170W AC/DC Adapter for ThinkPad W520

This 170W AC/DC adapter replaces the original charger for ThinkPad W520 models including 42763JU, 42763KU and 427639U. It supplies the exact voltage and current required by the laptop, so the system charges and runs without throttle. The unit is new and built to match OEM specifications.

World-wide 100-240V input with 10 ft cord

The adapter accepts 100-240VAC at 50/60Hz, making it suitable for office, home or international travel without a voltage converter. A total 10 ft power cord gives ample reach from wall outlet to desk. It handles the W520's full load but cannot power higher-wattage workstations that demand more than 170W.

Over-voltage, over-current

Built-in safety circuits provide over-voltage protection, over-current protection, total power protection and short-circuit protection. A smart chip adds overheating protection while anti-interference materials reduce electrical noise. The adapter runs quietly and meets FCC, CE and RoHS certification standards.

Questions about this item

Will this 170W adapter work with the original ThinkPad W520 power port?

Yes, it is 100% compatible with the W520 models 42763JU, 42763KU and 427639U and fits the original power port.

How can I confirm the adapter is delivering power correctly after I plug it in?

The smart chip provides overload, over-voltage, short-circuit and overheating protection; the laptop charging indicator will show normal charging when the unit is working as intended.

Does the package include both the mains cable and the DC cable, or must I buy a cord separately?

The adapter comes with a total 10 ft long power cord, so both the AC mains lead and the DC output lead are included — no extra cable is required.
