+This mini-driver drives the SNC and SPIC device present in the ACPI BIOS of the
+Sony Vaio laptops. This driver mixes both devices functions under the same
+(hopefully consistent) interface. This also means that the sonypi driver is
+obsoleted by sony-laptop now.

 
 

-It gives access to some extra laptop functionalities. In its current
-form, this driver let the user set or query the screen brightness
-through the backlight subsystem and remove/apply power to some devices.
+Fn keys (hotkeys):
+------------------
+Some models report hotkeys through the SNC or SPIC devices, such events are
+reported both through the ACPI subsystem as acpi events and through the INPUT
+subsystem. See the logs of acpid or /proc/acpi/event and
+/proc/bus/input/devices to find out what those events are and which input
+devices are created by the driver.
