What this adapter powers

The WAWEIS 45W AC adapter replaces the original charger for HP 15-ay075nr, 15-ay077nr and 15-ay078nr notebooks. It delivers 2.31A output and accepts worldwide input from 100V to 240V at 50Hz or 60Hz. Buyers who need a higher wattage unit or a different connector type should look elsewhere.

Thermals noise and protection

The adapter includes over-current, over-voltage, short-circuit and total-power protection circuits plus overheating protection managed by a smart chip. Anti-interference isolation materials reduce electrical noise. No active cooling fan is mentioned, so operation is silent. The unit meets FCC, CE and RoHS certification requirements.

Build and daily use

A 10 ft power cord gives ample reach from wall outlet to desk. The supplier states 100% OEM compatibility and 100% new components with strict quality control. Overload and over-charge/discharge protections help safeguard the laptop battery during everyday charging cycles.

Questions about this item

How do I install this 45W 2.31A adapter on my HP 15-ay075nr and what step do people miss?

Connect the barrel plug firmly until it clicks into the laptop's DC jack, then plug the 10 ft mains cord into a 100-240VAC 50/60Hz wall outlet; the step often missed is ensuring the connector seats fully before powering on.

What maintenance or replacement will this charger need later?

The 10 ft cord and barrel connector are the wear items; inspect them periodically for fraying or looseness and replace the unit if the smart chip's over-heating or short-circuit protection triggers repeatedly.

What limit appears first under sustained load on this 45W unit?

The 45 watt / 2.31 amp output ceiling is the first limit; continuous draw at that level activates the over-current and total-power protection circuits, causing the adapter to shut down until it cools.
