45 W 19 V laptop charger

This 45 W AC adapter delivers 19 V at 2.37 A through a 4.0 x 1.7 mm barrel connector. It matches Chicony part numbers A18-045N2A and A045R086P for direct replacement. The unit is supplied new and ready for compatible laptops. Buyers who need a different voltage, amperage or tip size cannot use this model.

Thermals noise and power draw

The adapter draws up to 45 W from the mains under full load and runs silently with no moving parts. Normal operation produces low warmth that stays within typical external power-supply limits. No fan noise is present because the design is passively cooled. Users requiring higher wattage for larger laptops should select a different unit.

Questions about this item

How do I connect the 4.0 x 1.7 mm barrel plug to the laptop's DC jack?

Align the centre pin with the jack's socket, push straight in until it seats firmly, then route the cable so the adapter brick rests on a flat surface without tension on the cord.

When should the 45 W adapter be replaced?

Replace it if the output drops below 19 V 2.37 A, the brick becomes unusually hot, the cable shows exposed wires, or the connector feels loose in the jack.
