DELL E1505 CPU

[dsonyay]

Hi-
I'm running PCLINUXOS 2010 on a Dell E1505 laptop (running PCLINUX only).  It's running a dual core T5300 @1.73Ghz (in PCC -> Hardware, 2 processors are shown)

Anyway, all I do is surf the web, check e-mail, watch some youtube videos, or movies on occasion.  NO GAMING.

Is there a way in PCC or KDE System Settings to run the CPUs at Powersave or at a slower speed so they run cooler and my fans don't run so much?

I'm not timid about typing in some commands in a terminal, so if I have to go that route, I don' mind.

Thanks!

try this, open a terminal, su to root, and type:

Code: [Select]

cpufreq-set -c 0 -g powersave
cpufreq-set -c 1 -g powersave

verify with:

Code: [Select]

cpufreq-info
if it will work, as expected, you can make this change permanent by editing the file /etc/sysconfig/cpufreq, changing GOVERNOR:

GOVERNOR=powersave

and rebooting.

Yes, awesome, I tried this and it works fine.

Weird thing is when I go into KDE -> Configure Your Desktop -> Hardware -> Power Management -> Power Profiles, the only setting I can choose is "Performance."   Also in the Global Settings - Performance is the only choice as well.   Why is that?

the other profiles have been "lost" along an upgrade some time ago ...  ... may be from 4.5 to 4.6 ... You can still add you own profiles ...

Yes, but if I add my own profile, there is no way to select a cpu freq--  like 800000, etc for Powersave. 


When I edit the cpufreq file, there are # symbols at the start of some lines... do I need to remove these in order to make those lines valid?

yes, the # at beginning of a line must be removed, additionally check in PCC (control center) -> system -> manage services: cpufreq service should be enabled.
