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
