Section 6.1 of the ACPI specification states: 'The _PTS control method provides the BIOS a mechanism for performing some housekeeping, such as writing the sleep type value to the embedded controller, before entering the system sleeping state'.  Hence _PTS is provided for the firmware to do housekeeping and therefore does not appear to be mandatory.  In this case, the platform seems to have omitted _PTS because it may not need it.  Unfortunately the kernel complains about this not existing. This is most probably not an error.",
