Compatibility and purpose

The HP A9B77AA#ABA 2570 Docking Station is built for 12.5-inch diagonal HP EliteBook Notebook PCs. It provides port replication for the EliteBook 2170p, 2540p and 2560p models. The dock lets you maintain connectivity and comfort at a fixed station by inserting the laptop until it clicks. It is not for owners of other notebook sizes or brands.

Connection check before ordering

Your notebook must use the proprietary host interface found on the listed EliteBook models. Verify that your unit is a 12.5-inch EliteBook 2170p, 2540p or 2560p before purchasing. The dock supplies one USB 2.0 port, three USB 3.0 ports, VGA, DisplayPort, eSATA, RJ-45 networking, audio line in, audio line out, headphone and microphone jacks. It will not connect to laptops lacking the matching docking connector.

Thermals noise and power

The docking station has no integrated cooling fans and operates silently. It draws power through the proprietary host interface from the attached notebook and its own AC adapter. Normal use adds no audible noise and minimal thermal load to the workspace. Power consumption varies with the number of active peripherals connected to the USB, video and network ports.
