Please help: ACPI not working on DELL Inspiron 1150

[Ruslán Ledesma Garza]

Can anyone give me a hint on how to fix this? Anything would be useful. Am I 
in the right place for reporting ACPI bugs?

When doing "lsmod", response is "video                  16260  0", so I
think answer is yes.

No other events rather than ac_adapter are reported, including button
events.

Last time I checked (about 3 weeks ago) the bios firmware was the latest
("A07"). By the way, are DSDT's firmwares then?

I've already tried to build my DSDT using Intel's compiler. It showed
several errors (can't remember which ones, but I can do it again if this can
help). I think I fixed them, but could never get to install the modified
DSDT.

What can I do?

Re: Please help: ACPI not working on DELL Inspiron 1150

[Ruslán Ledesma Garza]

There is no mailloop. I thought the mail hadn't reached the mailing list 
because no one had answered me anything.

I thought I could get some little help but it seems as if I'm not in the 
right place or no one seems interested in making ACPI work on some Dell 
laptops. From what I've researched, I've discovered this is not an isolated 
malfunction.

What I ask is some feedback. What should I do first in order to get this 
thing fixed?

Besides I've been asking a few questions which I feel have not been answered 
very well.
-Is the DSDT a firmware?
-If it is so where does it reside?
-I found a tutorial on how to "fix" the DSDT. They talked about loading the 
DSDT on startup through an image file. What does this mean?

If you think these questions should not be asked here or that their answers 
represent a waste of time, please please let me know.

My only aim is to make this work and help my fellow users of linux on a Dell 
laptop have a better linux experience.

This is a maillist, pleas do not expect, that you get an answer within
hours... I would say if you didn't get an answer within 2 days it's ok,
to ask again... But if you ask again, please do not just resend your old
email. Think about why nobody answered...

Sort of (for more information go to www.acpi.info)

In the bios

The DSDT can be be replaced by the host OS a patch for this purpose can
be found at :
http://gaugusch.at/kernel.shtml.
In general it is not the right way to replace the DSDT. Linux should
work on any box without replacing the DSDT...
