ThinkPad T420 original power adapter P/N

Dear owners of TP T420,

 

I have a question, does anybody have the power adapter with this P/N: 42T4430?

Is it original one and designed to work with T420 or is it mistakenly included with my T420 model?

 

Here is the model number of the laptop: 4180-KP1

 

Thank you in advance.

Hi,

 

That power brick - 42T4430 -  is the same one that came with my T420 purchased last month.

 

What is your concern?

You have an integrated graphics model. Usually, a 65 watt adapter comes with a machine with integrated graphics, but any 65-watt or larger will work.

Hello,

 

 

Many thanks for the info. The reason I'm asking is that I couldn't find the adapter with the same P/N in the HW Maint. Manual of T420. Take a look at page 164 http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0a60007_04.pdf

 

I purchased the T420  laptop which is on the road now, just had some doubts if the adapter is original or not.

 

 

Thanks again.
