What this adapter replaces

The Graviton TPN-LA10 is a 230W AC adapter built for HP OMEN 17 and ZBook 15 G4 laptops that require 19.5V at 11.8A. It matches part numbers TPN-LA10, TPN-DA12, PA-1231-08HT, PA-1231-66HH, 924942-001, 925141-850 and L38011-003. Buyers needing a different voltage, a higher wattage or a USB-C power solution cannot use this unit.

Thermals noise and power draw

The adapter accepts 100-240V input at 50-60Hz and delivers a steady 19.5V 11.8A output rated at 230W. It carries CE certification for electrical safety. No active cooling or fan is described in the specifications, so operation is silent. Users who need efficiency data, standby power figures or thermal limits under sustained load will not find them here.

Build connectors and daily use

The barrel plug measures 7.4mm outer diameter by 5.0mm inner diameter with a centre pin. The package includes one AC adapter and one power cord with EU, US, UK and AU plug options. The cord is fixed to the adapter body, so a damaged cable means replacing the whole unit. Travellers who prefer a detachable IEC lead or a smaller GaN form factor should look elsewhere.

Questions about this item

How do I connect the 7.4*5.0mm centre-pin plug to my HP OMEN 17 and which step do people get wrong?

Align the 7.4 mm outer barrel and 5.0 mm centre pin with the laptop socket, push straight in until it clicks, then plug the IEC C5 cord into the brick and the wall. The common mistake is inserting the plug at an angle, which bends the centre pin and stops charging.

What maintenance or replacement will this 230 W adapter need over time?

The detachable IEC C5 power cord is the only user-serviceable part; replace it if the insulation cracks or the plug loosens. The sealed brick itself has no fan or filters, so no internal maintenance is required — if output drops below 19.5 V or 11.8 A under load, replace the whole unit.

What limit appears first when this adapter runs at full 230 W for long periods?

Thermal protection triggers first. Sustained 19.5 V at 11.8 A heats the sealed case until the internal over-temperature circuit cuts output; the adapter restarts once it cools. Adequate airflow around the brick delays this limit.
