Replacement Power Supply for ThinkPad W510

This 170 W AC/DC adapter replaces the original charger for Lenovo ThinkPad W510 units carrying part numbers 4391WDP, 4389W2V, 43194MU, 4391N9U, 4389AG1 and 438922U. It accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz. The unit is built with new components and carries FCC, CE and RoHS certification.

10 ft Power Cord and Protection Features

A 10 ft mains cord is integrated, giving extra reach between the wall outlet and the laptop. Safety circuitry includes over-current protection, total power protection, over-voltage protection, short-circuit protection, over-charge and over-discharge safeguards, and overheating protection managed by a smart chip. Anti-interference isolation materials are used throughout.

170 W Output for High-Performance Mobile

The 170 W rating matches the factory specification for the ThinkPad W510, supplying full power for CPU-intensive workloads and discrete graphics while charging the battery. It will not support laptops that require a higher wattage adapter, and it cannot power devices that use a different connector or voltage profile.

Questions about this item

Will the 10 ft power cord or the adapter unit itself need replacing first after heavy daily use?

The 10 ft cord endures frequent bending and plug cycles, so it typically wears out before the sealed adapter housing with its internal protection circuits.

What thermal limit triggers protection first when the 170W adapter runs continuously at full load?

Overheating protection with the smart chip activates before overload or over-voltage circuits, shutting the unit down until it cools.

How much heat and fan noise does the 170W brick produce when charging a ThinkPad W510 all day?

The sealed brick has no fan, so it runs silent; surface temperature rises under sustained 170W load but stays within FCC, CE and RoHS safety limits.
