What this adapter replaces

This 65 W AC adapter replaces a lost or damaged original charger for the HP 2000-2C29WM and 2000-2B19WM. It matches the 18.5 V 3.5 A output and the 7.4 mm/5.0 mm smart-pin connector required by those models. The jump is worth it when the old unit no longer holds a stable charge or the tip is worn. A 2.5 ft US power cord is included in the box.

Connector fit and voltage match

The barrel tip measures 7.4 mm outer diameter and 5.0 mm inner diameter with a central smart-pin inside. That exact geometry lets the laptop recognise the adapter and enable full charging speed. Input accepts 100-240 V at 50-60 Hz so it works on mains worldwide without a voltage converter. Polarity and pin layout follow the OEM specification for the listed part numbers.

Sustained output behaviour

Rated at 65 W continuous DC output the brick delivers 18.5 V at 3.5 A under steady load. The three-prong inlet grounds the unit during extended sessions. No fan is present so cooling relies on the case surface area. It is not for buyers who need a higher wattage supply or a different tip size for other laptop families.

Questions about this item

Does the 7.4mm/5.0mm smart-pin connector fit my HP 2000-2C29WM?

Yes, the adapter uses a 7.4mm/5.0mm tip with a central smart-pin designed for the HP 2000-2C29WM and 2000-2B19WM models.

How do I install the adapter, and what step is often missed?

Plug the 3-prong US power cord into the adapter, connect the smart-pin tip to the laptop, then plug the cord into a 100-240V 50-60Hz outlet; the step often missed is ensuring the smart-pin seats fully so the laptop recognises the 65W supply.

When will the 2.5ft power cord need replacing?

Replace the cord if the insulation cracks, the plug prongs bend, or the connection becomes intermittent; the adapter itself has no user-serviceable parts.
