How to Fix It When MacBook Pro Won’t Turn On

Last Updated on by Daniel Lawrence

If your MacBook Pro won’t turn on, there are a few common causes that could be leading to the issue, including a faulty battery, damaged logic board, or a hardware issue. If your MacBook Pro is under warranty, take it to an authorized service center to get it repaired. If it’s not under warranty, however, it’s time to use one of the methods below to get it back up and running again.

What to Do If Your MacBook Pro Won’t Turn On

Listen for sounds from the fan or humming or whirring noises after pressing the Power button on the MacBook Pro. Your Mac is starting up fine if you hear anything or see lights on the keyboard, but your display has an issue that may require professional assistance. If you don’t hear or see anything, these repairs may be able to get your MacBook Pro up and running again.

How to Fix It When MacBook Pro Won't Turn On

  • Examine the electrical connections: The first thing to check if your MacBook Pro won’t switch on at all is whether it’s plugged in. Wait a few minutes before restarting your Mac. Remember to test the power outlet with a lamp or another device to ensure that it works properly.
  • Replace the power cord or adapter: The power cord may be faulty if the Mac is plugged in but does not turn on. Replace it with a known-good cable to help narrow down the problem.
  • Battery should be charged:  The battery on your laptop may be dead if you use it on battery power. Before turning on the MacBook on battery power, plug it in and wait at least 10 minutes for the battery to charge. If you can’t charge the battery, take it to an Apple Authorized Service Provider or an App Store for a replacement.
  • Increase the brightness of the screen: It’s possible that the MacBook Pro is turned on but hidden from view. To brighten the screen, use the F2 key at the top of the keyboard. The brightness control on MacBook Pros with the Touch Bar is on the Touch Bar, and if the Touch Bar isn’t lighted up, the MacBook Pro isn’t turned on.
  • Remove all of Mac’s attachments and peripherals: A printer, external drive, USB hub, or mobile device—or one of the cables—could cause the Mac to not start.
  • System Management Controller has to be reset (SMC): Much of Mac’s basic functionality is controlled by the SMC, from the display and lights to the fan and Power button. It’s possible that resetting it will fix whatever is preventing the MacBook Pro from turning on. For MacBook Pros from 2009 or older, as well as current MacBook Pros with the T2 security chip, the approach is different.
