Battery Status on Acer Extensa 4101

Hello again,

well - no one replied to my last mail, so I'll post again with the current 
status. :-) The ACPI errors on boot continue to appear, however the only 
thing which isn't working is to get the status of the battery. I can see it 
in /proc/acpi/battery/BAT1/state but it says:

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

I tried to use the sbs-cm patches but they don't apply to my DSDT (actually, 
the DSDT doesn't even compile with the IASL without any patches. :-(). I then 
tried to use the program smartbatt which only needs a small kernel patch 
(acpi-ec-2.6.10.diff which applies cleanly to my 2.6.11.3) and then tries to 
access the battery using i2c. However there are no i2c busses detected!

bash-2.05b# ./smartbattery
Error: No i2c-bus specified!
Syntax: smartbatt I2CBUS
Error: No I2C busses found!
Be sure you have done 'modprobe i2c-dev'
and also modprobed your i2c bus drivers

I did load the modules of course. Does anyone have an idea how I could get the 
state of my battery?

It wont work: there isn't a smartbattery susbsystem declared in that DSDT

That DSDT is buggy for sure, but Im not sure its the original one.

I cant debug anyway.  I need a full acpidump (there are SSDT) and I got only
a decompiled DSDT from your previous mail.


wget ftp://ftp.kernel.org//pub/linux/kernel/people/lenb/acpi/utils/pmtools-20031210.tar.bz2
tar xjvfp pmtools-20031210.tar.bz2
cd pmtools-20031210/acpidmp
make
sudo ./acpidmp > acpidmp.out
bzip2 acpidmp.out 

Then mail me the acpidmp.out.bz2

Cheers,
