Common Reasons for a MacBook Not Turning On

Some MacBook users have reported their laptops won't turn on. That happens occasionally and is no cause for alarm. You can fix your MacBook in several ways, depending on why it won't turn on.

The most common reasons for a MacBook not turning on are:

  • Insufficient power - If your MacBook has a faulty battery or your power cable is damaged, you won't be able to turn it on.
  • Hardware issues - If your display, keyboard, RAM, PRAM, NVRAM, T2 chip, or other hardware is faulty, your MacBook won't power on.
  • Software problems - Temporary bugs, glitches, and other software hiccups can sometimes cause your MacBook not to power on. Thus, fixing them can be the solution.
  • Hard drive issues - If the disk with your macOS installation is corrupted or damaged, you won't be able to start your MacBook.
  • Faulty macOS - Viruses and corruption can cause operating system problems. If that happens, your MacBook won't start up.

Recover and Back Up Your Data First When Your MacBook Won't Turn On

Initiate Basic Checks for a MacBook Not Turning On

Now that you've recovered your data, you'll need to fix your MacBook that won't turn on. However, you can run several tests to check if your MacBook Pro or Air is physically damaged and ensure its components work fine.

Option 1: Check for Any Signs of Power

It's a simple step that many users overlook. Before writing off your MacBook, check for any signs of power. If your electricity is out or your outlet is faulty, your MacBook won't be able to charge and power on.

Option 2: Check if You Have a Faulty Battery

Another reason for your MacBook not turning on is a faulty battery. If your MacBook's battery is damaged, you won't be able to start it. Try replacing the old battery with a new one to test it. If your MacBook turns on, your old battery is the problem.

Option 3: Check the Power Input

Another thing you should check is the power input. If your power cable is faulty or damaged, it won't be able to charge your MacBook. Moreover, it won't be able to provide your MacBook with the necessary power if your charging port is damaged.

Option 4: Check if Your Keyboard Works

You might be unable to turn on your MacBook because your keyboard doesn't work. With a faulty keyboard, you can't use the Power button to turn on your MacBook. Thus, connect a portable or wireless keyboard to your MacBook and try turning it on.

Option 5: Check the Screen

Your MacBook might not turn on if its display is faulty. If your screen is damaged or not working, you can't turn on and use your MacBook. You can test that by turning on your MacBook. If you hear it starting up with a whirring sound, but the screen is still black, your MacBook is fine; your screen is the culprit.

MacBook Will Not Turn On - Top 11 Advanced Fixes

Once you've established the cause of your MacBook not turning on and checked all the physical components, you can start fixing it. We've prepared the top 11 fixes with step-by-step instructions to help you repair your MacBook Pro or MacBook Air and make it usable again. If you are using an iMac, refer to the guide for fixing an iMac that's not turning on.

Fix 1: Disconnect All Peripherals

If you have connected many external accessories to your MacBook, the SMC (System Management Controller) will take longer to power on or simply won't be able to do it. Thus, disconnect all peripherals and try turning it on again.

Since your MacBook will suffer from the excess current due to the peripherals, the SMC will prevent it from switching on as a safety measure. Disconnecting all accessories will allow your MacBook to turn on.

Fix 2: Use the Keyboard Sequence

If you notice that your MacBook screen isn't dead and turns on but gets stuck on the Black Screen of Death, it may appear as if it's not turning on. However, you can try fixing that by using the keyboard sequence.

If your MacBook is stuck on the Black Screen of Death, it can still perform actions and commands even if you can't see them. Follow these steps to fix your MacBook by using the keyboard sequence:

  1. Press the Power button.
  2. Press the S key to send your MacBook to sleep.
  3. Hold the Power button for four seconds to force a shutdown.
  4. Once it powers off, wait 16 seconds and turn your MacBook on again by pressing the Power button.

Fix 3: Reset the T2/SMC Chip

The SMC handles crucial components on your MacBook. If the SMC is having problems managing your display or other essential parts, your MacBook won't be able to turn on. Thus, resetting the SMC on your MacBook can resolve the problem.

However, if your MacBook has an M1 processor, it doesn't have the SMC, so you can't perform the reset on such laptops.

Follow these steps to reset the SMC on a MacBook with a T2 chip:

  1. Turn off your MacBook.
  2. Press and hold the Power button for ten seconds.
  3. Press the Power button again after a few seconds to turn on your MacBook.

Follow these steps to reset the SMC on a MacBook without a T2 chip:

  1. Turn off your MacBook.
  2. Unplug the power cable.
  3. Press and hold the Shift + Option + Control + Power keys for ten seconds.
    press shift, option, control, and power keys
  4. Plug in the power cable and turn on your MacBook.

Fix 4: Do a T2 Security Chip Firmware Restore

The T2 security chip is a multifunctional chip with an integrated SMC chip. If the T2 chip is faulty, it won't respond to the Power button, meaning you won't be able to turn on your MacBook. Fortunately, when you update your macOS, the installation comes with device firmware updates (DFU).

