High temperature - Lenovo

sefsinalas · 2012-02-09 08:37:19

Hi. I have the problem with the temperature. The notebook gets too hot. I have read and tried everything in the web but the problem persist. The sad part is that the same notebook with windows has much less temperature.

Sometimes the notebook turn off by itself due a high temperature. Almost daily.

I'll put all the informacion of my pc and hopefully you can help me because i dont know what to do.

General
Lenovo G460
Video Intel HD Graphics
Intel(R) Core(TM) i3 CPU M 380 @ 2.53GHz
3Gb de RAM
Arquitectura x86_64
Kernel Linux 3.2.5-1-ARCH

sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +50.0°C (crit = +127.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +50.0°C (high = +80.0°C, crit = +90.0°C)
Core 2: +43.0°C (high = +80.0°C, crit = +90.0°C)

For some reason the sensors command only shows me these few data, I see nothing of the fan speed and other data. Normally the temperature is over 70. When i decompress a big zip or I have 3 flash videos open the temperature rises to over 80

Sorry, I don't have a solution, since it seems to me that you already tried possible way to reduce power usage. Furthermore, it appears that under normal usage the temperatures are ok, as you posted above.

It does seem, however, that your laptop has cooling problems by design when doing power hogging tasks. Have you tried running simultaneous intensive tasks (maybe more flash videos, or gaming) on windows and see if it shuts down also there? It might be that windows handles flash better than Linux and hence uses less power

@sefsinalas, you being modest?
The temperatures you are having are the absolute and sassiest norm - particularly for the type of operating systems Dell makes these machines!
I have a Studio XPS 16 (an i7 with Radeon) and it never goes down below 66 C even in idle mode with more than optimal settings like yours. I don't see much different cause Windows typically runs 5-8 degrees cooler.

And btw, Dell and ATI are notorious for cpu and temperature hogging. It seems to me that Dell makes laptops for people living in north pole (I guess all of my Dell laptops collectively generate 200 BTU of heat)

I'm not sure that Dell's failings are relevant here since the OP appears not to have a Dell laptop.

Have you followed the wiki instructions for setting up sensors correctly to get as much information as you can? I don't get much but I do get a bit more (including fan speed) after following the instructions:

acpitz-virtual-0
Adapter: Virtual device
temp1:        +47.0 C  (crit = +100.0 C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1:         567 RPM
temp1:        +47.0 C  
temp2:         +0.0 C  
temp3:        +47.0 C  
temp4:         +0.0 C  
temp5:         +0.0 C  
temp6:         +0.0 C  
temp7:        +24.0 C  
temp8:         +0.0 C  

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +46.0 C  (high = +86.0 C, crit = +100.0 C)
Core 0:         +45.0 C  (high = +86.0 C, crit = +100.0 C)
Core 1:         +46.0 C  (high = +86.0 C, crit = +100.0 C)

Have you tried any of the options for reducing power usage by the graphics card via options on the kernel command line? I'm currently passing these (which are mostly to do with graphics):

pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1

You should read up on these before using them, though, as they are not enabled by default because they can cause problems.

You don't need to load cpufreq_ondemand or cpufreq_powersave explicitly if you are using laptop-mode-tools. You also don't need the cpufreq daemon. I've got acpid loading but maybe this isn't necessary, I'm not sure. Maybe something else is starting it in your case?

I have the same problem or even worse (i'll tell u why) on a

Dell Inspiron Q15R 5110-8104
CPU: i5 2430M / 2.40 GHz
GPU (onboard) : Intel HD3000
GPU: NVIDIA GeForce GT 525M

The thing is that I have not yet installed arch linux on my system! Even when booting from the live CD , (no GUI no nothing just plain CLI) i get hot air out of my laptop and the fan works constantly.
I reboot on Windows and it instantly gets cooler and the fan works only when needed.

When booting from the live cd I get an error like:
*ERROR* MUX INFO call failed
and also something about nouveau drivers not able to load. (Invalid ROM contents)

So I am thinking is this related to the two graphics card problem? (https://bbs.archlinux.org/viewtopic.php?id=111855)

Any possible solution?
When I first bought this laptop and was testing arch still from the bood cd , the laptop turned off and never turned on again (probably the momo burnt) but luckily i had same day replacement as the laptop was brand new. If arch is related to this then this is a very serious problem that can ruin hardware. I'm no expert so sorry if some of the things I say sound .. noobish

If you are using the latest kernel with latest hardware, there's no need to use pcie_aspm=force.
Matthew Garrett's patch was found to be effective by early deployments by most of distributions. Its included since Linux 3.2.5 and it works for me on my Latitude and XPS.

@cfr, lately Dell's been hot. I have owned every major Dell laptop model that's been there since 2006. And I know it!
You can even bake an egg with it
