FOOTNOTES [Δ]
  1. Any model that is powered-on and attached to this docking station will shut down immediately, due to a stray electrostatic discharge that is caused by insufficient insulation. The solution to this problem, is to either turn off the laptop and dock it, or attach two rubber caps (FRU: 42W3219/42W3220) on two of the furthest 'EMI fingers' located on the docking station. More information regarding this problem can be found here.
  2. This port will not work on models with a GMA 900, as it does not support any form of DVI output.
  3. This port will be inactive on models equipped with the Switchable Graphics feature, unless the Radeon HD 3470/3650 is enabled and is in use. This is due to the DVI connection being wired to only accept output from the dedicated GPU.
  4. If the docking station loses AC power (from the AC adapter), these ports will cause the attached laptop to soft-lock. You can prevent this from occurring by disabling the serial and parallel port in the BIOS (Config > Docking Station > Legacy Devices on Mini-Dock > Disabled). There is no official fix, even Lenovo themselves state that this is the only way.

Overview

This docking station is capable of accepting an 'extender' (FRU: 42W3365/42X4884) that seems to be meant for supported 14.1-inch widescreen models. The purpose of this extender is to function as a wrist-rest/palm-rest, as the 14.1-inch widescreen models do not have sufficient coverage to act as a wrist-rest/palm-rest.
