Q: MacBook Air screen went fuzzy and turned off. Can't turn it on now.

My MacBook Air screen went fuzzy (like a TV with bad reception), then black. When I try to turn the computer on, I just get a beeping sound (three beeps, pause, three beeps, pause). Screen stays black. What should I do?

    Hi.

    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!

    The three beeps indicate that there is a RAM problem with the MBA.  Since RAM is not user replaceable on a MBA, your best option is an appointment at an Apple store genius bar for a FREE evaluation.
