MacBook Won't Turn On? Quick Checks

Is it really off?

Start by deciding whether your MacBook is completely dead or only showing a black screen. Those are different problems with different fixes. Press the power button, then look and listen for signs of life:

• A startup sound, on models that have one
• Fan noise or a faint hum
• The keyboard backlight turning on
• The Caps Lock key light responding when you press it
• A light on the charger connector (on MagSafe models)

Any of those means power is getting through and the problem may be the display. No signs at all points to power, the battery or the logic board.

Step 1: Rule out the charger and outlet

Most "dead" MacBooks turn out to be a power issue. Check:

• The outlet. Plug a lamp into it, or try a different outlet. Skip power bars with a switch that may be off.
• The cable and adapter. Look for fraying, kinks or a bent connector. Try another cable and adapter if you have one.
• The port. On USB-C models, try a different port. Look inside for lint or debris with a flashlight.
• The MagSafe light. On MagSafe 3 models, the connector light shows amber while charging and green when full. No light means no power is arriving.
• Wattage. A small phone charger may not deliver enough power to wake a fully drained MacBook. Use the adapter that came with it or one rated similarly.

Leave it plugged in with a known-good charger for at least 30 minutes before trying again. A deeply drained battery may not show any sign of life right away.

Step 2: Hold the power button

Press and hold the power button (the Touch ID button on newer models) for about 10 seconds, then release. Wait a moment and press it once normally. If the Mac was frozen with its screen off, this forces a shutdown so it can start fresh.

Step 3: Reset power management, depending on your Mac

How you do this depends on whether your MacBook uses Apple silicon or an Intel processor.

• Apple silicon (M-series chips): there's no separate SMC reset. Shutting down fully, waiting a few seconds and starting up again does the same job. NVRAM is checked automatically at startup.
• Intel MacBooks: the SMC reset steps differ depending on whether the Mac has Apple's T2 security chip. NVRAM can be reset by holding Option, Command, P and R at startup. Apple's support site lists the exact key combination for each type.

If you can't open About This Mac to check, look at the original box or receipt. Every MacBook model released from 2021 onward uses Apple silicon, while 2020 models can be either.

Step 4: Is it the display or the power?

If you saw or heard signs of life, test the screen:

1. Press the brightness-up key several times. Brightness can get turned all the way down by accident.
2. Close the lid, wait a few seconds and open it again.
3. Connect an external monitor or TV. If the picture appears there, the Mac is running and the problem is the built-in display or its connection.
4. Shine a flashlight at the screen at an angle. A very faint image means the backlight has failed rather than the whole display.

Step 5: Think about liquid

If anything spilled on the MacBook recently, even days ago, stop trying to turn it on. Power running through wet circuits is what does the most damage.

1. Unplug it and hold the power button to make sure it's off.
2. Open it and stand it upside down in a tent shape, keyboard facing down, so liquid can drain out.
3. Don't use a hair dryer, an oven or rice.
4. Get it checked even if it seems to recover. Corrosion can keep working on the board long after the liquid dries.

Step 6: A few last checks

• Unplug every accessory: hubs, drives, docks and displays. A faulty accessory can stop a Mac from starting.
• If the MacBook was very hot or very cold, let it reach room temperature first.
• If the trackpad is suddenly hard to click or the case looks raised, the battery may be swelling. Stop charging it and have it looked at.

What about your files?

On Apple silicon MacBooks, the storage is built onto the main board, so getting files back usually depends on getting the Mac working again. If you use Time Machine or iCloud Drive, your files may already be safe. If not, mention it when you ask for a quote so the repair approach takes your data into account.
