Dear Dom,
I have a Thinkpad R32 and the same problem (could not use EDCT). I hope that
IBM will release a new BIOS since ACPI does not work perfectly in Windows
2000 and XP as well.
(Meanwhile I am using APM instead.)
When I load the ospm modules (battery, etc.) there is no subdirectory acpi
under /proc but "battery" occurs directly under /proc and is empty.

Bye,
Jörg

Dear Sandro,

I posted the following message to the "Thinkpad A20,A21,A22,A30,A31" forum
at
IBM. Currently it looks like the posting has not been opened to public yet?
I
hope that IBM will provide a patch or that we can assist in creating a work
around for the buggy bios. I know several friends who are running Linux on
their A31's. Currently we all stick to kernel 2.4.19 + acpi-20020918 patch.
This combination provides at least some support for ACPI.

Thanks to the hard-working acpi-development team!
Dom

Hi all!

I am successfully running Gentoo Linux
(http://www.gentoo.org) on my new A31. Unfortunately
ACPI is not getting initialized properly with the new
acpi-patch from 20021212 ( + vanilla 2.4.20). I consulted
the acpi developers (http://acpi.sf.net) who told me that the
problem is the buggy BIOS! Is IBM aware of that problem
and are there any ongoing efforts to solve this problem?

Thanks!
Dom

IBM Thinkpad A31 | ACPI problems

[Dom]

Hi!

I have got a IBM Thinkpad A31 notebook (BIOS Version 1.04, 
http://www.pc.ibm.com/support?lang=en_US&doctype=&subtype=All&page=brand&up=unknownuser1004106089&menu=model&brand=IBM+ThinkPad&family=IBM+ThinkPad%7CThinkPad+A31&machineType=IBM+ThinkPad%7CThinkPad+A31%7C2652&model=IBM+ThinkPad%7CThinkPad+A31%7C2652%7CM5G) 
which is running Gentoo Linux 1.4_rc1. The previous gentoo-kernel based on 
2.4.19 with acpi-20020918 is running quite smoothley except for some problems 
with the battery state:
 
---- fragment of /var/log/messages: 2.4.19 + acpi20020918 + gentoo patches 
---------

Now I compiled a new kernel 2.4.20 with the acpi kernel patch-20021212 and 
ACPI does not work anymore. :-( 
"ACPI: Found ECDT
ACPI: Could not use ECDT"
How comes? If it is of any help to you I would provide further information 
(log messages, etc.) regarding this issue. Thanks in advance for any help!

It must be (well) known, but I don't have precise information. Please
check out the ML archive for ECDT support status in the latest code. You
can surely find out the right answer with full description.

# FWIW, any version of Windows aren't yet __fully__ ACPI 2.0 compatible
so far, and they simply ignore ECDT if present.

ACPI is completely disabled for IBM Thinkpad A31. Is there a solution for that

In short, ECDT -> EC_ID is supposed to be the full path name of your EC
device in ACPI Namespace like "\_SB.PCI0.LPC.EC", but __NOT__ in your
BIOS. 
You can work around your problem by adding hack code, but it makes OS
code dirty to save broken BIOSes and it allows BIOS vendor not to fix
their problem.

Re: Re: IBM Thinkpad A31 | ACPI problems

[Dom]

Dear Kenichi,

sorry - i did not see Andy Grover's reply to Sandro earlier on. So the problem 
is a bug in the BIOS implementation. I have already contacted IBM via "Ask an 
expert" and posted a message to http://www7.pc.ibm.com/~Thinkpad and I really 
hope that they will reply. I will keep you up to date.

Thanks,
Dominik

p.s. How ugly would a work around for the BIOS problem be? Aren't there 
already several work arounds for buggy BIOSes in the Linux kernel code?

Hi,

i'm also encountering the same problems with my (beloved ;) ) A31. So if there 
is a possible workaround - is anyone already working on it/how difficult 
would it be to implement such that hack?

Uh!
I didn't know that IBM has a forum. Where is your question located (I can't
find it)? Can you please email me if you find a solution for the whole prob?
I also questioned IBM about that prob a few days ago, but via support - no
answer so far.

Dear Sandro,

I posted the following message to the "Thinkpad A20,A21,A22,A30,A31" forum at 
IBM. Currently it looks like the posting has not been opened to public yet? I 
hope that IBM will provide a patch or that we can assist in creating a work 
around for the buggy bios. I know several friends who are running Linux on 
their A31's. Currently we all stick to kernel 2.4.19 + acpi-20020918 patch. 
This combination provides at least some support for ACPI. 

Thanks to the hard-working acpi-development team!
Dom

Hi all!

I am successfully running Gentoo Linux
(http://www.gentoo.org) on my new A31. Unfortunately
ACPI is not getting initialized properly with the new
acpi-patch from 20021212 ( + vanilla 2.4.20). I consulted
the acpi developers (http://acpi.sf.net) who told me that the
problem is the buggy BIOS! Is IBM aware of that problem
and are there any ongoing efforts to solve this problem?

Thanks!
Dom

Hi Thinkpad dudes out there,

1.) the following message was posted by an IBM employee on

Hello Dom,
Unfortunately, we do not have any information on whether or not the BIOS will 
be updated to resolve the issue you are having with the ACPI. This is up to 
the IBM Software Developers.
 
Thank you for choosing the IBM Forums.

Dear Mr. Bar,
you have contacted the technical support of IBM and we can't give you
marketing informations about future equipment. Please call our service
centre at 01803 - 31 32 33 and ask for someone who is able to inform you
about that.

Hmm ... if it turns out that IBM does not fix their BIOSes, I will have
to start advising people against buying Thinkpads. Period.

Perhaps we should find a way to make this very clear to IBM, and to
the other companies who think they will get away with not doing their
homework -- and of course to all potential buyers.

Nobody wants to give up their freedom, so the inability to run Linux on
a newly bought machine is something that will even annoy many of those
who are currently only interested in Windows.

IBM Thinkpad A31 | ACPI problems

[Dom]

Dear Hubert!

According to the Linux ACPI developers the IBM Thinkpad A31 has a buggy BIOS. 
Recently I have heard/read rumors that SuSE is cooperating with IBM 
concercing the ACPI implementation of Thinkpad notebooks. There seem to be 
many Thinkpad owners having the same problem with ACPI support. 
Today I have tested your SuSE kernel (suse-2.4.19-41 [20030103]) hoping that 
ACPI might work. ;-) Could you please inform us what the status of the 
cooperation with IBM at SuSE is? Are there any efforts at IBM to fix the 
buggy BIOS or at SuSE to implement a work around for the buggy bios? Any 
information is highly appreciated!

Best Regards,
Dom
