L25296-001 45W 19.5V 2.31A laptop AC adapter

45W HP laptop adapter

This 45 watt AC adapter replaces part L25296-001 and matches the 19.5 volt 2.31 amp output required by many HP Pavilion and Stream models. It ships with a 4.5 by 3.0 millimetre blue tip connector and a detachable mains cable. The unit accepts 100 to 240 volt input at 50 to 60 hertz for worldwide use. Buyers needing higher wattage or a different tip size should look elsewhere.

Plug-in replacement

Installation is limited to connecting the barrel plug to the laptop and the IEC lead to a wall socket; no tools or drivers are involved. The most common issue is selecting a unit with the wrong tip polarity or diameter, which prevents charging. Verify the 4.5 by 3.0 millimetre centre-positive specification before ordering.

Steady 45 watt delivery

Under continuous load the adapter maintains its rated 19.5 volt output without voltage sag, keeping the battery charging while the system runs typical productivity workloads. Thermal protection shuts the unit down if internal temperatures exceed safe limits, after which it restarts automatically once cooled. It is not designed for sustained loads above the 45 watt rating.
