T420s
The T420s is the third model in the T4xxs series and succeeds the T410s. Case parts, accessories and docking stations are incompatible with the conventional T420. It was produced between February 2011 and February 2013.
My T420 is in very good condition, only the card reader is missing. It has the second most powerful CPU, and the RAM has been upgraded.
