Doees anybody have the power adapter with this P/N: 42T4430? Is this an original accessory designed to work with the T420?


The model number of my laptop is 4180-KP1.  I am asking as  I couldn't find the adapter with the same P/N in the hardware maintenance manual of the T420. 


The 42T4430  is an original Lenovo  battery and yes, it is designed to work with the T420.


The 4180-KP1 is  an integrated graphics model. Usually, a 65 watt adapter comes with a machine with integrated graphics, but any 65-watt or larger will work.
