laptop got hot, no fans! (acpi tools to check fans/temp/battery?)

[Mr. Adam ALLEN]

pre-severn the laptop (Dell Lattitude L400) would use apm- and I could
use the apm utility on the command line to check the battery status.

Does severn have any command line utilities to show the battery status,
(hopefully temperature) as well. I had a quick look at
http://grahame.angrygoats.net/acpi.shtml but that doesn't work straight
off with severn. The reason for wanting these tools....

A little concerned (rebuilding the 2.6 test2 kernel and the fan never
came on- this is running the severn default kernel). The machine decided
to power itself off after half an hour. 
I want to make sure that severns kernel isn't stopping the fan coming
on. Let the laptop cool down and tried rebuiliding the kernel again-
same thing, no fans after 20 minutes and the laptop getting hot enough
to burn. I've fallen back to appending acpi=off for now. 

I've kept the output of dmidecode and acpidmp if this would offer any
help in tracking down the problem.

the acpi project has some fixed DSDT tables for DELLs. I've read that the L400 
is similar to C, so you can try the C640. Otherwise, you can do what I did:
dump your table, decompile it and compare it with the C640 custom (i.e. look 
at the fan section and try to understand what;s happening there, or replace 
the section altogether..). Unfortunately I don't have a L400.. :(

All you need then is the patch for osl.c to load your own one (there is 
another patch to load the table from initrd so you won't have to compile the 
kernel every time..)

Hi,

afaik, Dell is known for bad DSDT's. A solution is to have a look at the acpi 
project on sourceforge for fixed DSDTs. They have a small howto on convincing 
the kernel to load your patched acpi image instead of the system one.

another thing would be to look in your /proc/acpi to check out if you have a 
subdir "battery". if not try the following:
modprobe battery
modprobe ac
modprobe processor (in fact, you should load all the modules in 
/lib/modules/2.6_blah/kernel/drivers/acpi :) as they are not loaded by the 
"acpid" in startup.

Then everything should work ok. I have an X200 and had loads of fun with this 
over the w/end :) (not).

Cheers,

Laur

IIRC, on the inspiron 8500, there isn't fan support in the DSDT.  But...
i8k works for fan management.

modprobe i8k --force=1

/proc/acpi was missing the battery,fan etc so I made a few modprobes and
started re-compiling the kernel again. Still no fans.

I'll stick with the noacpi for now, and investigate the acpi  project on
sourceforge.
