I recently installed Ubuntu 10.10 via WUBI on my Toshiba Satellite L505D-S9565, and I've had few issues except one: the laptop's fan does not run for any reason. I've talked back and forth with a few others and read some posts on similar issues.
Here's what I do know:
1.) I looked at /proc/acpi/thermal_zone/*/trip_points . The only option for * there is THZN. This is the output:
critical (S5): 105 C
passive (forced):<not set>
2.) Trying to get ideas from another post I ran pwmconfig. This was the result:
# pwmconfig revision 5770 (2009-09-16)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
3.) $ sensors returns:
Adapter: Virtual device
temp1: +39.0°C (crit = +105.0°C)
Adapter: PCI adapter
temp1: +47.5°C (high = +70.0°C)
As you can see there's not any data for my fan. (The temperature sensors seem to work fine, at least, which is a relief.)
However, /proc/acpi/fan/FAN1 is valid. There is one file in FAN1, state. sudo cat /proc/acpi/FAN1/state returned:
I think the problem may be that whatever bit of software that's in charge of cooling has no idea how to control my fan at all, even though it does recognize that the fan exists. I tried to carry out one of the posts regarding how to change trip-points but the package it mentioned does not seem to exist any more, so I'm pretty much stymied at this point.
This wouldn't be a major problem except that I have to have a large fan meant for cooling humans pointed at my laptop at all times. So currently it is a desktop that I can put into my lap if I don't mind being chilly. If I boot into Windows Vista, which currently only works in Safe Mode anyway , the fan does turn on, although it would be doing a lot better job of it if I could get the thrice-cursed thing to boot normally.
And despite the above infodump I'm really not sure what I'm doing beyond those few things, so if I ask a really dopey question...well, this IS the beginner forum.
Any help is appreciated.
