Hi chavdar, the compatible models are listed in the description, I do not believe it will fit a t42

Hello Steve. You should be able to use the compatibility tool provided by amazon to get confirmation. Hope that helps some.

The best thing to do is confirm the compatibility on StarTech.com ... my experience has been if it says it will fit/work there; you're good to go. Still, Amazon usually has the lowest prices to buy.

I got this for my 4820tg- you may want this one. http://www.amazon.com/Laptop-Keyboard-Aspire-3830TG-4830TG/dp/B00GX2N5HO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1424319097&sr=1-1&keywords=4830t+keyboard

I would presume that it is...check your model number and see if it is compatible.

Yes it is compatable because I have the same model and mine works perfectly.

It works on my 55LN5700 which uses the same firmware so it should work fine on your 42". Be aware that the keys are labeled in Korean not English.

It's compatible with the i7-4790 using the latest bios. It is not compatible with the i7-4790k.

I don't know if it is compatible or not. I know mine quit working after about 3 months.

I don't know. There was a list of compatible models in the item description. My TV was one of them.

I'm not familiar with that model but if it has three wires that go to it, it should be compatable. The new units come with the wired connecter so match the colors of wire and your good to go.

It works for my 32ld350, which is a 2010 model and probably older than a 42ld550.

Hello AnjaliYes they are compatible as 42t4911 is 55+ 6 Cell and older version and discontinued by Lenovo and 0A36302 is 70+ 6 Cell and new version, When we are sold out sometimes on 70+ 6 cell we ship 70++ 9 cell Battery which is better than 6 Cell.Thank you Miyanji

It worked from my T410 to T440P, so I would think you would be ok going from T420 to T440

Sorry that I'm answering this day, only want to say that it works for the model you asked. I have a 4800 model and it works perfectly, I recommend it.

yes, I use it with a 4430 but as long as it's lga 1150 you should be fine and its on the supported list.

I looked it up on Amazon....under specs for the 231 it does not list the 4000 series as compatible. Can always give it a try and return it if it doesn't work.
