What this charger replaces

This 90W AC adapter supplies 19V at 4.74A through a 5.0mm blue-tip connector. It matches the original power supply for a wide range of HP EliteBook, ProBook and Compaq models including the 8460p, 8470p, 8560p, 8760p, 4430s, 4440s, 4520s, 4530s, 4540s, 6730b, 6530b and 6560b.

Behaviour under continuous load

The unit accepts a universal 100-240V input at 50 or 60Hz and delivers a steady 90W output. This rating is designed for sustained operation while the laptop is running and charging simultaneously, rather than for short peak bursts.

Installation and common issues

Connection is a simple plug-in; the 5.0mm interior and 7.4mm exterior diameters must match the laptop's DC jack exactly. The most frequent problem is ordering a tip size or voltage that does not correspond to the specific model, so verify the original adapter's specifications before purchasing.

Questions about this item

Does the 90 W adapter stay cool and quiet during all-day use?

The unit delivers 19 V at 4.74 A with no moving parts, so it runs silently and generates only modest warmth under continuous load.

What must I already own for this charger to work with my laptop?

You need a compatible HP EliteBook, ProBook or Compaq model that accepts a 5.0 mm blue-tip barrel connector with 7.4 mm outer diameter.

Will this 90 W supply safely power an older 65 W HP notebook I still use?

Yes — the adapter provides up to 90 W at 19 V, and the laptop will draw only the 65 W it requires.
