I think i have a problem (power management)
 
I'm running -current (or 14) on an asus 1005ha and after noticing lowered battery time I started to check stuff.. check this out.

Code:

root@netbook:/home/weput# cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009

Code:

root@netbook:/home/weput# uname -a
Linux netbook 3.2.29-smp #2 SMP Mon Sep 17 13:16:43 CDT 2012 i686 Intel(R) Atom(TM) CPU N270  @ 1.60GHz GenuineIntel GNU/Linux

I have no idea what happened... maybe the upgrade from 3.2.28 to 3.2.29 broke something.

System has laptop-mode-tools installed and is not able to be activated

Please advice

Have a look at line 823 in /etc/rc.d/rc.modules and set the CPUFREQ option to on. i had to do that on my desktop machine to activate frequency scaling.

I also don't see a reason why this is off by default.

kernel-P4N1C 10-05-2012 03:19 PM

is empty...

I have a rc.modules-3.2.29 instead... maybe that's the problem.


Code:

#
root@netbook:/home/weput# less /etc/rc.d/rc.modules-3.2.29
.
.
.
CPUFREQ=battery

I'll make a soft link or something and reboot to see what happens

kernel-P4N1C 10-05-2012 03:35 PM

ok

didn't work

kernel-P4N1C 10-08-2012 08:56 AM

ok guys

I did the windows thing (format and reinstall)... and now i have it working..
