toshiba satellite amilo a100-998: cooling fan wont turn on

[terry_gardener]

laptop toshiba satellite amilo a100-998

Intel centrino duo 1.66.

the fan in the laptop is not turning on and cant even hear it, i have checked the log messages and that has confirmed it with a message saying:
acpi: transitioning device [fan0] to D0
ACPI: unable to turn cooling device [f7414468] 'on'

and this is repeated 5 times.

ubuntu intrepid (development branch) alpha 6
release: 8.10

The fan works in hardy and linux mint 5.

[mmomjian (matthew-momjian)]

can you install acpitool, then try running acpitool -f and seeing what it says? If it sees a fan, try running acpitool -F 1 to force the fan on.

[terry_gardener (terry-gardener)]

installed the acpitool and typed the above acpitool -f and got response fan : off.
i tried the next command acpitool -F 1 got message.

forcing the fan of/off is ony supported on toshiba laptops.
no toshiba acpi extensions were found .

the above is the exact textf given when running the commands.

This seems to be a kernel issue.

Can you report it at the upstream bug tracker at http://bugzilla.kernel.org ?

[terry_gardener (terry-gardener)]

bug report added to the above address under bug id: 11691

[Jouni Mettala (jouni-mettala)]

Probably kernel configuration change. 2.6.24-20 (hardy proposed) has these options. 2.6.27-4 hasn't.

CONFIG_ACPI_TOSHIBA=m
CONFIG_TOSHIBA=m

So probably no need to report upstream.

jouni

what file do i have to add these options to.

can i have instructions how to fix this.

[Jouni Mettala (jouni-mettala)]

Setting to confirmed. Let's wait suggestions from kernel team.

[terry_gardener (terry-gardener)]

they have suggested that i apply a patch to the latest kernel.

i have kernel 2.6.27.6-generic. from uname -r

please can you help with how to apply the patch.

i have never done this before and dont have a clue.

tried "patch -p0 < patch-name" and it says file to patch and i dont know the answer.

thanks

Ubuntu kernel team has released 2.6.27-10 kernel. It is available in intrepid-proposed. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Changes include: move toshiba laptops back from tlsup to toshiba_acpi. bug #269831

I am using 2.6.27-10 kernel, Ubuntu 8.10.
dmesg output:
.....
[ 2924.116311] ACPI: Unable to turn cooling device [f7418738] 'on'
[ 2930.116232] ACPI: Unable to turn cooling device [f7418738] 'on'

I have Shuttle KPC K4500 PC. My PC's BIOS offers 4 different settings for the CPU fan speed. Low, Medium, High and Auto. After experiencing weird resets of my PC, I changed the settings from Auto to Medium and now the PC is stable again. If you are wondering why I'm writing this report, it is because I noticed that this bug report importance is marked as undecided. Please excuse me for giving lectures, but I strongly believe that any bug that could possibly lead to hardware damage, in this case to the CPU because of a overheating, should be marked as critical. I triaged my problem, but there should be a mechanism for warning other users of Ubuntu for bugs of this type.

@terry_gardener -- there is an updares toshiba acpi module in the -proposed kernel which may well sort this out for you, testing there would be very helpful.

@Petar Velkovski -- Undecided simply means noone has triaged the bug and selected a level. Your symptoms sound similar, but as they relate to an ACPI issue on a different hardware platform you are very likely to need a different solution, therefore it is safest to file a separate bug for that, they can be trivially merged later if they are the same not so split.

patch mentioned in http://bugzilla.kernel.org/show_bug.cgi?id=11000 supposed to fix the problem, and is already in the Jaunty tree. Can you pls confirm that this fixes you issue ?

This bug report is being closed because we received no response to the previous inquiry for information. Please reopen if this is still an issue in the current Ubuntu release, Jaunty Jackalope 9.04 - http://www.ubuntu.com/getubuntu/download. To reopen the bug, click on the current status under the Status column and change the status back to "New". Thanks.

I'm having a similar problem with my Toshiba Satellite M115. The fan will turn on and off, however the computer occasionally overheats, due to the fan not cooling off the system (because it is off).

Running "acpitool -f" it will show the fan as being either on or off, but when I attempt to use "fan", "fnfxd", or anything similar to that, I get an error message similar to the following: "Could not open /proc/toshiba/keys" or "No Toshiba ACPI extensions were found".

This is with Jaunty, and has happened with both regular and 'proposed' kernels and packages.
