170W AC/DC adapter for ThinkPad

This 170-watt power supply replaces Lenovo part numbers 0A36229, 42T5180, 42T5029, 42T5020, 42T5014, 42T5099, 42T5062 and 42T5147. It accepts a worldwide 100 to 240 volt input at 50 or 60 hertz. The unit is built for owners of compatible ThinkPad models who need a direct replacement charger.

Ten-foot cord and protection features

A ten-foot power cord is included, giving extra reach between the wall outlet and the laptop. Safety circuitry provides over-current, over-voltage, short-circuit and total-power protection. The adapter carries FCC, CE and RoHS certifications and uses a smart chip for overheating protection.

Check connector and wattage match

Verify that your ThinkPad uses one of the listed part numbers and requires a 170-watt input before ordering. This adapter is not for devices needing a different wattage, a different connector style or a USB-C power delivery profile. Buyers who need a higher-output supply or a slimmer travel unit should look elsewhere.

Questions about this item

Will the 10 ft power cord need replacing before the adapter itself?

The 10 ft cord is a single integrated assembly with the adapter; if it frays or the connector loosens the whole unit is replaced rather than the cord alone.

What thermal limit appears first when the 170 W unit runs continuously at full load?

The built-in overheating protection with smart chip shuts the adapter down before internal components exceed safe temperature.

How much heat and fan noise does the 170 W brick produce during all-day operation?

The adapter has no fan; it relies on passive cooling and the smart-chip overheating protection, so it runs silently while warm to the touch.
