Power adapter for Lenovo Legion and ThinkPad

This 230W AC adapter delivers 20V at 11.5A through a square yellow slim tip. It replaces original 135W and 170W units for Legion Y920 Y740 Y730 Y720 Y545 Y540 and ThinkPad P73 P72 P71 P70 P53 P52 models. Buyers whose laptop requires a different connector shape or voltage cannot use this unit.

Thermals noise and power draw

The adapter uses a smart chip and Load Break System technology with overheat and short-circuit protection. High-temperature resistant and flame-retardant materials keep operating temperatures low during typical office or travel workloads. No fan is present so acoustic output is negligible.

Behaviour under sustained load

Fast charging restores a depleted battery from 0 to 100 percent in 0.6 to 1.2 hours depending on capacity. The internal chip continuously monitors device temperature and battery status to optimise current delivery throughout the cycle. Output remains stable at the rated 230W without thermal throttling during extended sessions.

Questions about this item

How do I install the ADL230SLC3A charger and which step do people often miss?

Plug the AC cord into the brick, insert the square yellow slim tip firmly into the laptop port until it clicks, then connect to mains power; the step people miss is verifying the tip is fully seated before switching on.

What maintenance or replacement will this 230W adapter need later?

Inspect the cord and square yellow slim tip for wear every few months; replace the unit if the cable frays, the tip loosens, or the brick runs unusually hot during 20V 11.5A output.

What limit appears first when this charger runs at 230W continuously?

The overheat protection engages first; the smart chip and Load Break System throttle output if the brick temperature rises beyond safe levels during sustained 20V 11.5A delivery.
