Hello All
Equipment : Satellite L300 20D running Karmic64 Fan now operates correctly i.e. on at 55c off at 40c after doing the following :- sudo gedit /etc/default/grub and then change GRUB_CMLINE_LINUX_DEFAULT="quiet splash" to read ..."quiet splash aspi-osi=Linux" After which don't forget (I did!) to run sudo update-grub to update /boot/grub/grub.cfg Thanks for the thread. Saved my blood pressure. |
It is acpi_osi="Linux" and yes this workaround seems to work great on L300 model...but not on L505 ;)
|
Thanks for the correction.
You would not believe how often I misread text. The penalty of old age. Cheers. |
Eventually, I've found that it was PowerPlay and not ACPI that was causing this issue....PowerPlay is used by ATI card to reduce consumption of graphic cards....and with open source drivers, it's not implemented yet...so I've installed proprietary drivers and now, the fan is running at normal speed and the general temperature is even cooler...
Something positive : powerplay will be soon available with latest branch of open source drivers ;) |
I want to say how glad I am to have found this thread. I hope this thread continues so all the issues on this thread is solved. I would really love to see Toshiba providing some insight on this issue.
Hmm, I have Fan issue. From suspend to ram, when resuming, the Fan does not wake up and I have to assume is because the temperature is low after reading this thread and some research so far is the cause. When the Critical Trip point is passed, the Fan is turned on at high speed and never reduces speed. It's amazing how loud this fan could be, in a conference room, it annoys everyone!!! lol I had updated my Kernel 2.6.32 and BIOS 1.80 and appended apci_os="Linux" to my Kernel line and to avail, no effect but to see apci_osi="Linux" is possibly the correct one. I'm going to try that now =]] Here's some input: Code:
Kernel version : 2.6.32-41-deskt - ACPI version : 20090903 |
Hello.I am now using Satellite L526.
there is a patch for fn key here: http://patchwork.kernel.org/patch/75186/ The author says it's ok for Satellite A40. I tried it ,not work for L526. |

For anyone who cares: Toshiba Canada has posted an update BIOS for the Satellite 300D on their support site. It upgrades the BIOS from Insyde H20 1.70 to 1.90 ( what happened to 1.80??)
Having done the upgrade, my fan now acts appropriately and is following the speed of the processor i.e. at 1.9Ghz is on louder and at 8 Ghz the fan slows to an inaudible crawl. This fix tells me the nature of the problem : the bios. Hope this is of some help to someone.... |
I can confirm with ceyx that a BIOS upgrade to version 2.2 solved my Function Key and fan control problems for the Satellite L300 laptop. I have completely documented this at:
https://wiki.archlinux.org/index.php...Satellite_L300 |
lggagnon I have got my fan to auto kickin and turn off again but it lets the laptop run fairly hot still. what temperature does your fan kick-in? cant confirm the function keys work for me unfortunately
|
netsurf: kicks in at about 40C, spins faster as it should at 50 and again at about 60C. Did you update the BIOS as I suggested? Also, remember my article states kernel version 2.6.36. With Ubuntu 9.04 you might have an older kernel than that, which perhaps makes a difference.
PS: Have you checked "top" to see if perhaps you have a runaway process that is consuming 100% CPU? |
Laggagnon, forgot to mention I am using lucid on that laptop (10.04) its possible that maverick works better however there was no noticable difference when I checked previously with a live disk although its quite possible it could have been fixed. Your threshold for the fan kicking in appears to be alot lower than mine is however.
Start 55c stop 40c next fan stage at 60c fnkeys do not work at all in terms of brightness control for me but if memory serves the suspend key does. They all print a "~" in the terminal instead of functioning. I tend to be quick to capture CPU hogging tasks as I monitor my fan temperature and cpu usage just incase it gets that bit too hot |
hello all,after suspend/wakeup,the fan speed control and fnkey adjust brightness work perfectly here.i don't know why,hope somebody could solve it.i have contacted to others,and get the same result.l526 here.
|
netsurf: those temperature kickins seems still reasonable. If you listen very carefully at 40C you probably should hear the fan whirring very very quietly. You did not answer my question though - what BIOS version are you using??
As described in my Arch wiki article, the Fn key will work properly with recent BIOS's, but you might have to bind the key combinations to specific facilities to get all you function keys to work. For instance I had to bind my brightness keys to "xbacklight" to get those keys to work. |

I have updated my bios use the latest version form toshiba site. any suggestion? |
can the BIOS be updated from linux? or do I need to re-install windows, Cause my BIOS is not corroborating with linux nicely, and I it hasn't been able to boot up windows. thanx
|
i believe there is a way to perform the update by extracting the bios firmware using the archive manager (ignore the fact that it is an exe) and boot with some key combination with the bios file on a fat32 pendrive.
must warn you right now this is very dangerous and could kill your laptop outright. it is far safer to setup a windows dualboot. the mechanism i describe is what i understand to be an emergency recovery from a bad bios flash and might not be any good to perform updates |

I already have the latest BIOS for my L300D (according to the Toshiba Europe site) and have tried to stop the fan from running constantly in Ubuntu, all to no avail. Will this happen with all Linux distros?

Hello All
I have a Toshiba L300D-20D The fan does not run to spec in lucid or maverick. This is an extract from my notes (gotta write it down or I instantly forget)... At first reboot the fan is running at max speed. Further analysis indicates ... Fan will not run at start or boot until emergency temp is exceeded when fan then runs at max speed. Fan will run continuously at low speed if wait until temp exceeds 50C and then reboot before emergency temp is reached. No idea why this is, but the cure is (credit due someone else)... sudo gedit /etc/default/grub Amend line GRUB_CMLINE_LINUX_DEFAULT=”quiet splash” to read “quiet splash acpi_osi=Linux” Save Then DON'T FORGET !!!!!!! Run sudo update-grub which updates /boot/grub/grub.cfg. Reboot Now.....fan on at 55C off at 40C. |

Kernel:2.6.35-28-generic The earlier suggestion of putting my laptop into suspend seems to do the trick for some reason. A bit of a pain that you have to do that every time you boot up though but at least it means the Windows partition doesn't get as much use! |
lenovo g470 BIOS=InsydeH20 3.5
hi
I own a lenovo g470 BIOS=InsydeH20 3.5 and have some fan issues too ... I made some research and found fwts , can you test it and compare to results of : http://rzr.online.fr/q/lenovo |
