# acpidock(4)

ACPI docking station

## 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 number 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 combination; 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)](/sensorsd/8.md) to perform events when docking or undocking.
