Description Pavel Kreuzt 2013-05-31 23:28:56 CEST 
The cpufreqd daemon fails to load and complains about being unable to get battery attributes on a laptop, resulting in poor power management. Without a plugged-in battery, it works correctly.

[root@Laptop etc]# cpufreqd -D

Version affected: cpufreqd-2.4.2-7.mga3

How reproducible: Every time a switch on the laptop with the battery the daemon doesn't start even it's enabled in systemd.

Comment 1 Sander Lepik 2013-06-01 10:17:24 CEST 
Remove the cpufreqd daemon and if you already don't have it, then install cpupower. Edit this file: /etc/sysconfig/cpupower and make sure that cpupower.service is enabled and started. Does it work this way?

Comment 2 Pavel Kreuzt 2013-06-01 18:54:28 CEST 
It worked for me, thanks. But I think there must be an issue with cpufreqd anyway. It's not the way it's suppossed to work, is it?
Comment 3 Sander Lepik 2013-06-01 19:23:26 CEST 
Well, it's quite possible that we'll drop it for Mageia 4. cpupower usually gets the job done and does it better.
Comment 4 Pavel Kreuzt 2013-06-01 19:41:17 CEST 
I didn't know about cpupower, but I like what I see. It's simpler and easy to configure and to change settings on the fly.
Comment 5 Marja Van Waes 2015-03-31 16:04:58 CEST
