Hey Folks,
i have an ProBook 455 G9 with Ryzen 7 as my Work Notebook. For better Desk-Cable-Management i've tried to Charge it with my USB-C Charger. As the Manual and the Specs said, it would support USB-C Charging with PowerDelivery Standard. I've Tried several different Chargers - From 20W to 60W, all with PD Support, different Cables - nothing. I've also Tried my Charger fom my Nintendo Switch - this one works Fine on my Surface.
The Charging-LED flashes in White when connected to the USB-Charger, but won't start Charging. What should i Do? What USB-C Chargers can you suggest?
My Plan is to Connect my USB-C Hub, to Charge the Laptop and connect my two Monitors through HDMI.
Thanks for your Help!

Please use a list of AC Adapters on page 24 of the following manual

Hello.
If your product came with a 65W adapter, there's a valid reason for it. Laptops are not "trickle" charged, so 20W or 60W Power Delivery will not do.
Turn your laptop upside down and take a look at the small text printed there. There should be two different voltages requirements, for 19.5V and 20V input. The 19.5V input is for the round power connector. The 20V input is for USB-C Power Delivery. Your charger must have the same or higher Amp rating as specified by your laptop for the 20V.
The page 25 in the mentioned manual contains HP docks that should work, but practically any 3rd party USB-C dock should work with your laptop, because USB-C with Power Delivery is an industry standard. Just make sure it is not Thunderbolt model because your laptop doesn't have TB, and make sure it has adequate Power Delivery output.
