230W AC Adapter with Yellow Tip

This 230W AC adapter delivers 20V at 11.5A through a yellow USB tip connector. It is built as a direct replacement for the original Lenovo power supply used by Legion and ThinkPad mobile workstations. The unit accepts a universal 100-240V input for worldwide use. Buyers needing a spare or replacement charger for supported models will find the correct voltage and tip style here.

Verify tip style and part number before ordering

Confirm that your laptop uses the yellow USB tip and requires 20V 11.5A output. Cross-reference your original adapter part number against the listed compatible PNs such as ADL230NLC3A, PA-1231-12LA or 4X20E75115. The adapter is not suitable for devices that use a different tip geometry, a lower wattage rating or a proprietary slim-tip connector. Using an incorrect tip can prevent charging or damage the port.

Steady 230W output under continuous load

The power supply maintains its rated 230W output during extended gaming or workstation sessions without throttling. Internal protection circuits guard against over-voltage, over-current and short-circuit conditions while the unit runs at full capacity. Thermal management keeps the brick within safe operating temperatures during multi-hour workloads. It is not designed for devices that demand more than 230W or for simultaneous charging of multiple high-power peripherals.

Questions about this item

Does the charger come with a mains power cord or do I need to buy one separately?

The adapter ships with a yellow USB tip connector for the laptop; a separate mains cord is not included.

How do I decide between the 230 W and the 170 W versions listed in the part numbers?

Choose the 230 W unit (20 V, 11.5 A) when your Lenovo model requires the higher output; the 170 W variant delivers less power.

Will the 230 W rating actually deliver that power to my Legion Y740 under load?

Yes, the adapter supplies 20 V at 11.5 A, matching the 230 W input spec of the Y740 series.
