The WAWEIS AC/DC adapter is built as a direct replacement for the Lenovo ThinkPad T540 with i7-4900MQ processor. It delivers mains power through a 10 ft cord and includes over current, over voltage, short circuit and total power protection. The unit carries FCC, CE and RoHS certifications.

Suits owners needing a spare or replacement charger

This adapter suits users who need a new mains supply for the listed ThinkPad model. It is not for buyers who require a battery pack, a USB-C power source or a higher wattage unit for other laptop models.

World wide 100-240VAC 50/60Hz input voltage

The adapter accepts 100 to 240VAC at 50 or 60Hz, letting it operate on mains supplies worldwide without a separate voltage converter. This single input range decides whether the charger matches the local power grid.

Questions about this item

Will this adapter work with my original ThinkPad T540 power cord?

The adapter includes a 10 ft power cord and is 100% OEM compatible with the ThinkPad T540 and i7-4900MQ models, replacing the original charger directly.

How can I confirm the adapter is delivering power correctly after I plug it in?

The adapter features overload, over-voltage, short-circuit and overheating protection with a smart chip; the laptop charging indicator will show normal operation when connected.

Does the package contain only the adapter brick or also the mains lead?

The adapter comes with a total 10 ft long power cord included, so no separate mains cable purchase is required.
