90W AC Adapter for HP ProBook

This 90-watt AC adapter supplies 19.5 volts at 4.62 amps through a 7.4 by 5.0 mm barrel connector. It is built for HP ProBook 4510s, 4515s, 4525s, 4540s and 455 G1 notebooks. The unit accepts 100 to 240 volt input at 50 to 60 hertz and includes a US three-prong power cord.

Sustained-load behaviour

Over-current, over-voltage, short-circuit and total-power protection circuits guard the adapter during continuous operation. The supply is tested before delivery and carries a twelve-month warranty. It delivers its rated output steadily without thermal throttling under normal indoor conditions.

Installation notes

Plug the barrel tip into the laptop DC jack and the three-prong cord into a grounded outlet. The connector size must match the laptop exactly; a loose or reversed fit will prevent charging. No drivers or configuration are required. Buyers who need a different tip diameter or a higher wattage unit cannot use this adapter.

Questions about this item

Does the 90 W adapter run hot or make noise during all-day use?

The unit has over-current, over-voltage and short-circuit protection and is 100 % tested before delivery, which helps keep heat and noise low during continuous operation.

What must I already have for this charger to work with my ProBook?

Your laptop needs a 7.4 mm × 5.0 mm DC jack and a standard three-prong AC outlet; the package includes a US power cord.

Will this 19.5 V 4.62 A supply safely power my older ProBook 4510s or 4525s?

Yes — the adapter matches the original 19.5 V 4.62 A 90 W specification for the 4510s, 4515s, 4525s, 4540s and 455 G1 models.
