170W Adapter for ThinkPad W520 and W530

This 170W AC/DC adapter replaces the original power supply for Lenovo ThinkPad W520 and W530 laptops. It accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz. The unit is built with new components and carries FCC, CE and RoHS certifications. It is intended for users who need a direct replacement charger for these specific models.

Fits W520 and W530 units with listed part numbers

The adapter matches part numbers including 42824UU, NY54MGE, 4282B47, 42844LG, 4284A43 and NY54KGE. A 10 ft power cord is included so the brick can reach distant wall outlets without an extension lead. No internal battery is present, so the laptop must remain plugged in for operation. Builders who need a second card or a different connector type cannot use this unit.

Safety protections and thermal management

Over-current, over-voltage, short-circuit and total-power protection circuits guard the laptop and the adapter itself. Over-charge, over-discharge and overheating safeguards are managed by a smart chip. Anti-interference isolation materials reduce electrical noise. The supply runs on standard mains power without requiring a special circuit or higher-wattage service.
