Purpose and compatibility

This 19.5V 7.7A 150W AC adapter is built as a direct replacement for HP Omen 15-ax256nr and 15-ax257nr notebooks. It matches the original voltage and current ratings so the laptop charges and runs exactly as it did with the factory unit.

Sustained-load behaviour

World-wide input of 100-240VAC at 50/60Hz lets the brick operate on any mains supply without switching gear. Over-current, over-voltage, total-power and short-circuit protections engage continuously during long charging sessions, while the smart chip monitors temperature to prevent overheating under steady load.

Installation and common issues

A single barrel plug connects to the laptop and a 10 ft cord reaches distant sockets, so no tools or driver steps are required. The only frequent problem is selecting a unit with the wrong tip polarity or amperage; this model is listed as 100% compatible with the two named Omen variants to avoid that mismatch.

Questions about this item

How much heat does the 150 W adapter produce when it runs all day?

The unit includes overheating protection with a smart chip and overload protection with high-quality wires to manage thermal load during continuous use.

What must I already own to use this charger with my HP Omen 15-ax256nr or 15-ax257nr?

You need a working mains socket supplying 100-240 V AC at 50/60 Hz and the laptop itself; the 10 ft cord and connector are built into the adapter.

Will the 19.5 V 7.7 A output work safely with an older HP laptop that originally used a lower-wattage brick?

The adapter provides 19.5 V at 7.7 A with over-voltage, over-current, short-circuit and total-power protection, and is certified FCC, CE and RoHS for safe operation.
