Toshiba Laptop U500 running hot

[reef2dive]

I have a Toshiba Laptop U500 on running 10.04. It runs really hot, with a CPU temp of 88 C according to gkrelm. (Vista runs much colder.)

I do not have any proprietary drivers like special graphics drivers running. When booting 09.10 from stick I have the same issue, so I do not think it is related 10.04 only.

I ran sensor setup which added a parameter to the sensor list. (Sorry I cannot add exactly the command, as I do not want to run the laptop when it is running this hot.)

Is there a possibility to control the fan, so I can switch it on permanently?
How do I get sufficient information to post a bug?

sudo pwmconfig : what's the result ?

you may need to install: toshset and toshutils

its a fan acpi issue, try either:

1)
gksudo gedit /etc/default/grub

then replace the line GRUB_CMDLINE_LINUX=""

with GRUB_CMDLINE_LINUX="acpi.power_nocheck=1"

save

exit

then launch sudo update-grub

switch OFF THEN switch ON the laptop

2)
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=\"Linux\""

Save then update-grub

Thank you.


The setting
GRUB_CMDLINE_LINUX="acpi.power_nocheck=1" works.
With this command the fan starts at around 65 Celsius

The other setting does not work.
The fan does not start prior to reaching 100 C which is the same behavior as with the setting. At that time the fan only runs for 2 seconds and switches off and the temperature is not controlled.

Hi All,

I have updated the grub file to slow down the fan on my Toshiba Satellite A70 but none of the commands seems to work.
Here is a copy of my grub (partial) file in Lucia.



# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
# GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=\"Linux\""
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi="Linux""
# GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX="acpi.power_nocheck=1"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console


For now I am using GRUB_CMDLINE_LINUX="acpi.power_nocheck=1" which seems to work slightly better than the other commands.

Is there anything else I need to do before overheating and damaging the laptop's CPU?

Thank You,

Honestly I do not know. I am using gkrellm, which you can get through the package manager to check the temperature on the CPUs. According to that the Toshiba U500 is running fine.

need to experiment and google around (you are not alone )

GRUB_CMDLINE_LINUX="acpi.power_nocheck=0 ?

Thanks guys,

I ended up installing Ubuntu 10.04 inside of a Window's directory in order to remedy the noisy fan issue as well as overheating the CPU. I know that is a temporary fix but for now my laptop is running better...
I'll update as we go forward with this.

An update on this one.
After an upgrade of software, I do not know what happened, the machine started to run hot again.
I installed the proprietary fglrx driver as I thought that it would be better. Then I found an BIOS upgrade for this Toshiba U500 10L at http://eu.computers.toshiba-europe.c....do?service=EU which had been released 17.06.2010 which I installed. (You have to have windows for the BIOS upgrade)
Still no difference.
After removing fglrx driver and going back to standard, temperature is normal.

I was having the same problem (m305d laptop running REALLY hot, 80 C)and installed the proprietary driver fglrx 3d graphics driver and it has dropped my temps about 10-15 C. I know you said you tried it, but perhaps uninstalling and reinstalling it would work too?
