About this docking station
A docking station lets a laptop link to monitors, wired networking, keyboard, mouse and mains power through a single cable or connector, so the whole desk arrangement is ready as soon as the laptop is attached. Docks vary in how they connect, in the screens and charging they can handle, and in the sockets they provide. Trouble shows as video, network or USB connections failing through the dock, charging that stops, or the laptop no longer detecting the dock at all. Updating the dock firmware often resolves such faults.
Is this the right part?
Look at the label on the base for the model and part number. Before ordering, compare how it connects with your laptop, the charging power required, and the screens it can drive, including their resolution. The manufacturer's part number for this listing is 40A20090SA.
Not sure? Send us the number from the label, or your machine's serial number, and we will confirm the match before you order.
