90W AC adapter for HP laptops

This 90 watt power supply delivers 19 volts at 4.74 amps and includes a 5.0 by 7.4 millimetre smart-pin connector. It replaces original chargers for a wide range of HP Pavilion, EliteBook and ProBook models. Buyers who need a higher wattage unit or a different tip size should look elsewhere.

Thermals noise and power draw

The adapter accepts 100 to 240 volt input at 1.8 amps and operates at 50 or 60 hertz. It runs without a fan so operation is silent. Built-in protection guards against short circuit, over-voltage, over-current and internal overheating during normal use.

Included power cable and smart-pin

A mains cable is supplied in the box so the charger is ready to use immediately. The central smart-pin communicates with compatible HP notebooks to confirm correct power delivery. Systems without the smart-pin interface will not benefit from this handshake.

Questions about this item

How do I install the 5.0/7.4mm smart-pin connector on my HP EliteBook 840 G1, and what step do people miss?

Align the centre pin with the socket before pushing the 5.0mm inner / 7.4mm outer barrel home; the step most users miss is seating the smart pin fully so the laptop recognises the 90W rating.

What maintenance or replacement will this 19V 4.74A adapter need later?

The detachable mains lead (100-240V 1.8A 50/60Hz) is the only user-serviceable part; the sealed 90W brick itself has no replaceable components.

What limit appears first when this charger runs continuously at 90W?

Internal overheating protection activates before any other limit, shutting the unit down until it cools.
