Re: Apple 85W MagSafe Power Adapter - blown - help with components

Hi momaka!

Yes, of course! The top side had a lot of "silicone" in there and it was really time consuming to put it all out. You have to go slowly and carefully to not damage any of the components.

P.S.: someone knows if this "silicone" is there just to "hold" the components or is it something more "special" and maybe has increased thermal conductivity to spread the heat around more evenly??...

Re: Apple 85W MagSafe Power Adapter - blown - help with components

Hi guys, thank you for the replies!



Thanks "PeteS in CA" for a thorough explanation. I was sure there must be something else wrong that blew the IC and the resistors... I will also check the MOSFET. I am also a little worried about the "vaporized traces", hopefully I will be able to fix them. Any idea on the resistors values?



Thanks "ACS-Repair"! I know that, and that's why (if I manage to fix it) I will only use it as a "backup"...

Maybe instead of the DAP013F it is the DAP015D?

Re: Apple 85W MagSafe Power Adapter - blown - help with components

Hi techtiger,

thanks for the schematic. As I can see the IC34 is not the same? It has 14 pins, the chip on my board has 16 pins...

Hi, I have an 85W MagSafe Power Adapter, Model No: A1343, worked ok,
then suddenly dead. Opened it up and there are a few components blown.
Two resistors and a chip.

You can see more on the attached pictures.

Unfortunately I can only read the few last characters on the chip - an N on the top and 3261 or 5261 on the bottom (can't rally tell, the character is halfway visible but most probably is a 5261). The chip is blown right on the position where the model/type is printed. The resistors are also hard to tell.

Can anyone of you experts...
