0 us.
  hardware limits: 800 MHz - 2.40 GHz
  available frequency steps: 2.40 GHz, 2.40 GHz, 1.60 GHz, 800 MHz
  available cpufreq governors: ondemand, performance
  current policy: frequency should be within 800 MHz and 960 MHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
I use laptop-mode-utils. It used to work right. Not sure what happened.
let me post the answers to the inevitable questions:

lsmod | grep cpu

acpi_cpufreq 5697 1

Answer 1

Since you're asking what it means:
That's the frequency range your processor is allowed to run at.  I'm not sure about laptop-mode-utils but you (since I see "ondemand" as a the current governor) you can manually set it, depending on what you considered to be "working right" before (e.g. higher frequency, lower, etc).  If laptop-mode-utils is controlling this, it might be using the "ondemand" governor to conserve power by setting it to a lower frequency if you're on battery instead of A/C, or something.
Anyway, to change it manually (you may want to review your laptop-mode-utils configuration files first, check the Arch Wiki or any manpage associated with it), you can issue:
cpufreq-set -c0 --min 800Mhz --max 2.40GHz
That will put the processor back in it's full range, but if it's being controlled by your daemon it should be fixed there first.  I think you have 2 processors so you can issue the same command again but with  -c1   to change the second processor to the same frequency (if it supports the same range, which it usually does).
Again, if laptop-mode-utils is controlling this, you may want to consult the config files and/or manpages/wiki first.  I don't have it installed, but the above command will change the frequency manually if you want.
