When your MacBook® won’t turn on, it can be incredibly frustrating—you can't do much of anything with your laptop. But don't worry, we have some simple tips that can help get your device powered up again.

At Asurion, when tech breaks, we fix it. Whether your MacBook keys aren’t working or your laptop needs a new battery, our experts have all your tech care needs covered. We'll walk you through what to do if your MacBook Air or MacBook Pro is not turning on so you can get back up and running fast.

Check your power source

First, make sure your laptop is getting the power it needs. If your MacBook won’t turn on, the problem could be as simple as a dead battery. Plug it in and give it some time to charge—at least half an hour—before trying to turn it on again. Not seeing an increase in your battery power after plugging it up? Check out our guide for what to do when your MacBook battery won't charge.

Test different power cables and adapters

Not all chargers are created equal. Sometimes, the culprit behind your MacBook not turning on or charging is a faulty charger or adapter. 

Start by examining the charger for visible damage, such as frayed cables or bent connectors. Then try swapping out the charger for one you’re positive works and is compatible with your MacBook model. Also, check that the power outlet you’re connecting to is functioning—plug in other devices to be sure.

Check the screen

Press the increase brightness key on your keyboard or press and hold the sun icon in the Control Strip and move your finger to the right to make sure the brightness is turned up. If you accidentally set the slider all the way to the left, the screen will appear black, and your MacBook will look like it's turned off.

An unresponsive or black screen can also give the illusion that your MacBook isn’t turning on. Read our guide on what to do if your MacBook screen is frozen for more helpful details.

Disconnect any external accessories or devices

External devices can sometimes cause conflicts during startup and cause your MacBook Pro to not turn on. Unplug all accessories you have connected to your laptop—like printers, headphones, flash drives, HDMI cords, monitors, speakers, etc. Then start your MacBook again and see if that resolves the issue.

Perform a power cycle

If your MacBook still isn't turning on, you could run a power cycle to try to force it to restart. Try this:

1. Plug your MacBook into its charger and hold down the Power button for at least 10 seconds. This will cut all power to the MacBook, as if you removed the battery.
2. Release the Power button, leave it off for a few seconds, then press it again to start your MacBook.

Reset the SMC

The SMC (System Management Controller) plays a big role in your MacBook’s power function. Resetting it can potentially help. How you reset it depends on which processor your MacBook has. To check, go to the Apple menu > About This Mac.

For MacBooks with Apple silicon (M1, M2, M3, M4 chips and newer) These Macs do not have a manual SMC reset. Instead, the hardware management system resets itself every time you restart.

1. Shut down your MacBook completely.
2. Wait for 30 seconds.
3. Press the Power button (Touch ID) to turn it back on.

For Intel MacBooks (2018–2020) with T2 Chip

1. Shut down your Mac.
2. On the built-in keyboard, press and hold the following keys for 7 seconds: Control (left side), Option (left side), and Shift (right side).
3. While still holding those three keys, press and hold the Power button.
4. Keep holding all four keys for another 7 seconds, then release them.
5. Wait a few seconds, then press the Power button to turn it on.

For older Intel MacBooks (Pre-2018)

1. Shut down your Mac.
2. On the left side of the keyboard, press and hold Shift, Control, and Option.
3. While holding those three keys, press and hold the Power button.
4. Keep holding all four keys for 10 seconds, then release them.
5. Press the Power button to turn on your Mac.

Reset the T2 chip

If you have an Intel-based MacBook Pro or Air (2018–2020) equipped with the Apple T2 Security Chip, you can perform a quick reset of the power controller.

1. If the Mac is on, shut it down.
2. Press and hold the Power button (Touch ID) for 10 seconds.
3. Release the button and wait a few more seconds.
4. Press the Power button again to turn your MacBook back on.
