Questions about this item

How do I connect the 4.5 mm blue tip connector to my HP EliteBook 840 G3?

Align the 4.5 mm outer diameter plug with the laptop’s DC jack and push straight in until the 3.0 mm inner pin seats fully; forcing it at an angle bends the centre pin.

What part of this 65 W adapter wears out first with daily use?

The DC cable near the blue tip connector frays from repeated bending, so replace the whole unit when insulation cracks appear.

At what load does the 19.5 V 3.33 A output hit its limit during continuous operation?

The adapter reaches its 65 W ceiling when the laptop draws the full 3.33 A, causing the brick to run warmest under sustained maximum charge.
