my notebooks HOT!!

ok.. i've noticed over the past week that my notebook runs really hot..
the cpu temp's are at abt 68 with lite usage like web surfing, and 65 while idling. the palm rest's are pretty warm but the bottom of the notebook's like an oven!!! the gpu temps fluctuate between 70 and 72 while idling and lite usage.

these are temps are a bit too high as, while running vista, i never get temp's this high when idling, or even even surfing..

is something wrong?? i'm pretty sure the fans are doing their job. are these temp's normal or should i be worried?

 

the GPU is ok...but the CPU temps seem high. I run about 55C on the Desktop CPU in this laptop......might wanna google that. I assume you've check your services to see what is running. Any indexing going on?

EDIT: I just noticed we have the same Video Card. CPU is high though, this one is a Desktop CPU and it doesn't get that hot. I get from 68 to 72 on my GPU....using Mandriva KDE

 

That's rather high. My CPU idles at about 40-45 C and hits 60 at load maximum (in rare cases, too). AND my notebook has a smaller form factor than yours. Did you just get this notebook? You might want to ask for a replacement if you did.

 

no, no idexing going on. but is there a way to check whether indexing is on? i've had this notebook for abt 6 months now. dont get these high cpu temp's in vista.

anythin else i can chk?

EDIT: ok i think it has something to do with power management. can anyone help me with cpu frequency scaling? i think the cpu's running high even when its idling.

 

I think it's a setting somewhere....you have CPU set to DYNAMIC right in power management?

 

is that in the bios?

 

No, go into a terminal and type

gksu gnome-power-manager

then look at the settings and make sure dynamic is selected. Also, look in services and make sure the cpu-freq module is loading I think....not in gnome now

 

ok i typed in the code but nothing's happening. also wen i add the cpu frquency scaling monitor applet to the panel it says that frequency scaling is not supported?!?!!?!

 

yeah, it's something with CPU scaling/power management....shouldn't be difficult to correct....someone using gnome needs to step in here........knock knock? I would say go to synaptic package manager and search the following: gnome-power-manager, and cpu-freq. See if they are installed, if so, I'd mark them to reinstall and reboot then go into gnome power manager....I just can't look at what you're looking at now. But that won't hurt anything for sure.

 

I just installed Ksensors, then rebooted....at first it showed my CPU at 67 degrees! but after a while it dropped down to 55C which is normal for this CPU. Have you given it time to adjust?

 

type this in terminal gconf-editor &

Then navigate to gnome-powermangement under apps. Then you will see the option to change the CPU frequncy. My laptop was running pretty hot under perfomance and now I have changed it to ondemand.

This is in Ubuntu.

 

@amidond:
i changed the cpufreq to ondemand.. but i still dont see a difference! notebook still running at same temp's.

now i getting really worried..

 

Try the Ubuntu forums, I only just installed over the weekend so I don't know very much about Linux just yet. I do notice that I can get almost 4 hours battery life in Vista and only a little over 2 in Ubuntu.

I have to do some more research yet. If I find anything I will post it back here.

 

Are you running any compiz effects? And is laptop-mode enabled?

 

ya am running compiz in custom-settings. also laptop-mode is enabled.

 

Wait.....don't think laptop-mode should be enabled as it's overridden by power manager I think...check services and see that laptop mode has a status of STOPPED, but checked to start at boot is normal. Sounds like a conflict.

EDIT: compiz will run it up a little itself, but not that much.

 

setting cpufreq to ondemand wont do jack unless its correctly reading how the frequency ranges your cpu can go up and down (aka proper module for laptop is loaded)

try these commands as root


modprobe acpi-cpufreq

then

cpufreq-info


read the output and check if the frequency scaling ranges are correct, typically it should be 1.20 --- your max cpu speed

if incorrect edit /etc/conf.d/cpufreq as root and try to manually specify the min and max speeds your cpu can go to (for latest core 2 duos min is 1.2GHz and max is your max speed)

in this file you can also set the governor, set it to ondemand.

to set frequency governers through terminal just type as root cpufreq-set -g governor name

 

I don't understand why he's having a problem in the first place Mint.....

 

cpufrequtils not even installed ?

botched install ?

bad iso burn ?

laptop hardware not properly detected and setup (daemons modules..) ?

 

ok here's wat i got after cpufreq-info...

the after entering /etc/conf.d/cpufreq as root, it says no file or directory found? wat am i doing wrong? i'm guessing i have to manually specify the min and max speed..
thanx for being patient so far guys..

 

I probably would do a another burn and clean install to /. and leave my /home as it is....

 

hmm..
u think thats my only option?

 

No, but it might be easiest if you have a separate /home....all your settings will be intact...you'll have to reinstall a few programs probably....something could be glitched, but a one of the more savvy users around here might be able to help you....but, I think that's what I would do since it's fairly easy.

 

Your setup is looking good. Ondemand governor is loaded, and the available frequencies are detected. But according to this line your governor is not using them all, and is running at full speed:

Do you have any cpu settings in your bios? Something like "Run at full speed when on a\c"? You could also try to unplug your laptop and while running from battery check which frequencies the governor is choosing from.

 

ok i fixed the issue... i had to edit the /etc/init.d/cpufrequtils file and manually enter the min and max cpu freq. thanx for the help guys!

looks like i wont have to reinstall mint!

 

Good for you....I'd take note of that for the future for that notebook

 

Nice to hear, you would have gotten their sooner if I had mentioned the correct path to that file in my previous post (mentioned the path used in Arch instead of Mint)
