Product identity

This 45W AC adapter supplies 19.5V at 2.31A through a 4.5mm by 3.0mm blue-tip connector. It is built for owners of compatible HP 15 and 17 notebooks who need a replacement or spare charger. The unit accepts 100-240V AC input at 1.3A and includes short-circuit protection. A power cord and manual are supplied in the package.

Power capacity and limits

The adapter delivers 45W continuously, matching the original supply rating for the listed HP models. It will run the laptop and charge the battery simultaneously under normal workloads. Heavy sustained loads that demand more than 45W will exceed the adapter's capability and may cause throttling or shutdown. The 20V 11.8A 85W figures shown in some data fields belong to a different unit and do not apply here.

Thermals noise and draw

With no fan the adapter operates silently in typical use. The brick warms noticeably when the laptop draws close to the full 45W but stays within normal limits for a sealed wall-wart design. Input current peaks at 1.3A from a 100-240V 56-60Hz mains supply. No active cooling or audible noise is present under standard office or home conditions.

Questions about this item

Will the 4.5×3.0 mm blue-tip connector fit the charging port on my HP 15-ay039wm?

Yes — the adapter uses a 4.5 mm outer / 3.0 mm inner blue tip that matches the barrel port on every listed HP 15 and 17 model, including the 15-ay039wm.

How can I verify the 45 W adapter is delivering 19.5 V / 2.31 A after I plug it in?

The unit has no built-in meter; use a multimeter on the barrel tip to confirm 19.5 V DC and check that the laptop battery icon shows charging at the expected rate.

What ships in the box and what must I supply myself?

The package includes the 45 W power adapter, a detachable AC power cord (Type-A 2-pin NA) and a product manual; no other cables or accessories are required.
