The picture shows a schematic which is similar to Mac Book Pro's power input circuit. The series components L1, F1, T1, T2 have to draw the full power, so those are of interest for us. With an ohmmeter you can check these parts.
-
L1: Since I could not figure out the manufacturer of this common mode choke I recommend to use a new MagSafe PCB.
-
F1: According to the printing on this part it is very likely that this is a Littelfuse 0469006 6A fuse.
-
T1, T2: Both MOSFETs are HAT1128R type. Since this part is obsolete I took IRF9317PbF

The picture shows where the relevant parts are placed on the logic board. F1, T1 and T2 are marked green. L1 is mounted on the MagSafe PCB and so not seen on the picture.
-
After you have figured out which of these parts (L1, F1, T2, T2) are defective you can change them. I recommend to replace both MOSFETs if there is at least one damaged.
-
After replacing the defective parts you can check the functionality by connecting the battery and the power adapter to the logic board. If everything is fine the LED of the MagSafe connector will light up green and switch to orange if battery will be charged. Be very careful.

I don't know if any 80w MagSafe. It should be 85w for 15" and 60w for 13"...
Great post! Thank you!
I can’t find T1 and T2. My board is little different from the picture . Mine’s 2011 or 12 i7 processor. Please help!
Admirable ! and the pics can be enlarged a lot ! thank you!
