What this charger replaces

A DELL-branded 65 W AC adapter built to power HP ProBook and EliteBook models that use the 4.5 × 3.0 mm blue-tip connector. It suits owners of listed ProBook 430, 440, 450, 470, 640, 650 and EliteBook 725, 745, 755, 820, 840, 850, Folio 1020, 1030, 1040 series who need a direct replacement for a lost or damaged original unit. The adapter accepts 100–240 V input at 50–60 Hz for worldwide use. It is not for laptops that require a different tip size or a higher wattage brick.

65 W output and 45 W fallback

The brick delivers 19.5 V at 3.33 A for a full 65 W, and it also supports devices that draw 19.5 V at 2.31 A (45 W). This headroom covers most mainstream ProBook and EliteBook workloads including office applications, web browsing and video playback. It will not sustain charging on models that demand more than 65 W under load, and it cannot power USB-C only laptops that lack the blue-tip barrel jack.

Blue-tip barrel limits

The 4.5 mm outer by 3.0 mm inner diameter connector is a proprietary barrel standard used on the listed HP families. It carries no data lines and cannot negotiate higher voltages or alternate modes. Polarity is fixed, so the adapter will not work with centre-negative sockets or with slim-tip, USB-C or coaxial connectors found on other brands or newer HP ultraportables.

Questions about this item

Will this 65 W blue-tip charger work on my older HP ProBook 450 G3 that currently uses a 45 W adapter?

Yes. The adapter delivers 19.5 V at 3.33 A for 65 W and is also compatible with 19.5 V 2.31 A 45 W models, so it will safely power your ProBook 450 G3.

How can I confirm the charger is operating correctly once I plug it in?

The blue-tip connector fits the 4.5 mm x 3.0 mm port on supported ProBook and EliteBook models; when connected the laptop should show charging and the adapter’s short-circuit protection will prevent over-current.

What comes in the box and do I need a separate mains lead?

The package includes the DELL-branded 65 W AC adapter with a fixed blue-tip DC cable; the AC input accepts 100-240 V 50-60 Hz via a standard two-pin plug, so no extra cable is required.
