The HP Docking Station Cable Lock is dramatically simpler to use than previous locks and delivers enhanced security. The HP Docking Station Cable Lock gives you two locking options: lock the docking station only (which also prevents access to the advanced docking stations drive bay) or lock both the docking station and the notebook. - Physically secure your notebook and docking station in just 3 steps. - Secure the drive bay in your HP 120W or 230W Advanced Docking Station. - Integrate into the HP Docking Station or HP Advanced Docking Station via the unique lock cavity providing enhanced security.
