45W 19.5V AC adapter with 4.5mm blue tip

This 45 watt AC adapter delivers 19.5 volts at 2.31 amps through a 4.5 by 3.0 millimetre blue tip connector. It accepts 100 to 240 volt input at 50 to 60 hertz and includes a three prong AC power cord. The unit replaces HP part numbers such as 719309-001 and ADP-45WD B for compatible HP laptops.

Capacity and headroom for 45 watt HP systems

The adapter supplies the full 45 watts required by supported HP Stream, Pavilion x2, Spectre x2 and EliteBook Folio models. It will run out of headroom on any device that draws more than 45 watts or requires a different voltage or connector size. Buyers needing higher wattage or a different tip should select another adapter.

Thermals noise and power draw in normal use

The adapter operates from standard mains voltage and draws only the power needed by the connected laptop up to its 45 watt limit. No fan is present so operation is silent. Heat output remains low during typical charging and usage scenarios.

Questions about this item

Will the 19.5V 2.31A output charge an older HP EliteBook Folio 1040 G1 that originally used a 45W adapter?

Yes, the adapter delivers 19.5V at 2.31A for 45W total, matching the original 45W requirement of the EliteBook Folio 1040 G1, and the 4.5*3.0mm blue tip fits the charging port.

How can I confirm the 45W adapter is working correctly after connecting it to my HP Stream 13?

The laptop charging indicator should light up and the battery icon will show it is receiving power; the adapter accepts 100-240V 50-60Hz input so it works on any mains supply.

Does the package include both the AC adapter and the mains power cord, or must I buy the cord separately?

The box contains one AC adapter and one AC power cord, so no separate cord purchase is needed.
