Replacement power adapter

This 65 watt AC adapter replaces the original charger for a wide range of Lenovo IdeaPad and Yoga laptops. It delivers 20 volts at 3.25 amps and also covers 45 watt models that use 20 volts at 2.25 amps. The unit accepts 100 to 240 volt mains input at 50 or 60 hertz for worldwide use.

4.0 by 1.7 mm barrel connector

The tip measures 4.0 millimetres outer diameter by 1.7 millimetres inner diameter, matching the charging port on the listed IdeaPad 1, 3 and 5 series as well as Flex, Yoga and Chromebook models. A secure fit prevents intermittent charging caused by loose or worn connectors. The cable length allows comfortable desk or bedside placement without strain on the port.

65 watt output decides compatibility

The adapter supplies up to 65 watts, so it powers any supported laptop that requires 65 watts or less at 20 volts. Machines needing a higher wattage or a different voltage will not charge correctly with this unit. Verify the original charger’s output rating and the 4.0 by 1.7 mm connector before purchase.

Questions about this item

What does the 20 V 3.25 A output cap in real use?

The adapter delivers up to 65 W at 20 V 3.25 A and also supports 45 W models that draw 20 V 2.25 A, so it covers both power levels without exceeding the laptop's own limit.

Will the 4.0 x 1.7 mm barrel plug fit my Yoga Chromebook charging port?

Yes, the connector measures 4.0 mm outer diameter by 1.7 mm inner diameter, which matches the port on the IdeaPad Yoga Chromebook listed in the compatibility data.

How do I install this charger and what step do people often miss?

Plug the barrel tip firmly into the laptop until it seats, then connect the AC cord to a 100–240 V outlet; the step users skip is verifying the tip orientation before forcing it, which can bend the centre pin.