These updates allow firmware to update and operate smoothly. However, your T2 chip firmware can get corrupted if the update fails. Follow these steps to do a T2 security chip firmware restore:

  1. Get a working MacBook and visit the official Apple website to download the app Apple Configurator 2.
  2. Open the app on your working MacBook.
  3. Connect it to the MacBook that won't turn on using a USB-C cable and the Master port.
    connect macbooks with usb-c
  4. Press the Power button on the working MacBook, then press and hold Control + Options + Shift (without releasing the Power button) until you see the DFU text on the screen.
    press power, control, option, and shift keys
  5. Release the four keys at the same time. Your MacBook that won't turn on is in DFU mode now.
  6. The DFU device on your MacBook that won't turn on will appear on your working Mac, so select it and click Action.
  7. Choose Advanced from the drop-down list and click Revive Device.
    revive device in dfu
  8. That will download the correct firmware for your T2 security chip, so wait for the installation to complete. It will automatically turn on your MacBook.

Fix 5: Do a Hard Restart

If your MacBook won't turn on, you can't restart it as usual. However, you can do it forcibly. Regardless of the MacBook model, a hard restart includes the same steps.

Follow these prompts to perform a hard restart on your MacBook:

  1. Press and hold the Power button until your MacBook boots.
  2. Press the Control + Command + Power buttons to restart your MacBook forcibly.
    power command control keys to restart

Fix 6: Check if Your RAM Works

Your MacBook won't turn on if your RAM doesn't work. To check if your RAM works correctly, turn your MacBook on and listen for beeps:

  • Repeating beeps - faulty RAM;
  • One beep every five seconds - RAM not detected;
  • Three beeps every five seconds - RAM didn't pass a data integrity check.

If your RAM is faulty, you must replace it to fix the problem. If your laptop doesn't detect it, open your MacBook and readjust your RAM to install it correctly. If your RAM didn't pass the data integrity check, see if you've installed it properly or consider replacing it with a different brand.

Fix 7: Boot a MacBook Pro in Safe Mode

Software issues or corrupted disk files can prevent a MacBook from turning on. You can fix this problem by booting your Mac in Safe Mode. Depending on the model, you can boot a MacBook in Safe Mode in two ways.

Follow these steps to boot your Intel-based MacBook in Safe Mode:

  1. Turn off your MacBook.
  2. Leave it off for 20 seconds, then turn it back on.
  3. Press and hold Shift while it's turning on.
  4. Once the login window appears, log into your Mac.

Follow these steps to boot your MacBook with Apple silicon in Safe Mode:

  1. Turn off your MacBook.
  2. Press and hold the Power button until you see the Loading startup options.
  3. Select a volume, then press and hold the Shift key.
  4. Click Continue in Safe Mode.

Once you put your MacBook into Safe Mode, let it finish booting. That may take a few seconds or minutes. Afterward, restart your MacBook to exit Safe Mode. Then, power it on again by pressing the Power button.

Fix 8: Reset NVRAM and PRAM

NVRAM and PRAM are tiny bits of memory storing specific settings for your MacBook. However, they can sometimes store corrupted files. If that happens, it can lead to your MacBook's inability to start up or cause the MacBook screen to flicker. Thus, resetting PRAM or NVRAM can resolve the problem.

Follow these steps to reset your MacBook's PRAM or NVRAM:

  1. Turn off your MacBook.
  2. Restart it by pressing the Power button.
  3. While it's starting up, long-press Command . Option + . + ..
    hold keys to reset pram/nvram
  4. Keep holding these keys until your MacBook restarts, which will automatically reset your PRAM or NVRAM.

Fix 9: Run Disk Utility in Recovery Mode

Recovery Mode is a built-in recovery system Mac provides its users. Thus, you can boot your MacBook into Recovery Mode to fix the problem of its inability to boot. If your MacBook has issues turning on due to a faulty or corrupted hard drive, you can use Disk Utility in Recovery Mode to fix it.

Follow these steps to run Disk Utility in Recovery Mode:

  1. Press and hold the Power button for ten seconds.
  2. Once you release it, press it again with the Command and . keys.
    hold power, command, and r keys
  3. Hold the keys until the macOS Utilities window appears.
    open disk utility in recovery mode
  4. Select your startup disk in Disk Utility. It's usually Macintosh HD.
  5. Click First Aid > Run.
    run first aid on startup disk
  6. Once First Aid repairs your startup disk, restart your MacBook.

Preventing Future Issues With Your MacBook Not Turning On

You can't predict that your MacBook will have issues turning on, so you can't do much about preventing it. However, taking good care of your MacBook can make it last longer and avoid startup problems.

To prevent future issues with your MacBook, you can:

  • Disconnect accessories when turning on your MacBook;
  • Correctly install new RAM;
  • Regularly update macOS;
