SUNMALLKeyboard Replacement Compatible with Lenovo ThinkPad T431 T431S E431 T440 T440P T440S E440 L440 T450 T450S T460 Series Laptop with Backlit and Point US Black Layout

A bit tricky to install. Make sure to check that not bent and has all sticky strips correctly fitted before attempting to install. My guy is a very experienced IT guy and struggled with the first one we received because it was bent slightly. We returned and received a new one and it installed much quicker. The box it comes in is not very protective for what is inside.

This was an exact fit and worked flawlessly as an upgrade from a non-backlit keyboard on my ThinkPad t440p. It is the LiteOn model, and the key strokes are exactly as you would expect for a ThinkPad. This was a great upgrade for my 2013-2014 era ThinkPad. I highly recommend this product from SUNMALL.

The media could not be loaded. I've purchased 2 of these and both had bad trackpoints. They work okay at first then start sending incorrect position and mouse clicks. I'm an experienced tech and made sure the connectors were clean and seated properly. The original keyboard's trackpoint works fine. I swaped keyboards with a Lenovo OEM and it works fine as well, so the problem is definitely in this replacement KB.

No se siente igual al original, but is okay

This is stright to the point pros and cons.Pros: looks new and functions when properlyInstalled.Cons: keys are noisy, uneven meaning not all are flat and loud clicks from all keys. I also realized this KB was hard to install and was really tight to where the cover between the keys are stuck forward not allowing access to the small screws. This means it would brake it if ever needed to replace again.I'm currently afraid of removing it if I wanted to return it which would be impossible.
