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. > and a bit off topic, what exactly can i do with the > embedded_controller entry i have in my /proc/acpi ? it just shows up > an info file ? That's OK, AFAIK the embedded controller does not provide any interface to userspace you could play around with. Thomas P.S.: you should CC the list again, so that others with similar problems grepping the archives or googling know what to do. ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
