[toshiba Z830] [Quantal] Fans no longer working and cooling machine temperature always high

[Laura Czajkowski]

when I start up machine a bubble appears saying sensors are all 0 degrees after 5 mins of usage heat temperature shows 70 degrees few minutes later it rises to 86 this is where it sits most of the day.

Fans don't seem to be regulating the machine.

Doesn't matter if there is 1 application running or 10 Temperature is always high

@Laura -- we need to identify what if any kernel this worked for in 12.04. You should be able to download and install the latest 12.04 kernel and run it against your quantal userspace. You can find those kernels in the version page for the linux package:

    https://launchpad.net/ubuntu/+source/linux/+publishinghistory

If you could try the latest 3.2.x kernel and let us know if that works.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1063670

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[penalvch (penalvch)]

Laura Czajkowski, did this issue not occur in a release prior to Quantal?

As a potential WORKAROUND, if your CPU sensors approach overheat/auto-shutdown, you could governor your CPUs by executing the following via a terminal:
sudo cpufreq-selector --cpu=0 --governor=powersave && sudo cpufreq-selector --cpu=1 --governor=powersave && sudo cpufreq-selector --cpu=2 --governor=powersave && sudo cpufreq-selector --cpu=3 --governor=powersave && cpufreq-info

christopher I can't be sure I had the laptop only a few weeks on precise and it was new. Since upgrading to Q it's just been a nightmare with temperature always at 71 degrees and often sits at 86 most days.

I've tried different kernels and still the fans are not coming on early enough to stop it raising so high.

[Laura Czajkowski (czajkowski)]

I should add I've tried the following:

3.5.0-17
3.2.0-22
3.0.0-15

Fans do come on when it reaches 86 degrees but not for long and then goes back to sitting at 71

[penalvch (penalvch)]

Laura Czajkowski, using my own Toshiba Satellite L305D-S5934 as an example, at ~100 C the PC would turn off due to overheat. One would be entering problem territory >~93 C. Howver, while 86 C is bordering on higher than desired, I've had no problem running it around that in Quantal. I just had to be ready to implement the previously mentioned WORKAROUND.

Just to clarify:
+ Using the kernels 3.5.0-17 3.2.0-22 3.0.0-15 the fans came on around 86 C and would stop at 71 C?
+ When you say they fans stop at 71 C, is it that the fans spins lower/unaudible, or it comes to a complete stop?

[Laura Czajkowski (czajkowski)]

Christopher, when it is at 71 there is no fans running.

Yes I did look at the work around but I'd be more interested in finding a solution also. I will try it with a precise live cd in a week when back in the UK.thanks for the help though.

[Laura Czajkowski (czajkowski)]

with the help of Leann yesterday I installed the latest precise kernel, and now my temperature is at a constant 16 degrees :D

[penalvch (penalvch)]

Laura Czajkowski, great! Could you please share which kernel version specifically you installed?

[Laura Czajkowski (czajkowski)]

czajkowski@sheldon:~$ uname -a
Linux sheldon 3.5.0-18-generic #29-Ubuntu SMP Fri Oct 19 10:26:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

It's still having issues when plugged in and still around 72. I'm hoping to find someone at UDS to help further debug this.

[penalvch (penalvch)]

Laura Czajkowski, as per http://www.toshiba.co.uk/innovation/download_bios.jsp?service=UK an update is available for your BIOS (1.80). If you update to this, does it change anything?

If not, could you please provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

As well, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.10-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

upgraded to Raring so no longer have a quantal machine to test on
