I took to an Apple Certified Technician and he suggested a change of HD, so I accepted, the battery is still good.

I got the MacBook back from the ACT for the issue I describe below.

 

It is a MacBook Pro the model before the Retina, it suddenly turns itself off, and it is hard to turn it on again, I have to wait about 10 minutes to press the Power botton to respond and when it is starting to turn on, I get what you see in the attached photo, sometimes the bar never gets to fill up and the machine turns it self off.

I am sorry the image came upside down.

Can someone please tell me what I can do?

    It's failing one of the self-tests that run in safe mode. Usually that means the boot drive is bad, but it could be some other hardware fault. You could try running the Apple Hardware Test, but it's not very reliable.

    Linc:

    The MacBook Pro has been at the Apple authorized Repair center, they run tests with some Diagnosis CDs they use, and they decided that it was the HD, so I authorize them to replace it, when I got back the mac, it worked fine a few hours

    then again began to turn itself off connected to the wall outlet or running in battery.

    I took it back to the Apple Repair and after a few days I was told that it never turned itself off but anyway they took it all apart and cleaned all the electric terminals.

    The MacBook some times does not turn itself off always

    Back up all data to at least two different storage devices.

     

    Boot into Recovery, launch Disk Utility, and erase the startup volume. This operation will destroy all data on the volume, so you had be better be sure of your backups. Quit Disk Utility and install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

     

    When you reboot, you'll be prompted to go through the initial setup process. That’s when you transfer the data from one of your backups. For a walkthrough, see here:

     

    Using Setup Assistant

     

    Don't transfer the Guest account, if it was enabled on the old system.

     

    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

    Although it sounds very complicated for me to perform, I will give it a try

    Thank you very much

    I don't actually expect that procedure to do any good, but you have to do it anyway to rule out anything other than a hardware fault. I think you do have a hardware fault.

    I totally agree with you that I have a hardware fault.

    Thanks
