Replacement Adapter for ThinkPad W540

This 135 W AC adapter replaces the original Lenovo ADL135NDC3A and 45N0362 units for the ThinkPad W540 with i7-4900MQ. It accepts worldwide input from 100 to 240 VAC at 50 or 60 Hz and ships with a 10 ft power cord. The unit is brand new and carries FCC, CE and RoHS certifications.

Plug-in Installation with Built-in Safeguards

Installation is a direct plug-in: connect the barrel tip to the laptop and the IEC cord to a mains socket. The adapter includes over-current, over-voltage, short-circuit and total-power protection plus a smart chip for overheating guard. A 12 month warranty covers defects, but the package contains no mounting hardware or extra cables.

Stable Output During Extended Use

Under sustained load the protection circuits maintain regulated output without tripping, while the smart chip manages thermal rise during long charging sessions. The 10 ft cord allows flexible desk routing so the brick stays ventilated. Buyers needing a higher-wattage brick for other models or a USB-C power delivery option cannot use this unit.
