170 W AC adapter for ThinkPad W520 and W530

This 20 V 8.5 A power supply replaces part 45N0113 on Lenovo ThinkPad W520 and W530 mobile workstations. It accepts 100-240 V 50/60 Hz mains input and delivers 170 W through a bayonet connector with centre pin. A mains lead is included in the package.

Capacity and headroom

The adapter provides the full 170 W rated output for CPU and GPU loads typical of the W520 and W530 platforms. It will not support systems that require a higher wattage brick or a different voltage rail. Buyers needing more power for larger workstations should look elsewhere.

Bayonet connector with centre pin

The output uses a proprietary bayonet plug with a centre pin that mates only with compatible ThinkPad models. Verify the connector shape and the 20 V 8.5 A rating on the original unit before ordering.

Questions about this item

Will the 20V 8.5A 170W output match the power draw of my ThinkPad W520 or W530 without overloading the laptop's charging circuit?

Yes, the 20V 8.5A 170W rating matches the original 45N0113 specification for ThinkPad W520 and W530 models, so the laptop's charging circuit will regulate current normally.

How can I confirm the baioneta com agulha tip is seated correctly and the adapter is delivering 20V 8.5A after I plug it in?

The ThinkPad battery icon will show "Plugged in, charging" and the LED on the connector tip lights solid; if the tip is loose the icon will flicker between battery and AC power.

Does the package include the AC power cord for the 100-240V 50/60Hz input side, or must I supply my own?

A free power cord is included in the box for the 100-240V 50/60Hz input, so no separate cable purchase is needed.
