Check your laptop model

Verify that your HP 14-inch laptop appears in the supported model list, which includes examples such as 14-DK0020nr, 14-DQ1035CL, 14-DF0023CL and 14-FQ0036cl among many others. Confirm the original charger uses a 4.5 mm by 3.0 mm blue-tip barrel connector. Ensure you need a 45W unit rated at 19.5V 2.31A rather than a higher or lower wattage adapter.

Replaces HP part numbers 719309-003.

This adapter serves as a direct replacement for those three HP part numbers. The upgrade is worth it when the original charger is lost, damaged or no longer holds a stable charge. Buyers needing a different connector size, higher wattage or USB-C power delivery should look elsewhere.

Questions about this item

Does the 45 W adapter include a mains cable or just the brick with its 4.5×3.0 mm blue tip?

The unit ships as a complete 3-plug assembly so the detachable mains lead is already in the box; no separate cable purchase is needed.

My HP 14-dq1035cl needs 19.5 V 2.31 A — is this the only 45 W version listed or are there higher-wattage options?

This listing is the single 45 W model rated at 19.5 V 2.31 A; no other wattage variants appear in the compatible-part data.

Will the 19.5 V 2.31 A output actually deliver 45 W continuously in a 14-dk0020nr without overheating?

The adapter is UL listed and rated for 100-240 V 1.3 A input, so it is designed to supply the full 45 W steadily under normal laptop load.
