[jaunty]XPS 1330 very hot

[Javier Jardón]

Kubuntu 9.04 and Ubuntu 9.04 alpha6

Since jaunty my laptop is very hot.
 - 40º CPU
 - 45º Disk

The fan is always running. This is not happening in intrepid

My laptop is a Dell XPS 1330 with intel graphic card

[Michael Rooney (mrooney)]

Hmm, my XPS 1330 does seem to be running hotter with Jaunty, although I have an nvidia card. Interesting!

[Andre van Rijn (avanrijn)]

Also on my Dell Inspiron 1720 with nVidia card, the fan is always running. Not happening in Intrepid or W*ndows. I have tried the Powernowd, but it makes no difference. Running Jaunty beta with the latest updates.

[Allen (allen-lau)]

Notice the same thing on my Lenovo x61t. Looks like there is this Kernel IPI thing that could be causing the issue.
First line from running powertop. Running Jaunty beta with latest updates.

63.6% (454.8) <kernel IPI> : Rescheduling interrupts

Notice the same thing on my Acer Aspire 2920 with Jaunty:

Disk:
christian@Jandraligeli:~$ sudo hddtemp /dev/sda
/dev/sda: WDC WD3200BEVT-22ZCT0: 54°C

CPUs:
christian@Jandraligeli:~$ acpi -t
     Battery 0: Charging, 92%, 00:12:33 until charged
     Thermal 0: ok, 46.0 degrees C
     Thermal 1: ok, 48.0 degrees C

And the fan runs nearly permanent.

After upgrade from intrepid to jaunty, my dell latitude D630 with nvidia card has a noisy fan permanently on. Not sure whether it is the CPU or graphic card fan.
Fan was usually quite with Intrepid and MS windows.

[Shootist (shootist2k2)]

Same thing:
laptop:~$ sudo hddtemp /dev/sda
/dev/sda: SAMSUNG HM251JI: 44°C
laptop:~$ acpi -t
     Battery 0: Full, 97%
     Thermal 0: ok, 43.5 degrees C
laptop:~$

Used to be lower (at the same termal conditions room is about 20 °C) with 8.04. I have T8100 with an NVIDIA 8400GS. Windows XP is around 6-8 °C better.

[Pascal Vandeputte (pascal-vdp)]

Same issue here. Could it be that this is xorg- or ati-related? Installing fglrx using "hardware drivers" makes my laptop crash, and the fan is continuously blowing hot air. Powertop doesn't reveal anything out of the ordinary, the CPU is running idle 99.8% of the time.

The default radeon driver as well as fglrx worked fine with Ubuntu 8.10 on this system, without running hot at all.

[Pascal Vandeputte (pascal-vdp)]

By the way, exactly the same thing happens when I try to load Mandriva Spring 2009.1 instead.

[Razvan Gavril (rgavril)]

Same issue here:

root@xps1330:~# acpi -t
     Battery 0: Full, 100%
     Thermal 0: ok, 51.5 degrees C

[mwendell (mark-wendell)]

Ditto for my HP 'Entertainment PC' laptop - ran cool under intrepid, but under jaunty, the fan runs hard all the time. The first thing I notice on booting, without running any extra apps, is that the default cpu load (according to 'top') is over 2.5!!! Yet top reports that the process with the highest load is XOrg, with only about 25-30% cpu usage. Very strange. I may need to roll back to intrepid unless this can be fixed soon... don't want to burn out my machine.

-Mark

[Michael Helfer (mhelfer)]

I can confirm this too. My fan on my xps 1330 is always running. This was not a problem with any of the previous releases. I have done both an upgrade install and a fresh install of the OS.

michael@xps1330:~$ acpi -t
     Battery 0: Charging, 35%, 01:42:14 until charged
     Thermal 0: ok, 56.5 degrees C

[Luis F. Lopez (luis.lopez)]

I can confirm that this issue is present in Lucid Alpa 2.

$ acpi -t
Thermal 0: ok, 57.5 degrees C

[Luis F. Lopez (luis.lopez)]

Maybe is a side effect of this bug?

christian imhorst , i have the same model hard disk and i have the same heating problem when on AC , kindly check this bug #399978 and confirm if you have the same problem with your hard disk

[Luca Gibelli (lgibelli)]

Same problem here, Dell XPS 1330 with geforce video card.

[Luca Gibelli (lgibelli)]

upgrading to 2.6.34 mitigated the problem, After using the PC for 1h I got 47°C. Before the upgrade/reboot the PC was running at 55°C.

[Mark (mark-f-bennett)]

@Luca: How does one go about upgrading the kernel? Is this something that would have to be released in a software update?

[mexlinux (mcanedo)]

I have upgraded to Maverick with kernel
2.6.35-20-generic

Same problem.

o@xps-mac:~$ acpi -t
Thermal 0: ok, 71.5 degrees C

[Palmar Thorsteinsson (palmar)]

After upgrading from Ubuntu 10.04 to 10.10 on my m1330 the nVidia 8400 GPU temperature rised from about 60°C to 70°C+ on idle. CPU temperatures seem a bit lower though.

It also seems to be cooler running Windows 7.

[Palmar Thorsteinsson (palmar)]

Found a *solution* to my problem: After reading this thread https://bugs.launchpad.net/dell/+bug/243637 I downgraded my nVidia driver from nvidia-current (260.19.06-0ubuntu1) to nvidia-173 (173.14.28-0ubuntu1). The upgrade to Ubuntu 10.10 Maverick must have replaced my graphics driver. GPU heat dropped back to ~61°C on idle.
Still around 10° hotter than I find comfortable, this is as low as I have been able to go.

Javier Jardón, thank you for reporting this bug to Ubuntu. Jaunty reached EOL on October 23, 2010.
