What this adapter replaces

This 45W AC adapter supplies 19.5V at 2.31A through a 4.5*3.0mm blue-tip connector. It matches HP part numbers including 719309-001, 740015-001 and HSTNN-DA35. The unit is built for HP Pavilion, Envy, Spectre x360 and Split x2 models such as 14-ax040wm, 15-f272wm and 17-g121wm.

Thermals, noise and power draw

The adapter accepts 100-240V input at 1.3A, 50/60Hz and delivers a steady 45W output. Overheating protection and short-circuit protection are integrated. No moving parts are present, so operation is silent. The two-plug mains lead is included in the package.

The connector that decides fit

Only laptops that use the 4.5*3.0mm blue-tip barrel can use this supply. Dell XPS13 and any device with a different tip size or polarity will not connect. Check the original charger tip before ordering.

Questions about this item

How do I install the 4.5*3.0 mm blue-tip connector on my HP laptop?

Align the blue-tip connector with the laptop's DC-in port and push straight in until it seats firmly; the step people miss is verifying the 19.5 V 2.31 A 45 W output matches the original adapter's label before powering on.

What maintenance or replacement will this 45 W adapter need later?

The detachable 2-plug power cord can be swapped if the IEC C7 lead frays; the adapter body itself has no user-serviceable parts and is replaced as a unit if the 100-240 V input or 19.5 V output fails.

What limit appears first under sustained use of this 19.5 V 2.31 A supply?

Continuous full-load operation at 45 W will hit the built-in overheating protection before any other limit, causing the adapter to shut down until it cools.
