The most common problems with the Vertical Docking Station for the 2012-2015 MacBook Pro are generally caused by port misalignment.
The docking station holds the connector end of the cables in place using a series of setscrews that apply pressure. Occasionally they can be shipped at the incorrect height or get pushed out of alignment due to misuse. It is incredibly easy to fix and only takes a few moments.
Step 1. Unscrew the cover anchor and remove the screw cover
Step 2. With the MacBook removed from the docking station, loosen setscrews and remove all cables from the docking station.
Step 3. Reconnect your peripherals directly using the now removed extension cables to test connectivity.
- If everything connects correctly, move on to step 4.
- If one or more of the extension cables does not work, skip the remaining steps and click the Contact Us button at the bottom of the page. Please detail which cables specifically are not working and the device(s) (brand and model) you are connecting it to.
Step 4. While seated, place MacBook into the empty dock, and flip them over as one unit, holding it in your lap. Reinstall each cable individually, through the corresponding port voids and into the MacBook. Slide the cables into the cable organizer at the back of the docking station.
Step 5. Carefully flip the computer over, placing the unit on a flat, stable surface. With all cables in place, tighten the setscrews, realign the screw cover, and secure the cover anchor.
Please note: Do not over-tighten the setscrews. Permanent connector damage can result from over-tightening. Minimal pressure is required to hold the cable heads in the docking station.
