Toshiba Laptop U500 running hot

[Ultim8linux]

The following commands fixed this issue for me on a Toshiba Satellite U500:

$ sudo -i
# echo 0 > /proc/acpi/thermal_zone/TM0/cooling_mode

This command sets the cooling mode of the device onto active cooling.

# echo 0 > /proc/acpi/fan/FAN0/state

Adding these echo statements before the exit 0 in /etc/rc.local made the change permanent.

I have added this to https://bugs.launchpad.net/bugs/572528

The first 2 commends resulted in this : -bash: /proc/acpi/thermal_zone/TM0/cooling_mode: No such file or directory

It dint work for me n my U500 is still OVERHEATING

you should try my DSDT, it works perfectly on my u500, fans behave like they have to, I can now compile kernels and stay at 70° C max

i tried the dsdt on dragonfly BSD too and it works.

the procedure to install custom DSDT depends on ubuntu version
or you can recompile your kernel

Or you can add:

acpi=copy_dsdt

... to /etc/default/grub.

Edit the kernel line at boot to see if it makes any difference and if so make the change permanent in the /etc/default/grub file.

Hi,

I am facing the same issue with a toshiba u500-12d: the fan will only turn on for a few seconds when the cpu gets near 100 degrees. I have tried the following:

• acpi.power_nocheck=1 - some improvement: fans work at lower temperatures and the cpu temperature stays below 75 degrees (but only after having put the laptop on standby)
• GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=\"Linux\"" - no change
• echo 0 > /proc/acpi ... - no change

Do you have any suggestions?

[vanoven]

Try :

acpi=copy_dsdt

as said Bucky Ball,
if that doesn't work ( it doesn't work on u500-11D )
you can try to use a custom DSDT, bios file for U500-12D seems the same as U500-11D one so it should works.

Perhaps we won't do all this stuff with the grub.cfg or menu.lst , all we have to do is to install TOSHUTILS and FNFXD from synaptic, it can't be more easy?

[reef2dive]

According to Synaptic TOSHUTILS only work with APM. In my understanding U500 uses ACPI.

[vanoven]

state method of power source for each fans is bogus

PowerResource (PF0, 0x00, 0x0000)
        {
            Method (_STA, 0, NotSerialized)
            {
                If (LOr (FSTA, 0x01))
                {
                    Return (One)
                }
                Else
                {
                    Return (Zero)
                }
            }

The method _STA always return "One" ( LOr (FSTA, 0x01) is always true )

OS (linux, bsd , other?) checks fan state before turning it on or off.
So Linux is always trying to turn off fans.

To get the right fans' behaviour you have to change the _STA method.

if you can't load a custom DSDT at boot i can try to integrate it to your kernel if you want.

here the kernel 2.6.35-23 #41 for ubuntu 10.10

dpkg -i linux-image-2.6.35-23-u500_2.6.35-23.41_i386.deb

Hi vanoven!
I'm having the same issue with my U500 "Ducati" edition. I tryed everything suggested in this and other pages, without solving the problem.
Finally I decided to install "your" patched kernel with the specific DSDT you provided, but I couldn't install it because I have a 64-bit system...
Is it possibile for you to provide a version compiled for 64-bit? or can you write a little "howto" or provide useful links to compile it by myself?
Thanks!!!

OK... finally I recompiled the Kernel, using this guide:
https://help.ubuntu.com/community/Ke...AltBuildMethod
To integrate a new DSDT I used vanoven ones, and this guide suggested in a txt file in the kernel source itself:
http://www.lesswatts.org/projects/ac...ridingDSDT.php
Finally I produced the 64-bit kernel and now the temperature is at about 50° and the fan is active... I expected a lower temperature, but now it works!
