Docking apparatus

A docking apparatus includes a port replicator, a base for supporting the port replicator thereon, a fixing member, a resilient member, and a button. An accommodating hole is defined in the port replicator, and a hole is defined in the base corresponding to the accommodating hole of the port replicator. In use, the resilient member drives the fixing member upwardly to extend through the hole of the protrusion to engage in the accommodating hole of the port replicator thereby fixedly attaching the port replicator to the base. The button is to drive the fixing member to retract from the accommodating hole of the port replicator to release the port replicator from the base.
