Re: Toshiba Laptop U500 running hot
Hi, thanks for the tip.
I do wonder, as the machine started to get hot after an upgrade through apt. I guess there is a lib file out there that makes it hot. I am using ACPI off, which means, in my understanding that linux is not involved in the temperature control, the BIOS manages it by itself. So I do not understand, how an upper layer SW can block the BIOS from managing.
I am not using my laptop for that advanced graphics, just Compiz and cube, and I have not noticed any benefit with fglrx driver.
Re: Toshiba Laptop U500 running hot
The following commands fixed this issue for me on a Toshiba Satellite U500:
Code:
$ sudo -i
# echo 0 > /proc/acpi/thermal_zone/TM0/cooling_mode
This command sets the cooling mode of the device onto active cooling.
Code:
# echo 0 > /proc/acpi/fan/FAN0/state
Adding these echo statements before the exit 0 in /etc/rc.local made the change permanent.

Re: Toshiba Laptop U500 running hot
Thank you for the tip.
Just a clarification, do you use ACPI off in grub or not, when you use these commands?

I did not make any changes to the ACPI settings in the kernel line.
Re: Toshiba Laptop U500 running hot
In the setup there is this directory
Code:
# /proc/acpi/thermal_zone/TZ0$
is there any difference between TZ0 and TM0?
When issuing cat
Code:
# /proc/acpi/thermal_zone/TZ0$ cat cooling_mode
0 - Active; 1 - Passive
I assume that this means it is not activiated as acpi=off is used in grub
When issuing cat
Code:
# /proc/acpi/fan/FAN0$ cat state
status: on
What does the 0 represent in
Code:
# echo 0 > /proc/acpi/fan/FAN0/state
, on or off?
Re: Toshiba Laptop U500 running hot
That worked for me! Thanks so much.
Re: Toshiba Laptop U500 running hot
This worked for me, running Toshiba Satellite A305

Re: Toshiba Laptop U500 running hot
Hi
i tried to fix the DSDT on the toshiba U500
there was mistakes in fanX status methods so they always return ON
here are the dsdt files, if somebody can try on ubuntu ( i did on debian (i had to recompile kernel) )
now fan's levels turn on and off according to their trip points and i can monitor this with yacpi tool
hope it will help
edit: files here u500-dsdt.zip
Re: Toshiba Laptop U500 running hot
Thank you. I will try to use them.
(I need to check how to use them first.)
Probably I will have a result in 2 weeks.
Re: Toshiba Laptop U500 running hot
Okay, I am running a brand new Toshiba Satellite Pro L510 and this what worked for me. At boot, edit the kernel line to read:
NOT:
If it works, make it permanent in /etc/default/grub.
If you are still having heating issues, check this page:

I really wouldn't bother screwing around with anything else; you may just make a mess you need to fix on top of what you have. This is ALL to do with your 'acpi=?' setting one would think. Checking thermal monitors ain't gonna fix anything but will only confirm what you already know: The machine is running too hot.
