170W AC Adapter for ThinkPad P50

This 170W AC adapter replaces the original Lenovo 90W, 135W and 170W chargers for the ThinkPad P50. It is intended for users who need a direct replacement power supply for that specific mobile workstation. The unit delivers 20V at 8.5A and includes a six-foot AC cord plus a six-foot DC cord for extended reach.

Installation notes and common issues

Connection is straightforward: plug the AC cord into a wall outlet and the DC connector into the laptop. The adapter accepts 100–240V input at 50–60Hz, so it works worldwide without a voltage converter. A frequent mistake is ordering this model for a system that requires a 230W, 300W or 330W charger; this unit will not meet the higher power demand.

Compatibility checks before ordering

Verify that your ThinkPad P50 originally shipped with a 90W, 135W or 170W adapter and not a 230W or larger unit. Confirm the Lenovo part number on your existing charger matches 4X20E50575, 4X20E50576, 4X20E50577 or 4X20E50578. Ensure the DC connector tip fits your laptop’s charging port before use.
