Universal USB-C Docking Station

The Lenovo ThinkPad USB-C Dock 40A9 is a universal docking station designed for compatible ThinkPad laptops and USB-C tablets. It connects through a single USB-C cable and includes a 90W AC power adapter. The dock expands connectivity with multiple video outputs, wired networking, and numerous USB ports for peripherals.

Suited for multi-display ThinkPad workflows

This dock suits users who need a single UHD display at 30Hz or dual FHD 1080p displays alongside Ethernet and peripheral connections. It supports PXE boot and Wake-On-LAN from sleep, hibernate, or power-off states. Buyers whose laptops lack a USB-C port or who require higher single-display refresh rates should consider a different solution.

60W continuous laptop charging

The dock delivers up to 60W of stable, continuous power to the connected laptop or tablet via the USB-C link. This power level determines whether the dock can keep a specific system charged under load. The included 90W adapter powers the dock and its downstream ports while reserving capacity for host charging.

Questions about this item

Does my laptop need a USB-C port that supports video and 60 W power delivery to use this dock?

Yes, the dock connects through a single USB-C cable that must carry both DisplayPort Alt Mode video and up to 60 W of charging power for the attached notebook.

Can I keep using my VGA monitor alongside two DisplayPort screens on this dock?

The dock provides one VGA and two DisplayPort outputs; you can run a single UHD display at 30 Hz or two FHD displays at 1080p, but three simultaneous monitors are not supported.

How do I confirm the dock is delivering the full 60 W to my ThinkPad after setup?

Open Lenovo Dock Manager — it shows real-time power delivery, firmware version, and device status so you can verify the notebook is receiving 60 W continuously.
