Toshiba Satellite U500 PSU5EA-00X012 laptop overheats with ubuntu 10.04 Lucid Lynx

Asked by Max

Toshiba laptop dual boot with Lucid 10.04, overheats quickly, fan runs intermittently but does not cool computer. Runs perfectly cool in Windows 7. Tried Thinkfan but didn't do anything.

Not technically oriented but can follow directions well. Many thanks for any suggestions, want to go Ubuntu all the way, but keeping Win7 sector as backup till I work out the details :)

What Win7 does or doesn't do is of no value. It is a totally different OS with different support.

What is the exact make and model of the device. Toshiba make a HUGE range of systems. Specifics are very useful.

Looks like a common issue. Its probably some garbage software cooling rather than a nice hardware solution.

All I can suggest is log a bug

I found this solution:

-----------
open up a terminal and enter "sudo gedit /etc/default/grub"
look for the line saying GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
after splash (within the quotation marks) add acpi.power_nocheck
Close gedit, save and execute sudo update-grub
------------

so far so good, have been running a couple hours, testing video, audio & etc and while not as cool as in windows it is definitely not overheating.

This was an easy solution to implement but I did not find it very easily.
