150W AC adapter for HP ZBook and Omen laptops

This 150W charger supplies 19.5V at 7.7A through a 4.5mm by 3.0mm blue-tip connector. It replaces part numbers including L48757-001, TPN-CA11 and 917649-850 across HP ZBook 15, 16 and 17 series from G3 to G8, ZBook Power G7 and select Omen 15 and 17 models. The package includes the adapter and a detachable power cord.

Thermals, noise and power draw

The unit delivers up to 150W and is also compatible with 135W and 120W requirements, drawing only the power the laptop requests. Built-in protections guard against short circuit, overvoltage, overcurrent and internal overheating. No fan is present, so operation is silent.

Build integration

The blue-tip barrel plug fits the listed HP models directly without adapters. A standard IEC C5 cloverleaf cord is supplied for wall connection. Buyers whose laptops use a USB-C or a different barrel size cannot use this adapter.

Questions about this item

How do I connect the 4.5 mm 3.0 mm blue tip connector to my HP ZBook?

Align the blue tip with the charging port and push straight in until it seats firmly; forcing it at an angle can bend the centre pin.

Which parts of the TOPRANK L48757-001 charger will need replacement over time?

The detachable power cord and the blue tip connector see the most wear; replace either if the cord frays or the tip becomes loose.

What limits the charger during long gaming sessions on a ZBook 17?

Internal overheating protection activates first under sustained 150 W load, throttling output until the adapter cools.
