90W AC Adapter for Lenovo IdeaPad and ThinkPad

This 90-watt AC adapter supplies 20 volts at 4.5 amps to compatible Lenovo IdeaPad Z710 and ThinkPad T440p models. It replaces original part numbers including 59400486, 59400487, 59400493 and the 20AN series. The unit accepts worldwide input from 100 to 240 volts at 50 to 60 hertz.

Six-foot power cord and safety protections

A 6-foot two-prong AC cord extends reach to distant outlets without an extension lead. Built-in overload, short-circuit, over-voltage, over-current and over-temperature protections guard the adapter and the connected laptop during normal operation. The durable case resists water and humidity ingress.

Steady 90-watt output under sustained load

The adapter maintains its full 90-watt rating continuously rather than only in short bursts, delivering either 19.5 volts at 4.62 amps, 19 volts at 4.74 amps or 20 volts at 4.5 amps as the laptop negotiates. High power efficiency keeps the brick running cool during extended charging sessions. It is not suited for devices requiring higher wattage or a different voltage profile.

Questions about this item

How do I connect the 6 ft 2-prong AC power cord to the adapter and the wall outlet?

Plug the 2-prong AC cord into the adapter's IEC inlet, then insert the plug into a 100–240 V 50/60 Hz wall socket; the step often missed is seating the cord fully into the inlet until it clicks.

Which parts of this 90 W adapter are most likely to need replacement after extended use?

The detachable 6 ft 2-prong AC cord and the DC output cable with its barrel connector see the most wear; the adapter body itself has no user-serviceable parts.

At what point does the adapter's over-temperature protection activate during sustained full-load operation?

The built-in over-temperature protection triggers automatically when internal temperatures exceed safe limits during continuous 90 W output, shutting down until the unit cools.
