[Acer Aspire 5315] Overheating triggers shutdown

[Tony B]

Dear Ubuntu people,

I'm using Ubuntu 10.04, but I had the same problem with 9.10. Both of these systems were installed on a partition.
Previously, I used Ubuntu 9.04 without problem, but this was NOT installed on a partition.
My laptop came with Windows Vista pre-installed: I do NOT experience this problem when running Vista.

(1) After a few minutes from a "cold" start, my laptop overheats and automatically shuts down. The "Core Temperature Sensor" indicates that it shuts down at 100 deg C. Other temperature sensors do not report any abnormalities.
(2) If I re-boot IMMEDIATELY, the cooling fan starts and the Core temp quickly drops to approx 45 deg C, and I can run my laptop all day without any problems.
(3) If I fail to re-boot immediately, or if I restart my computer before the sensor indicates at least 95 deg C, the computer will again suddenly shut down within only a few minutes due to overheating.

My laptop is an Acer Aspire 5315, but I've seen lots of posts on various forums. Toshiba computers seem also prone to this problem when running Ubuntu - and I have noted that Acer computers use Toshiba fans.

Everything I've read follows the same trend:
(a) it seems that, when everything is cold or only warm, Ubuntu fails to instruct the fan to run, so it doesn't.
(b) if the computer is already hot when it's switched on, the fan works perfectly. Presumably the computer has a separate thermostat to control this, since we know that Ubuntu isn't switching it on.

I'm sure this has been reported millions of times before. It is a major problem, and certainly one which prevents people recommending Ubuntu to others.

Thanks & regards,
Tony

[madbiologist (me-again)]

At least one user with this particular laptop solved this problem with a BIOS update.

[Tony B (tonesbox)]

Thanks very much, madbiologist. I've been told about a BIOS update before,
but I've also been warned that it could totally stuff up my computer. In
this part of the world, the electricity supply is very iffy at the best of
times, which I understand would make me more vulnerable to a problem during
a BIOS upgrade.

I don't wish to gamble on this basis -- I can think of better things to
spend my old age pension on (like food).

But thanks again for the thought.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in linux.

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

[Leo Arias (elopio)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it without more information.

Please run the following command which will attach necessary information:

apport-collect 579665

Bear in mind that you may need to install the python-launchpadlib package from the universe repository with 'sudo apt-get install python-launchpadlib'. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report.

For your reference, the full description of procedures for kernel related bug reports is available at https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies. Thanks in advance!

Hello Leo

Thank you for your email. I'm not the most computer-literate person in the
world, but this is the output from my terminal.

I didn't really understand any of this, but I hope it helps.

Thanks again for the help,
Regards,

That's ok. Thanks a lot tonesbox. If you have doubts, don't be afraid to ask.

Now please type this on your terminal:
( cd /proc/acpi/thermal_zone && \
while :; do \
  line="`date`:`grep temperature */* | awk '{ printf(\" %03d\", $2) }'`"; \
  echo "$line"; \
  sleep 10; \
done ) | tee LOG

This will create a file called LOG with the temperatures of your machine over time. And please attach that LOG file.

For your reference, you can take a look at https://wiki.ubuntu.com/Kernel/Debugging/HighTemperatures

Thanks for reporting this bug and any supporting documentation.

Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

[Tony B (tonesbox)]

I've recently discovered that I can make my overheating laptop problem disappear. And this, in turn, solves the premature shut-down problem.

I noticed that, if I close the lid of my laptop, it goes into suspend-mode. And the fan starts up correctly when I open the lid and continue working, even if the laptop wasn't warm when I initially shut the lid.

So my new Start-Up routine is:
1. Boot up laptop and wait until the desktop is displayed.
2. Close laptop lid and wait approximately 10 seconds until the system goes into "suspend" mode (on my Acer, the light showing that the laptop is switched on changes from steady green to flashing red).
3. Open laptop lid, type password to come out of "suspend". And, hey presto, everything works ok with no overheating issues.

This certainly works for me, I hope this simple procedure is of some assistance to others.

Cheers,
Tony B

[Phil. V (philip.v)]

Still exists in 11.10, also apparently some users have reported a BIOS update resolves the problem, as mentioned in duplicate bug 900557.

[Tony B (tonesbox)]

Hello Phil. V

Thank you for taking the trouble to keep me up-to-date.
It seems this bug isn't going to get fixed.

I've also heard that a BIOS update might well solve the problem, but
everything I've read suggests that this is not for the faint-hearted. I
understand that fluctuations in electricity will affect the procedure and,
since our power supply here often cuts out without warning 2 or 3 times a
day, I'm certainly not going to risk it.

In the meantime, I'll continue to use my work-around, which is:

1. Boot up laptop and wait until the desktop is displayed.
2. Close laptop lid and wait approximately 10 seconds until the system goes
into "suspend" mode (on my Acer, the light showing that the laptop is
switched on changes from steady green to flashing red).
3. Open laptop lid, type password to come out of "suspend". And, hey
presto, everything works ok with no overheating issues.

Thanks again for your response,

No problem, I figured the master report for this bug needed an update since a couple users have reported the same issue recently. Hopefully this gets addressed eventually, as your workaround would suggest that a BIOS update may not entirely be necessary.

[Tony B (tonesbox)]

I don't hold out much hope that this problem will ever be solved. To be
honest, I'd almost forgotten about other users, thinking that it might be
just a "quirk" of my machine.

I'm now running LinuxMint 9, with the same overheating problems. And I've
had the same experience with LinuxMint Debian Edition (I dropped that o/s
because of update issues, but am contemplating trying it again as
apparently their updates now work ok).

It would be nice to find a cure, but, in the meantime, I hope my workaround
is of assistance to others.

Hi everyone :)

Problem solved! I simply updated the old Acer Aspire 5315 bios to V 1.45.
the fan is now working fine
I'd also like to thank everyone for all the valuable info... it really
helped a great deal

Hello Haengcho

I'm glad you managed to update your BIOS successfully. However, this is a
risky procedure and shouldn't be necessary.

In any event, although it solves your problem, you haven't actually cured
the bug - merely ensured that it no longer affects your computer.

Regards,
Tony

Tony B, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. As per https://wiki.ubuntu.com/Kernel/PowerManagementASPM a patch has been issued to address overheating. Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

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

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[Tony B (tonesbox)]

*Dear Christopher Penalver*
*
*
*I thank you for your email and must apologise for this slow reply: I have
recently been travelling and away from an internet connection.*
*
*
*The overheating issue has very recently disappeared as mysteriously as it
came. I'm now using the Kernel 3.2.0-2-486 - and it seems to have solved
my problem.*
*
*
*I hope this is of use to other Linux users.*
*
*
*Sincerely,*
*Tony Boulind*
*
*
*
*
*PS Is there some sort of SOLVED comment I need to annotate to anything?
*

Tony B, this bug report is being closed due to your last comment regarding this being fixed with an update. For future reference you can manage the status of your own bugs by clicking on the current status in the yellow line and then choosing a new status in the revealed drop down box. You can learn more about bug statuses at https://wiki.ubuntu.com/Bugs/Status. Thank you again for taking the time to report this bug and helping to make Ubuntu better. Please submit any future bugs you may find.

[Phil. V (philip.v)]

Glad the problem is fixed,Tony!

Chris - correct me if I'm wrong, but wouldn't 'fix released' be a more appropriate status here? We have a couple duplicate bugs subscribing to this report, and it'd be great if those users were notified that the problem was resolved with a kernel update.

Issue resolved as of kernel 3.2.0-2-486
