Power from Dock - not enough?

[123cadmaster]

This Ultra g1a is connected to a 280W thunderbolt dock via USB-C.

I realize that the USB-C is not delivering the full advertised wattage because of the barrel plug not being used.

What dock should be used with these notebooks?

Hi @123cadmaster,

Welcome to the HP Support Community!

The notification you're seeing is expected when the notebook is connected to the dock using only the USB-C connection and the notebook requires more power.

For the HP EliteBook Ultra G1a, I recommend using an HP high-power dock designed for this type of system:

Recommended dock

HP Thunderbolt Dock 280W G4 with Combo Cable

The 280W G4 can provide:

• Up to 100W through USB-C alone
• Up to 230W to support HP platforms when the 280W power supply and combo cable are used

The combo cable provides both the Thunderbolt/USB-C connection and the additional power connection, allowing the notebook to receive the higher available power.

HP also now offers the HP Thunderbolt 4 Ultra 280W G6 Dock, which supports up to 280W through its 4.5 mm power connection or up to 180W through Thunderbolt 4 on systems supporting the required PD 3.1 specification.

If you provide the exact product number of the Ultra G1a, I can verify the recommended dock and required power configuration for that specific notebook.

Best regards,
