19 V 4.74 A 90 W replacement adapter

This 90 W AC adapter supplies 19 V at 4.74 A for the Lenovo 3000 G430 series and other listed models. It accepts 100-240 V input at 50-60 Hz so it works worldwide. The barrel connector measures 5.5 mm by 2.5 mm and a power LED shows when the unit is live. It replaces a long list of Lenovo part numbers including ADP-90RH B and 41R4322.

Steady 90 W delivery under load

The unit maintains its rated 90 W output continuously while the laptop draws full power for charging and operation. Input current adjusts automatically across the 100-240 V range without manual switching. No protective shutdown or throttling is described in the specifications. The adapter is designed to sustain the rated current for the duration of a typical charge cycle.

Passive cooling with status LED

The brick relies on natural convection and runs silently because no fan is fitted. A built-in LED indicator lets you confirm power presence at a glance. The package includes a detachable mains cord with a choice of US, UK, EU or Australian plugs and either a two- or three-prong outlet configuration. A 12-month warranty covers the adapter.

Questions about this item

Does the 90W adapter run hot or make noise when powering a Lenovo 3000 G430 all day?

The adapter delivers 19V at 4.74A for 90W output with a built-in power LED indicator; it has no fan, so it operates silently and warmth depends on load and ventilation.

What must I already own to use this 5.5 mm × 2.5 mm connector on my Lenovo 3000 G430?

You need the laptop itself with a matching 5.5 mm × 2.5 mm DC-in jack and a standard IEC C5 or C7 mains cord for the 3-prong or 2-prong inlet.

Will this 90W brick work alongside the original 65W ADP-65CH A supply I still have for the same Lenovo 3000 series?

Yes — both share the 19V output and 5.5 mm × 2.5 mm plug, so either can power compatible Lenovo 3000 models; the 90W unit simply provides more headroom.
