Since I upgraded to Lucid, I didn't see this problem any more. I am not
sure what fixed it but my laptop fan is working great in Lucid.
right now I am at kernel version 2.6.32-24-generic and I didn't see this
problem any more.

This shows the problem well. What I found though is that i8k alone does
not control the fan. It only offers an interface to it. It is i8kutils
that allows to do that. Otherwise it seems to me the BIOS is in charge
of controlling the fan. Testing the here with an 1535 it looks like it
normally
Please find the details below.

Description:Ubuntu 9.04
Release:
I have an inspiron 1525 with Kubuntu Jaunty 64 bit. the i8k module loads up
fine but it doesn't work, the fan doesn't turn off until it is almost near the
trip point and the the system shut down.
With Vista on this same laptop, the fan kicks off fine and the system stays
cool.
I started
You mean the fan does not turn _on_ until the trip point is nearly
reached, right? Can you sample the output of /proc/i8k while doing some
load? Like run the following in one terminal
while true; do cat /proc/i8k; sleep 2; done | tee i8k.log
and then run this in another terminal:
while true; do
Can someone confirm this issue on the latest Jaunty beta. If modprobe
i8k force=1 works and makes the fan working, there should be some info
in dmesg from the module about the vendor and model ignored. Could
someone post this? Thanks

As I understand it, the issue is that the module isn't loaded because it
believes it can't handle this hardware but it can; this means that
tables of supported devices need to be updated in the kernel, hence I'm
reassigning to the linux package as this is not an acpid issue.
Please confirm
Hi,
Found this tread in the forums, after searching thru lots of them. Look in the
bottom section and you find a solution with
sudo modprobe i8k force=1

That one did work on the Dell XPSM1710.
Not sure why i8k did not load without the
Hi,
I have now swapped my inspiron 9300 for a xps M1710
And guess what.. Still fan problem.
Insmod does not work, and fails with a -1 No such device error.
On the XPS I guess the temperature is what crashes my screen (with nvidia go
7950GTX), leaving it white and flickering (This happens
FROM: https://wiki.ubuntu.com/InstallingUbuntuOnADellVostro1700
For CPU, Fan and Temp monitoring
sudo echo i8k /etc/modules
sudo echo options i8k force=1 /etc/modprobe.d/i8k.modprobe
The options i8k force=1 is needed because the Vostro is not in the i8k
module list for supported systems.
