Laptop not charging through the docking station? Check these first

Written on 5 November 2026

Does your docking station support USB-C Power Delivery?

Not every dock sends power back to the laptop, and for some models the manufacturer gives no figure. Look up the charging wattage in the dock's specification, often listed as USB-C Power Delivery. These are the figures from the specifications of six of our docks:

Does your laptop need more power than the dock can provide?

The quickest test is the label on the charger that came with your laptop. It states the output in watts. If the dock delivers less than that figure, the laptop may still charge when it is idle but fall behind once the processor and screen are working hard.

Some laptops say so at start-up. Customers have sent us Dell's start-up warning that the AC power adapter wattage and type cannot be determined. If you see a message like that on the dock, check the wattage and the brand rules below before you blame the battery.

Laptops of another brand get less charging power

Dell says in its support article on industry standard compatibility that its USB-C and Thunderbolt docks work with laptops from HP and Lenovo, and that they charge non-Dell laptops at up to 90 W. The specification of the HP USB-C/AV G2 Universal gives up to 75 W on machines that are not HP.

For a light business laptop that can be plenty. For a mobile workstation with a large charger, it may not be. Our article on whether a Dell dock works with an HP or Lenovo laptop goes into the other differences between brands.

Are you using the right USB-C port and cable?

On some laptops only one of the USB-C ports accepts charging. The user guide for your model says which one it is; plug the dock into that port.

Use the cable the dock is meant to be used with. A thin USB-C cable from a phone charger is not always rated for the current a laptop draws, and a cable that cannot carry it limits the charging power before the dock does.

When the laptop is not charging on its own charger either

Plug in the laptop's own charger. If it does not charge on that either, the dock is not the cause: the battery or the charging circuit is. A laptop that switches off the moment you unplug it points the same way. That is a question for whoever supplied the laptop, not for the dock.

Docking stations that charge your laptop

Start from the figure on your own charger and pick a dock that matches or beats it. The HP USB-C Dock G5 and the HP Thunderbolt 120W G4 both give 100 W, and the Dell WD19S gives 130 W to a Dell laptop. All our docks are refurbished, tested and sold with a two-year warranty.
