Replacement charger for Lenovo round-tip laptops

This DELL ADP200325UZF unit supplies 20V at 3.25A for a maximum of 65W and also covers 45W models. It fits a long list of IdeaPad 3, Slim 1, Flex and Yoga 710 machines that use the 4.0mm by 1.7mm round connector.

Thermals noise and power draw

The adapter accepts 100–240V input and delivers up to 85W rated output while staying within UL safety limits. Retractable prongs reduce the risk of bent pins during transport, and the corded electric design keeps the brick cool under normal load.

What the bundle changes

Only one replacement charger is included; no extra cables, tips or software are supplied. Buyers who need a second unit for a desk and a bag, or who require a different tip size, must source those separately.

Questions about this item

How do I plug the 4.0mm x 1.7mm round tip into my Lenovo Ideapad 3 charging port without bending the pin?

Align the round tip straight with the port and push gently until it seats fully; the 20V 3.25A output requires a firm, straight insertion to avoid damaging the centre pin.

When should I replace the cable or the foldable prongs on this 65W adapter?

Replace the unit if the cord shows exposed wires near the connector or if the retractable prongs no longer lock in the open position, as either fault can interrupt the 100-240V input supply.

What is the first limit I will hit if I run this charger at 65W continuously?

The 20V 3.25A 65W output rating is the thermal ceiling; sustained maximum load will cause the adapter to reach its designed temperature limit before any other component does.
