Q: My Macbook pro won't turn on

My Macbook pro won't turn on properly. When I press the power button it makes a sound like it starts and the applelogo appears. Then it starts to think and at the bottom it looks like its downloading something, but when its almost half done the computer switches off.. It does this when it's plugged in and when it's not. it doesn't matter.. Hope to find out what I can do!!

MacBook Pro (13-inch Early 2011)

    Try restarting your Mac in Safe mode:

    - 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 Disc 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


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