65W AC Adapter for HP Dv2131 and Dv2132

This 65-watt AC adapter supplies 18.5 volts at 3.5 amps for compatible HP laptops. It replaces the original charger for Dv2131ea, Dv2131tx and Dv2132ea models. The connector features a 1.7 mm inner diameter and 4.8 mm outer diameter. An AC power cord is included in the package.

Thermals noise and power draw

The unit accepts a universal AC input range of 100 to 240 volts at 50 to 60 hertz for worldwide use. It delivers a steady 65-watt DC output during normal operation. No active cooling fan is present so the adapter runs silently. Heat dissipation is handled passively through the enclosure.

Questions about this item

How do I connect the 1.7 mm inner-diameter barrel plug to my HP Dv2131ea, and what step is often missed?

Align the 1.7 mm inner and 4.8 mm outer diameters with the laptop's DC jack, push straight in until it seats firmly, then plug the AC cord into a 100-240 V 50-60 Hz outlet; the step often missed is confirming the plug is fully seated before powering on.

Which parts of this 65 W 18.5 V 3.5 A adapter will need replacement over time?

The detachable AC power cord and the DC cable near the barrel plug endure the most flexing; replace either if insulation frays or the connector becomes loose, while the sealed brick itself has no user-serviceable components.
