Questions about this item

How do I connect the 4.8 mm external diameter plug to my HP Dv2139tx laptop?

Align the 1.7 mm internal diameter centre pin with the laptop socket and push straight in until the 4.8 mm outer barrel seats fully; forcing it at an angle bends the pin.

Will the detachable AC power cord need replacement if the insulation cracks?

Yes, the included 100–240 V 50–60 Hz cord can be swapped for any standard IEC C7 lead rated for 65 W without opening the adapter.
