280W HP Workstation Charger

This 280W AC adapter replaces the original power supply for select HP ZBook Fury and Studio mobile workstations plus OMEN 16 laptops. It delivers 20V at 14A through a 4.5mm by 3.0mm barrel connector and includes a detachable AC power cable.

For HP ZBook and OMEN 16 owners

Buyers with a compatible ZBook Fury G9, ZBook Fury 15.6 G8, ZBook Studio 16 G9, ZBook Studio 15.6 G8, OMEN 16t-k000 or OMEN 16-n0797nr can use this unit as a direct replacement. Laptops that require a different connector size, a lower wattage rating or a USB-C power input will not work with this adapter.

20V 14A barrel output

The single specification that determines fit is the 20V 14A output on a 4.5mm x 3.0mm centre-positive barrel plug. If the original charger for your machine matches those electrical values and the physical tip, this part will power it.

Questions about this item

How do I install this 280W adapter and which step do people get wrong?

Connect the AC cable to the brick, plug the barrel into the laptop's 4.5mm x 3.0mm port, then switch on mains power; the common error is inserting the barrel upside-down, which prevents the 20V 14A output from engaging.

What maintenance or replacement will this power supply need later?

The detachable AC cable is the only wear item; replace it if the plug or insulation is damaged, otherwise the sealed 280W brick requires no user maintenance.

What limit appears first when this charger runs continuously at full load?

Thermal protection will trip if the 280W unit cannot dissipate heat; keep ventilation clear so the 20V 14A output stays stable during sustained use.
