Product purpose
The Lenovo ThinkPad Basic Dock 90W (40A00090US) expands connectivity for compatible ThinkPad laptops through a single proprietary connector. It provides a 90W AC adapter, one USB 3.0 port, three USB 2.0 ports with one always-on charging port, a VGA output for a single external display, and a wired Ethernet connection. The dock is designed for office workers who need a simple desk setup with legacy monitor support and wired networking.
Who it suits and who it does not
This dock suits owners of listed 65W and 90W ThinkPad models such as the T440, T450, T460, T470, T540p, T550, T560, T570, X240, X250, X260, X270, L440, L450, L460, L540, L560, L570, P50S, P51S, W550s and ThinkPad 25. It does not suit buyers who need multiple external monitors because the VGA port supports only one display. It is not recommended for laptops that ship with a 170W AC adapter, as the included 90W supply cannot meet their power requirements.
Bundled accessories impact
The included 90W ThinkPad AC adapter powers both the dock and the connected laptop, removing the need to carry the original charger. The always-on USB 2.0 port charges phones or accessories even when the laptop is undocked or asleep. The driver-free VGA output works immediately with older projectors and monitors, while the Ethernet port adds a stable wired network link without extra configuration.
