Questions about this item

How do I connect this 18.5V 3.5A adapter to my HP ZT3250 and what is the common mistake?

Plug the AC cord into a 100-240V 50-60Hz outlet then insert the DC tip with 1.7mm inner and 4.8mm outer diameter. The step people get wrong is forcing the connector without aligning the centre pin, which bends the socket.

Which parts of this 65W charger will need replacement over time?

The AC power cord and the DC cable near the strain reliefs wear first. The internal capacitors also age after several years of daily use. Replace the whole unit if output drops below 18.5V 3.5A.
