The ThinkPad Port Replicator Series 3, the ThinkPad Mini Dock Series 3, the ThinkPad Mini Dock Plus
Series 3, or the ThinkPad Mini Dock Plus Series 3 (170 W) has a security keyhole for a mechanical lock.
By attaching a mechanical lock with cable there, you can secure the ThinkPad Port Replicator Series 3,
the ThinkPad Mini Dock Series 3, the ThinkPad Mini Dock Plus Series 3, or the ThinkPad Mini Dock Plus
Series 3 (170 W) to a heavy object, such as a desk.
If you use the ThinkPad Port Replicator Series 3, and attach a mechanical lock, the eject button is also
locked, so that the computer cannot be detached from the ThinkPad Port Replicator Series 3.
If you use the ThinkPad Mini Dock Series 3, the ThinkPad Mini Dock Plus Series 3, or the ThinkPad Mini
Dock Plus Series 3 (170 W), and attach a mechanical lock, the eject button is not locked. To lock the eject
button, use the "system lock key" on page 156.
Lenovo does not offer a mechanical lock. You will need to purchase one elsewhere. You are responsible
for evaluating, selecting, and implementing any locking device and security feature. Lenovo makes no
comments, judgments, or warranties about the function, quality, or performance of any locking device or
security features.
