ACPIDOCK(4)              BSD Kernel Interfaces Manual              ACPIDOCK(4)

NAME
     acpidock -- ACPI docking station

SYNOPSIS
     acpidock* at acpi?

DESCRIPTION
     The acpidock driver supports ACPI docking stations.  Docking stations are
     units that, for example, laptops may attach to in order to expose a num-
     ber of additional hardware devices.  The acpidock driver handles docking
     and undocking machines to gracefully detach external devices.

     When docking and undocking, an event is passed to the driver which is
     then reacted upon.  For undocking, this event is usually triggered by
     pressing a button on the docking station or using a special keyboard com-
     bination; for docking, the machine usually just has to be inserted.

     The acpidock driver sets up a sensor that indicates docking state that
     can be used with sensorsd(8) to perform events when docking or undocking.
