The ThinkPad OneLink Docking Station in Midnight Black transforms your new ThinkPad from a productivity powerhouse in the office to a multimedia supercentre at home. Not only does the convenient OneLink connector deliver super-fast data transfers with USB 3.0 and crystal-clear HD audio and video, but it also charges your notebook, mobile phone and tablet while you work or play! This laptop docking station includes a 65 W power adapter which can power both the dock and your ThinkPad. It is ideal for use with most USB devices, including printers, keyboards and mice, as well as memory keys, hard drives and other quick-access devices. The beauty of Lenovo's OneLink technology is that it delivers data, driver-free video and power through a single convenient connector. Unlike USB docks, the OneLink Docking Station delivers video with no compression, no drivers and no impact on image quality or notebook performance. There are 2 USB 3.0 ports on the front panel of the docking station and 2 USB 2.0 ports on the rear panel of the dock. There is also a Stereo/Mic Combo Audio Port on the rear panel as well as HDMI, Gigabit Ethernet (10/1000) and DC Power ports. The cable lock slot located on the side of the ThinkPad OneLink dock offers a way to physically secure the dock to your workspace or desktop.
