No Charge - Dim green light - MacBook Pro 13" Unibody Early 2011

Hi iFIXit Community :)

Let’s begin :

• MacBook Pro 13" Unibody Early 2011
• Boot OK when the battery is full
• No charge with MagSage plug in (dim green light…)

As I understand, it’s a mother board problem of charging system…

But Could someone help me to fix it myself ?

MotherBoard : 820-2936-B

• F7040 : no tension 0,1 V PPBUS_G3H (instead of 12,60 V)
• pp3v42 tension : OK
• u7000 acin tension : 0.25 V
• resistance between pin 17/18 : 94 ohms (C7050)
• resistance between 27/28 : 20 ohms (C7020)
