Lenovo Trim Yellow rectangular power adapter












0














Need Lenovo Yellow Power adapter connector information, its a MYSTERY to me!!
Options
‎



Hello all, I recently just purchased my first Lenovo products with the new Yellow rectangular power adapter.



I have the Lenovo M900 Tiny desktop and the Lenovo 23 inch 10dqd monitor. Each have the Lenovo rectangular Yellow Power conectors.
I I am trying to understand how these connectors can be installed in either direction and still have the correct polarity.



Here are information that I have researched so far on the internet regading these style connectors.




  1. The Lenovo power connectors are called "TRIM Series connecotrs some manufacturers label the connector C36.


  2. The connector interior has two copper plates on each small side of the rectangular connector and a CENTER pin that some manufacturers have labeld the DATA connetion.


  3. The Yellow connector at the end of the Power adapter is supplying 20VDC and the current rating of the adapter is proportional to the device it is connected . Ratings usually are in power 35W, 65W , and a 135Watt,



I hope someone can explain how the Power adapter connector can be inserted in either direction , and still supply the correct polarity to the Leveno product?



Thanks Rob

          Quick explanation



          This image seems to point to the internal plates being connected internally, with the outside as a 0v line



          link



          In depth explanation



          As the two plates are connected, which plate is on which side shouldn't matter, as they are directly connected to each other.



          This can best be explained with the following diagram:Lenovo diagram



          Black is 0v, red is 20v, blue is the data pin, if you flip the diagram 180 degrees it is the same:Lenovo diagram



          So no matter which way up the connector is, the inside plates are at 20v, the outside shell is at 0v, making the connector still work, so the laptop can take its power between either of the inside plates and the shell and always get 20v with the same polarity.



          Side note - Data pin



          The resistance between the data pin and ground indicates the power rating.

|65 W |280 Ω | 
          
|90 W |550 Ω |

          I'm sorry, I have no electrical background, and therefor I do not understand your answer. Could you edit it further to elaborate more? Explain in basic english why this works? Probably needs some explaination of the interior of the laptop too, not just the connector.
