same thing with satellite u500...fan starts only at 98°C for a few moments in order to lower the temperature to 96°C...which is the trip point I see in /proc/acpi/thermal/TZ0/trip_points.
I have tried to set the trip point with the usual echo -n "a:b:c:d" > /proc/acpi/thermal/TZ0/trip_points , but I get I/O error... Any Ideas???

I have a similar problem with ACER 5715. The fan never starts when I first boot up my system (it can eventually shut down when the temp. reaches about 90 deg. C). If I reboot when it's hot, then the fan starts at the boot and never stops (which is better than never starting).

No problems in Windows, and no problems before upgrading from Jaunty.

What information should I send? I don't have a clue on where to start looking for the problem.

Thanks in advance.

I have a toshiba satellite U505 laptap, after boot with ubuntu 10.04 Beta1 and when i start laptap the fan doesn't work in anytime, laptap continues heating up more and more and fan never starts.
please fix this problem.
That's why I could not use ubuntu 9.10...please fix this problem at the 10.04 LTS

I have a Toshiba L305D-sp6981A, installed ubuntu 9.10, started having heating issues, the fan runs at low speed
all the time, no trip-points defined @ thermal zone in acpi just critical @ 105Cº, fixed the errors in Dsdt table (decompliled
and complied again correcting bugs) to no use, configured acpi_osi="Linux" in /etc/grub (then runned upgrade-grub) and still works the same, fan not picking up speed, computer overheating... I don't want my laptop turned into a pile of melted plastic and silice but I love ubuntu and I'd never had this issues in windows (vista and then 7) I hope this issue is fixed on the finished version
so I can continue to impress the chicks with my cool SO.
Best regards!

oh, I've also tried my luck with the omnibook module, and It doesnt work either...

This is still a problem in 10.04 on my Toshiba L305D-S5959. Setting various boot parameters as mentioned in previous posts (and even some not mentioned) so far have had no effect. The fan is either off and stays off until the critical point is reached and the system shut itself off, or, if the laptop already toasty (70°C or higher), the fan runs full speed even if it cools down to around 45°C or so. No trip points are set except for the critical of 105°C, which is way too hot IMO.

Both 9.04 and 9.10 ran just fine in this regard. This is a dual boot laptop, and the only thing that happened between the upgrade to 9.10 and the beginning of Beta testing for 10.04 was Windows 7 was installed on another partition. Vista and Windows 7 had/has no heat issues either. This laptop was purchased in August 2009 when a promotion was being run for the free Windows 7 upgrade.

I'm beginning to suspect something was left out of the kernel or was replaced that was in the previous versions' kernels. Running a 32-bit or 64-bit ubuntu build makes no difference either. Because other issues kept nagging for attention during beta testing, I never quite go around to reporting this previously.

One thing I have noticed that I thought was odd is the the file /etc/default/acpid is entirely commented, so no acpi modules are being loaded. Enabling loading of ACPI modules makes no difference though either.

My next experiment is to see if I can re-load 9.10 or Debian Lenny to see if the heat issue continues or not.
