Q: Macbook doesn't start anymore

Hello,

 

i have a problem with a MacBook A1342. This Macbook doesn't start anymore.

 

I press the Power Button and nothing happens.

 

I tried to power it on with another MagSafe but this still doesn't work.

 

Also the MagSafe doesn't show any LED ligh at all.

 

I have also changed the Logic Board. But there is the same issue with the other one.

 

What could be the problem of this failure? And how can i fix this?

 

Thank you very much.

 

Philipp

MacBook, OS X El Capitan (10.11.3)

    Take a look at the steps suggested by Apple in this article:

    If your Mac won't turn on - Apple Support


    Try Safe Boot:


    - Shut down your Mac

    - Wait until your computer turns off and after that press the Power button

    - Right after you hear the startup tone, press and hold the Shift key

    - Release the Shift key when you see a grey Apple sign and the progress bar below this sign

    - After your Mac boots up, restart it as you usually do.


    If this doesn't help, follow the instructions below:


    - Shut down your Mac

    - Wait until your computer turns off and after that press the Power button

    - Right after you hear the startup tone, press and hold the Shift key

    - Release the Shift key when you see a grey Apple sign and the progress bar below this sign

    - Once you see Desktop, start a Disk Utility scan to detect and repair file system errors (don't forget to choose your main hard drive)

    - Click on Verify Disk and then, if asked to fix problems, on Repair Disk

    - After this, click on Verify Disk Permissions and then on Repair Disk Permissions

    - After the process is finished, shut down your Mac and turn it back on after about 30 seconds


    Apart from that, take a look at this Apple article and follow the instructions on Resetting NVRAM shown there: How to Reset NVRAM on your Mac - Apple Support


    Try resetting the System Management Controller: https://support.apple.com/en-us/HT201295


    Hope this helps!

    Thank you for your quick reply.

     

    I tried all the above shown steps to start the Macbook. But nothing helps for my issue.

     

    Could it be possible that the DC board of the Macbook is broken?

     

    Thank you for your help

    Yes, that is a possibility.  The question is how can you test for it since the Mac is not functional.  Try to get an appointment at an Apple store genius bar and perhaps they can assist in your trouble shooting.

     

    Ciao.

    Thank you very much.

     

    I will try this.

     

    How can i test by myself if the DC board is working or not?

    If the MBP were functioning, you could run an Apple Hardware Test, but since it is not functioning, that is not an option, hence the genius bar recommendation.  There is nothing else that I can think of to suggest.
