No, I am sorry but it does not work with the T420. The computers that it works with are listed in the bullet points.

Yes, it will. I checked with Lenovo compatibility matrix. Anything T440 and above (including "s" and "p" subseries) will do.

If it's a net10 card it should work. I used a net10 airtime card on my T401g before.

I have mine installed on a IBM T43 and it works fine. I would give it a try.

Yes it is compatible with the t440s. When ever buying computer product on amazon always be sure to receive and item that is in the original mfg packaging that is factory sealed by the manufacturer. If it is not in the original factory sealed mfg packaging with the lenovo name on the box label and security tape, buyer beware.

Sorry, I don't know. I have a Lenovo T430-S.The mini-dock works perfect;y with this computer. Your portable has to have the matching connector for the doc on the underside. Jeff

No, the T440S uses a different dock. According to Lenovo, the correct dock for the T440S is part number 40A10090US.

No, the keyboard style has changed from T420 to T430. The power button in T420 is in the middle compared with T430 in which the button is on the right corner. I own both T420 and T430. They keyboard style is just too different on these two models; therefore, same keyboard protector cannot work on both. Plus, I do not recommend getting a clear keyboard protector. I used to own one of these. Yes, they are soft and clear, but they get dirty (yellow-ish/brown-ish) after being used for a while. I purchased a black one and it has been much better.

Not sure. I purchased for a T61 and it works fine. I based my purchase on the compatibility with this laptop.

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

I had a Thinkpad T420 and it worked with that. If you want to be sure, go to the Lenmar website and ask. I asked them before I got my current laptop and they answered pretty quickly. As for how long it lasts? On the Thinkpad it would power it for about 2 hours.

It doesn't appear to fit the T40. The package states For RS 4, RS 5, RS 6, RS 8, RS 40, RS 400, RS 2400, IS380, IS 150, IS 300, Set 250, Set 500, Set 2500, A 200

I purchased this for a Lenovo x230t based on my research on the Lenovo parts/support website. I do not know about the t400. Good luck.

Yes. It will work with the t440 and t440s I know for sure. Also heard it works with the x240, but not sure on that one. I have the t440s and it is a great battery. It will lift the laptop slightly but the raised angle is still comfortable. I run the 3 cell until I need to switch over or if I know I am going to be unplugged all day I run the 6 cell. Will give you 11 hours run time depending on configuration.

Yes, it supports the T410. The unit also has a digital and composite video out allowing you to run two monitors -- I am doing it now.

I have the T300, but they may not be that different. If it's a 10 inch with a keyboard attachment, this will probably work for it.
