I Can’t Turn My Macbook Pro On
Check To See If The Macbook Is Powered Off Or Just The Screen:
Does the Caps Lock key still light up? Does pushing the power button make a chiming noise? Does the keyboard feel slightly warm? If “yes” to the above, then the issue is probably with the screen. Move on to the next problem on our list.
Check For Power Issues:
If it’s truly off and refuses to turn on, cover the basics first. Is the battery charged? Does your Laptop work with the power cord plugged in? Does a different power cord work? This indicates a problem with the battery or power cord. Try disconnecting everything (mouse, mobile devices, etc.) to see if that helps fix the problem.
Hard Restart Your Macbook:
Hold down the Power button for at least 10 seconds. Push the Power button again to see if the Mac turns on.
Remove Any Manual Upgrade(S):
Sometimes, an upgrade like new memory can freeze a laptop in permanent “uh-oh” mode. This is rare for the Air, which is compact and not upgrade-friendly. However, if you have added memory or other capabilities via external or internal work, removing upgrades may solve the problem.
