The DSDT describes a FUNC interface that exposes currently unused functionality. This patch adds 3 read-only files to the platform device containing docked, lid & radio state. Please test whether this returns appropriate information on your specific laptop. Also, please enable debugging and supply me with: - your exact laptop type (such as Lifebook S6420) - the icons on your 4 application panel buttons - your BTNI value (such as 0xff0101) - your LEDI value (such as 0x100) - your DSDT, available from /sys/firmware/acpi/tables/DSDT Regards, Tony V. P.S. Apologies if you got a duplicate message, the mail didn't seem to have made it out to linux-acpi after 6 hours.
