DSDT problem with Acer Aspire 3002NLC

Hi!

I have a Acer Aspire 3002NLC and the battery was not getting reported. The syslog too was flooded. I checked up the DSDT database and found a fixed table for Aspire 3000 (It reportedly fixed this error, see
http://acpi.sourceforge.net/dsdt/view.php?id=377). I merged the changes with the decompiled file I had. I had decompiled with iasl, and on recompilation with the patch 6 errors remained. (Originally 37 errors were present). I am using iasl version 20050513.

The compilation cmdline: iasl -oi -of -on -tc dcust.dsl 2>&1 > /tmp/error.log

Error log:

Thanx,

PS: I am new to the list. Tried attaching the dsdt, but the mailist list server complained. So, I have mailed without the dsdt (I think it's the same as in the url above). If the older mail eventually gets approved and comes to this list, sorry for the repetition :)

is probably the day they start making vacuum cleaners.

The object is defined in your SSDT.
Try adding:
External (\_PR.CPU0._PPC)
in global scope
or
External (_PPC)
in the \_PR.CPU0 scope.
One of these should work getting your dsdt compiled.
The kernel interpreter will find the object when the SSDT table is loaded.

Don't know whether the .hex file of a DSDT compiled with errors is valid.

Adding the External (...) statements?
No this doesn't fix anything.
It's just a hint for the compiler that these objects are in a separate table.
You can do:
acpidmp > /tmp/acpidmp
acpixtract ssdt /tmp/acpidmp > /tmp/ssdt
(be careful there could be more than one, maybe you have to split the /tmp/acpidmp outputfile (it's a text file, you can just copy away several SSDT.... parts) to e.g. /tmp/ssdt1 /tmp/ssdt2).
iasl -d /tmp/ssdtX
There should somewhere exist the \PR.CPU0._PDC object the compiler complained about.

However your dsdt/ssdt(s) seem to work well.
I expect your battery to be a smart battery system, for which an instruction exists to get it going. It includes patching your DSDT with some additional instructions.

If you grep the archives you should find a step by step instruction. IIRC Rich Townsend posted it, at least he did this smart battery stuff.

That's OK, AFAIK the embedded controller does not provide any interface to userspace you could play around with.

P.S.: you should CC the list again, so that others with similar problems grepping the archives or googling know what to do.
