|
I did install gentoo linux on my laptop HP nc6220 and running gentoo-sources-2.6.14-r2.
When I am booting to windows with out AC pluged in then in idle CPU is running at 387MHz. If AC is pluged it's running at 798MHz in idle. When I am changing AC plug IN/OUT durring windows is running nothing changing with frequency. low frequency id depend on AC state when windows is booting.
When I am booting to gentoo I have always low frequency 798. What do you think, is it okay, or it's should take care of AC state?
see following data of HW

Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: centrino
CPUs which need to switch frequency at the same time: 0
hardware limits: 800 MHz - 1.73 GHz
available frequency steps: 1.73 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
available cpufreq governors: ondemand, powersave, userspace
current policy: frequency should be within 800 MHz and 1.73 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware). |

As you can see i have nearly the same cpu, it dosen't go further down than 800mhz. how you get 3xx in windows i don't know, its probably not correct. |
