Questions about this item

How do I connect the 170W adapter to my ThinkPad W520 and what step is often missed?

Plug the 10 ft AC cord into a 100-240VAC 50/60Hz mains socket, then insert the DC tip firmly into the W520 power jack; the step often missed is seating the connector fully so the over current, over voltage and short circuit protections engage correctly.

What part of this charger will need replacement first after extended use?

The 10 ft power cord and DC cable endure the most physical stress from bending and coiling, so the cable assembly is the component most likely to require replacement before the adapter body itself.

Which protection limit activates first when the adapter runs at full 170W load for long periods?

Overheating protection with the smart chip triggers first under sustained maximum output, shutting the unit down before over current or over voltage thresholds are reached.
