The connector that must match

The square yellow tip is the single specification that decides fit. Only laptops listed with that exact connector will work. Models using a different tip shape or voltage will not power on, even if the wattage matches.

Installation and common issues

Plug the AC cord into the brick, connect the tip to the laptop, then attach mains power. The unit accepts 100-240V 50-60Hz input worldwide. The most frequent problem is ordering the wrong tip; verify the square yellow connector against the original adapter before purchasing.

Questions about this item

How much power does the 135 W rating actually deliver to my laptop?

The adapter supplies up to 135 W at 20 V and 6.75 A, matching the original ADL135NLC3A and ADL135NDC3A units for compatible IdeaPad and ThinkPad models.

What does the square yellow tip connector limit in practice?

The proprietary square yellow tip fits only the listed IdeaPad Gaming, IdeaPad 5 Pro, Yoga Creator and ThinkPad P, T, X1 Extreme and Y series laptops; it will not connect to barrel or USB-C devices.

What physical clearance does the brick need on my desk or in my bag?

The compact brick plugs directly into a standard IEC C5 cloverleaf cable, so it only requires space for the brick itself and the square-tip cable run to the laptop.
