ACPI problem with kernel 2.6.1 [Solved]

Kesereti · Guru Joined: 07 Nov 2002 Posts: 520

Almost everything works perfectly on my Gateway M350 laptop (Intel 82850 chipset), except for the battery status...for some reason, ACPI insists that I have no battery connected, even though I surely do (what *else* does it run off of when I unplug the AC adapter? =P)...the module will load nicely, and /proc/acpi/battery is created whether it's loaded as a module or built into the kernel...just nothing underneath it =\ Has anyone seen this sort of behavior before? Thanks!

Edit: This patch applies cleanly to the 2.6 kernel tree and fixes ECDT functionality for those systems that do not have a valid ECDT in the BIOS, such as my Gateway laptop (and all Gateway laptops, it seems) ... patch, recompile, reboot, and bam -- I get battery status =)

yes, same for me here, but it worked with some of the 2.6 beta kernels... :evil:

Sounds vaguely familiar

For my Gateway 200X, the problem was with the Embedded Control. Applying this patch fixed it up, but unfortunately it only works for the 2.4.x kernels. If I can get (or -hehe- cobble together) a version that works with 2.6.x, I'll post it. Did this work either of you on 2.4?

Could you post your dmesg output?

[EDIT]If you'd like to follow the bug that led up to that patch, it's here

i did not use a 2.4 kernel on my laptop but as i said it worked with the 2.6-test10 (it was test10 or 11 i think) without any problems...

heres my dmesg output:

Thanks.

It looks like you've got a different problem than I had. My battery wasn't even recognized, and I got a bunch of errors when the system tried to initialize it. Yours is definitely recognized, but you say that there is nothing under /proc/acpi/battery? That's odd. Do you still have the 2.6.0-test10 or 11 kernel lying around? Maybe comparing dmesg between the two would point to something? I'm not sure right now.

I was getting this problem with the 2.6.1 RCs, and I still have it 2.6.1-mm1. The battery status is not being shown. This leads to problems when it comes to taking my laptop off AC power (it thinks that there's zero battery charge and reboots).

Same problem!! With the 2.6.0-gentoo-r1 kernel everything works with ACPI but with the 2.6.1 series battery no longer works. I tried to compile it also as amodule but nothing change.

altair root # cat /proc/acpi/battery/BAT1/state
present: yes
ERROR: Unable to read battery status
altair root #

But with the 2.6.0 kernel it works !!!
So.. why?
Fede

There's a new MM patch. I'm hoping that it includes a fix. I'm just waiting for the ebuild to be made, and I'll be upgrading. I'll post status then.

See, the difference between that dmesg output and my own is that the battery slot is actually being detected there...mine doesn't even mention that at all -- it's as if I have no battery at all, and no place to put one =P Here's my dmesg output; I should also mention that I'm running 2.6.1-love1, which already has the mm patch added to it =)

Well, looking at other posts and whatnot, I've managed to de-compile and check the DSDT for this machine..the section for the battery control (BAT0) is in there, and it re-compiles cleanly...strange...it's also strange in that most people who have this problem also seem to have a problem with the AC adapter and thermal control, and both of those work just fine for me =\

Edit: Going to attempt to manually apply the fake ECDT patch to 2.6.1-love1, we'll see how it goes ^_^

Nope, the mm2 upgrade did not fix it for me. I'm staying away from the 2.6.1 release because my mouse is now starting to act up.

Hi,

ich hab seit dem 2.6.1 ein ähnliches Problem. Meine Anzeige ist wie folgt:

Hrm...been a while since my German classes...let me see if I can remember and translate decently (my apologies if I butcher the language, English isn't my first language either so it's kinda weird to be translating between two languages that aren't native for me ^_^):

Oh, I thought I was in the German forum!

Thanks for the translation. Zero mistakes: A+

Wow...I studied German in high school and college, but...I never really used it so I forgot a lot...or maybe less than I thought =)

yo, tassilo80, what inspiron are you using?

i got the same problem, but using 2.6.0-mm1 didn't solve it, now trying 2.6.0-gentoo and hope the best.

did you run acpi with 2.6.0-mm1 successfully?

greets,
kitano

Just got this from bugzilla:

This is good news...I tried the gentoo-sourcecs and that didn't fix it for me.

I guess it's time to wait for the mm3 ebuild.

chefakito · Posted: Wed Jan 14, 2004 9:58 pm Post subject:

I had the same problem with the 2.6.x-mmx series with ACPI and my Inspiron 8500 as tassilo80.

In the end in order workaround it, I reversed:
acpi-20031202-fix.patch
acpi-20031202.patch

That seemed to clear up the problem for me.
I submitted the bug to bugs.gentoo.org, and hopefully they passed on the bug up to who ever deals with the acpi stuff.

trapperjohn · Posted: Thu Jan 15, 2004 10:09 am Post subject:

Now THAT explains it ... I've googled around and I think I've read EVERY page out there about Inspiron 8600 and Linux and EVERYONE could read their battery status. Grr .. hope they will fix this soon.

kitano · Posted: Thu Jan 15, 2004 2:38 pm Post subject:

2.6.0-gentoo works for the battery status.
still S-modes do not work properly...

this is for dell inspiron 4000.

Unfortunately, 2.6.1-mm3 doesn't seem to solve the problem. I've got an Inspiron 8000 with two fully charged batteries, and it recognizes them, but does the same thing - it says that they are present, but all of their properties are 0.

kitano · Posted: Fri Jan 16, 2004 9:30 am Post subject:

yepp, so we gotta wait.

if somebody finds a new kernel which gives support, please post. i won't try each of the releases, takes to much time on my inspiron 4000 w 700MHz.

btw, patching the kernel myself w latest acpi-patches should solve the problem, right?
can i patch the gentoo-patched-sources? or does this end in a mess?
