Targeted Replacement

This 65W AC adapter is built for Lenovo IdeaPad S540-15IML and S540-15IWL models, matching part numbers such as 81NG, 81NE, GX20L29355, GX20M73648 and SA10M42725. It delivers 20V at 3.25A to power the laptop and charge the battery whether the system is on or off. Buyers who need a 90W unit or a different connector will not be served by this adapter.

Power Step Up

The unit replaces original Lenovo 45W and 65W chargers, so users moving from a 45W brick gain extra headroom for sustained loads and faster battery replenishment. Worldwide input of 100 to 240V at 50 to 60Hz means the same adapter works at home or abroad without a voltage converter. It does not replace a 90W adapter, so machines that require that rating must look elsewhere.

Build Integration

A 6 ft 2-prong AC cord and a 6 ft DC cord combine for extended reach, removing the need for extension leads in most desk or travel setups. The ruggedised case measures 4.25 by 1.89 by 1.18 inches and weighs 10.8 oz, fitting easily into a laptop bag. Internal surge filtering and output limiting protect the notebook from line spikes and over-current events.

Questions about this item

What are the dimensions of the adapter body?

The adapter body measures 4.25 inches by 1.89 inches by 1.18 inches.

How do I connect the adapter and what is a common mistake?

Plug the AC cord into a wall outlet and the DC connector into the laptop; a common mistake is using this 65W unit on a model that requires a 90W adapter.

What parts may need replacement over time?

The 6 ft AC cord and 6 ft DC cord can wear from bending; the adapter itself carries a 1 year warranty.
