Hi All, I'm currently trying to repair a 820-2879 Macbook Mother Board and here are the symptoms: No Magesafe's green light G3Hot (PP3V42_G3H) is shorted to ground After removing the Coil L6995 to figure out where is coming from the short, it comes after the Coil : C6999 is also shorted to ground but it is not responsible of that short. So another componant is putting this track to the ground. OK need to find out witch one it is......BUT beside that i've mesured the output of U6990 on pin 4 (P3V42G3H_SW ) without L6995, i should normaly read 3.42V but strangely i'm reading 15.2V???? Someone of you guys had this problem before? where this 15.2V voltage is coming from? is the U6990 dead?
