Hi Rafael Thanks, I am testing ZPODD function ,for Linux ZPODD kernel, if _PRW method is removed at BIOS ACPI DSDT codes, ZPODD work normally. but, if _PRW method is added at BIOS ACPI DSDT codes,ZPODD can't be wakeup when ZPODD state is suspend. I'am not sure that Linux ZPODD whether is using _PRW to send wakeup events. Jeff 2012/11/28 Rafael J.
