Product Identity

The HP AU656AA#AC3 is a cable lock designed to secure compatible HP docking stations and notebooks. It provides a physical tether for the 90W, 120W and 230W docking stations as well as a wide range of EliteBook, ProBook and ZBook models. This accessory suits IT teams and mobile professionals who need to deter casual theft in shared or public spaces.

Who It Suits

Buyers protecting the listed HP 90W, 120W or 230W docking stations and compatible EliteBook, ProBook or ZBook notebooks will find a matching lock slot. It does not fit devices that lack the required security slot, so buyers needing to secure ultra-thin laptops, tablets without a lock slot or non-HP hardware should look elsewhere.

Deciding Specification

The lock works only with the specific HP docking stations and notebook models enumerated in the compatibility list, including the 90W, 120W and 230W docks and EliteBook series such as 820, 840, 850, 1020, 2170, 2540, 2560, 2570, 725, 745, 755, 810, 8460, 8470, 8570, 8760, 8770 and ProBook series such as 640, 645, 650, 655, 6440, 6445, 6450, 6455, 6470, 6475, 6540, 6545, 6550, 6555, 6570.

Questions about this item

Will this lock fit the 90W and 230W docking stations I already use with my EliteBook 840 G2?

The lock is compatible with the 90W, 120W and 230W docking stations listed, so it will secure both your existing docks.

How can I confirm the lock is properly engaged on the docking station after I attach it?

Insert the lock into the dock's security slot, turn the key and verify the cable cannot be pulled free; the key only removes when the mechanism is fully locked.

Does the package include the lock, keys and cable, or must I buy the cable separately?

The AU656AA#AC3 ships as a complete cable lock assembly with keys included; no extra cable purchase is required.
