One Dock for Office and Remote Work

The included 90 W power adapter delivers up to 65 W to most USB-C notebooks while running the dock and its connected peripherals. For 100 W charging a separate 135 W slim-tip adapter (PN 4X20E50558) is required.

Questions about this item

How do I connect the dock so the laptop actually charges, and what is the step people miss?

Plug the supplied 90 W adapter into the dock, then connect the dock to the laptop with the USB-C cable; the step often missed is that the 90 W adapter only delivers up to 65 W to the notebook — for 100 W charging you must buy the optional 135 W slim-tip adapter (PN 4X20E50558) separately.

What part will need replacing first if I want full 100 W charging later?

The in-box 90 W power adapter limits charging to 65 W; to reach 100 W you must purchase the separate 135 W slim-tip adapter (PN 4X20E50558).

What power limit appears first during sustained heavy use with the included adapter?

The included 90 W adapter caps notebook charging at 65 W, so the power delivery ceiling is reached before any thermal or data-throughput limit.
