Devices connected to the USB ports on the dock were also instantaneously recognized. The docking station’s cable fit snugly into the notebook’s OneLink port, and upon connection was immediately recognized by Windows 7 64-bit. But Lenovo points out that the OneLink port has specific benefits over Thunderbolt: for starters, it delivers not only data, but also power, and it’s also much less expensive.įor our tests in this article, we used a Lenovo ThinkPad Edge E431 (configured as detailed in our review here). After all, we’ve already got Thunderbolt, and had they chosen to use that technology instead, the dock would be compatible with any PC with a Thunderbolt port. Lenovo’s proprietary OneLink interface might seem like a confusing choice at first. In this review, we’ll test the device to see whether or not it can perform to specifications without taxing the workstation to which it’s connected. Lenovo claims that the OneLink Dock is 70% more efficient than the previous USB 3.0 dock technology. With four USB ports (two of which are USB 3.0), HDMI, audio, and Gigabit Ethernet, it’s all most users will likely need. New ThinkPad Edge notebooks now come equipped with this special port, which handles both power and data-and these are the only notebooks which are currently compatible with the dock. The ThinkPad OneLink Dock-thanks to the proprietary port by the same name-is the solution. While USB docking stations are better than nothing, there are notable drawbacks to the approach: specifically, CPU usage and data compression, both of which can affect the performance of the workstation and quality of the resulting output. What’s a ThinkPad without accessories? Business users have long relied on their ThinkPad docking stations to both simplify and expand their connectivity at the office or home, but until now, ThinkPad Edge users have been left to deal with USB-based solutions.
