Replacement AC Adapter for IdeaPad S340 and S540

This 65 W AC adapter replaces the original Lenovo charger for IdeaPad S340-15IWL Touch and S540-14API models. It supplies 20 V at 3.25 A to power the laptop and charge the battery whether the system is on or off. The unit accepts worldwide input from 100 to 240 V at 50 to 60 Hz.

Thermals Noise and Power Draw

The adapter operates at up to 65 W output with high power efficiency for consistent delivery. Internal safety circuitry filters input voltage spikes and limits output voltage and current to protect the laptop from electrical hazards. A ruggedised case withstands harsh mobile environments and seals against moisture and high humidity.

Build Fit and Cable Reach

The package includes a 6 ft UL-listed 2-prong AC cord and a 6 ft DC cord for extended reach without extension leads. The brick measures 4.25 x 1.89 x 1.18 inches and weighs 10.8 oz. This adapter does not replace Lenovo 90 W units, so verify the original wattage before purchase.

Questions about this item

How do I connect the 6 ft AC cord and 6 ft DC cord to the adapter, and which step do people get wrong?

Plug the 2-prong AC cord into a 100-240V outlet first, then insert the DC barrel tip fully into the laptop; the common error is leaving the DC connector half-seated, which prevents the 20V 3.25A output from engaging

What part will need replacement first and when should I check it?

The DC cable near the barrel tip sees the most flexing; inspect it every few months for exposed conductors or intermittent charging, and replace the whole adapter if the cord sheath is damaged

What thermal or power limit appears first during continuous 65W load?

The ruggedised case relies on passive convection; sustained maximum output can raise the brick temperature until the internal over-temperature protection cycles the 20V output off until it cools
