HOWTO: Fix Common ACPI Problems (DSDT, ECDT, etc.)

Hm, then I'm going to go ahead and guess that gkrellm isn't using that information at all.

On a more serious note, you should have some information there. Is that what it says while the battery is discharging?

Although my battery seems to be getting charged, etc, I'm still wondering if I made the correct changes to my DSDT. Although if this stuff all works except some small details, then I'm not sure what it could be.

A lot of people have reported issues with the battery info in 2.6.1 and 2.6.2. There is apparently a bug in the acpi code in those kernels, which could be affecting you. Do you have a 2.4 kernel (or 2.6.0) lying around that you could try, just to see if you get values to show up in those files?

Actually, this is 2.4.23 that I'm working with right now. I suppose I could try a 2.6.x kernel to test stuff out.

Here's another question that may be on the silly side. I was poking through the online package database and discovered that there were two packages acpi and acpid listed there. My impression from the various howto's were that with the kernel patched and modules included in it, there was no need for other programs, daemons or drivers to get the acpi to work. Especially since many of the elements in the /proc/acpi/ files are registering and working fine. Did I misunderstand? Are the extra packages something that I need as well?

Those apps won't do anything to restore missing information, but you may want to install at least acpid at some point to get your system to respond to acpi events. Basically, acpi just prints out some of the information from /proc/acpi. acpid watches for events, and allows you to put together scripts to respond to them. This is nice if you want to do things like shut the system down when the battery reaches a certain level, or put it to sleep when you close the lid.

You don't have to bother trying to hash out the dsdt file for me. They just posted a new patch for the 2.4.25 kernel which fixed the problem. The battery levels now register. Thanks for your help.

Sure, I'd be happy to share my stuff with you. To make it REALLY worth your time though, what kernel version will you be using? Personally I have had a lot of success with the 2.4.24 kernel. I have patched it with the latest ACPI stuff, bootsplash, software suspend, and of course a couple of the patches from this post.

Let me know what you need and I'll hook you up.

How can I patch kernels 2.6.x where x>1 ??
How can I patch 2.6.2, 2.6.3 kernels ?

I use 2.6.3 and I had no problems patching it with the newest ACPI patch, the DSDT Override patch, and the ECDT patch. I get the same ACPI support with 2.6.3 that I did when I patched my 2.4.24 kernel.

Have you tried these patches? If so, what did you have problems with?

I've got my patch

But the problem I have, also with mi DSDT fixes is that, I want to show it to you

Very nice guide!
I'm having the same errors as tkoster,
" Unknown reserved name ^ (_S0D)" upon 4 times... I don't have any idea how to fix them... Did you figure out what it means jetblack? I did a google but couldn't find anything usefull... Every ACPI aspect "works" but my cpu temprature is WAYY to hot (in linux over 50° even is idle, in windows idle around 33) so I tought it's the DSDT... I solved 1 error (except the 4 warnings) but still no go

Hello,

I have recently bought a new compuer, its a HP Pavilion a205w with a 2.7GHz celeron processor. Upon booting it up into Windows for the first time, the CPU fan was loud at first but then once at the login prompt it got quiet. I installed Gentoo the next day, and the CPU fan stays loud (It goes fast all the time instead of slowing down, and then speeding up when hot) I can run echo 3 > /proc/acpi/fan/FAN1/state and have it turn down, but then I can not get it back up again. I have discovered that it is most likely my DSDT. So I did what I found, and I get 1 error

I have a Toshiba 7140CT laptop, made in 1999. There were 30+ warnings, but all I had to do for every single one of them is change:

I have an asus A7N8X-X motherboard and ive recently been trying to get ACPI working. I tried disassembling the DSDT and found one error; i "fixed" it.

The problem remains the same. I wanted ACPI functionality in order to set processor states from C1 to C2 to bring the temperature down at idle times. This seems to work fine in windows, but not in linux. i have /proc/acpi/processor/CPU0/info, limit, power, and throttling, but info and power contain the following.

*bump*
Anyone knows how to solve my problem {see my reply above}?
Thanks!

Any idea on how to solve "Table [DSDT] replaced by host OS" problems? I've got it every time I've tried to fix DSDTs on various computers over the years. I'm assuming it means my DSDT was rejected by the laptop. Is that right?

And, confusion, I'm assuming you have a desktop chip, and as such is unlikely to support changing performance profiles.

dogshu · Posted: Fri Apr 09, 2004 7:21 pm Post subject:

"Table [DSDT] replaced by host OS" means that the host OS (Linux) replaced the system's DSDT. That is exactly what you want to happen, and is the entire point of this thread.

TinheadNed · Posted: Sat Apr 10, 2004 6:51 am Post subject:

Well that's good then. Unfortunately it means the new one doesn't make any difference on the old - and neither does changing the _OS variable.

There is definitely OS specific code in there, similar to what's been in this thread, but trying different string lengths made little difference

Hello, maybe someone is still watching this thread...
(I have posted it in its own thread, no answer so far, this is my second try):

I'd like to switch to 2.6.6; kernel from kernel.org, patched with swsusp2 and acpi-dsdt-initrd
:arrow:

My (self-corrected) DSDT is not loaded for reasons I do not understand... I even re-did the correction, with no luck.
It all runs well with 2.6.1! Odd, isn't it?

dmesg output:
