I have a Dell Optiplex GX270. When I grep the dmesg I get the error that this bug report shows.
I then did this: ~ sudo cp /proc/acpi/dsdt . ~ sudo iasl -d dsdt ~ sudo iasl -sa dsdt.ds After it compiles I get this Warning: dsdt.dsl 1052: Method (_S5D, 0, NotSerialized) Warning 1097 - Unknown reserved name ^ (_S5D) ASL Input: dsdt.dsl - 3213 lines, 108415 bytes, 1051 keywords AML Output: dsdt.aml - 9858 bytes 394 named objects 657 executable opcodes Compilation complete. 0 Errors, 1 Warnings, 0 Remarks, 257 Optimizations I tried tracking down "Method (_S5D", but couldn't find anything. I get close but no cigar. -- ACPI: Looking for DSDT ... not found!
