Well as the title says my Macbook Pro 15" A1286 will not turn on. This happened after my battery died. The strange thing is that the battery charges fine and the magsafe opreates perfect however the it will not turn on? I have done a SMC reset and PRAM reset. Does anyone know if the SMC QFN chip have failed?

-thanks
 
Thanks for all your help. I have tried all steps listed. It will work when I perform a SMC bypass however when I shut it down and leave it would not turn on. This model has the 2.4Ghz dual nividia GPU chipset. The logic boards part number is 820-2330-a. I had measured the circled component and it measures 0 OHM. Would anyone have schematics of this logic board or can identify the circled component?

-Thanks

If you dont know what component that is you should not pop the hood...

do this:

1. take magsafe off
2. push power button for 10seconds
3. while you push the power button connect magsafe and push power button for another 10seconds.
4. release power button and after that just start your computer as normally one push on pwrbtn..

:D
 
I had perform a SMC bypass several of times however it has not turned on. I checked the logic board and can find anything suspect.
 
this may look like a stupid answer, but looking at the board does the RAM seated properly ? it could be faulty RAM or maybe you can try to disconnect the battery connector from the logicboard for about a minute and try to connect it.
 
The memory is fine and seated. The battery is removable and does not use the connector to the logic board
 
Magsafe.

UPDATE:

Well the system does power on once I perform a SMC bypass. Thanks FuLL for your help. The magsafe does turn green however when I insert the battery the green light does not change to amber and the system with shut down. Once I remove the battery the SMC bypass does work. Any thoughts?

Do you have 2 user IDs?, it's just that this post is an almost verbatim copy of one above.

One thing to bear in mind is that this Macbook (at least, - and maybe all of them) won't turn on without a battery installed. However, this isn't typically true of PC laptops.
