How to Fix a MacBook That Charges but Won't Turn On

To fix a MacBook that charges but won't turn on, check its power connection, hold Power for about 10 seconds, then release it and press it normally. If it still will not start, disconnect accessories and repeat the procedure. A charging indication alone does not establish that your Mac can start.

Begin with the charger and power button before moving to the procedure for your Mac's processor. Safe mode and Recovery apply only when your Mac powers on far enough to reach them.

Check the charger and power connection

Inspect the charging cable for damage and stop using damaged charging hardware. Securely connect a compatible adapter to your MacBook and a working wall outlet. Try another compatible cable and adapter if you have them.

If your battery is depleted after long-term storage, leave your Mac connected to its appropriate adapter for 20 minutes before trying again. Apple documents this delay for that low-battery condition. It is not a guaranteed repair for other startup faults.

For a MacBook using a USB-C power adapter, unplug the adapter from the wall for 30 seconds, then reconnect it. If a line-noise problem returns, try an outlet on another electrical circuit or a UPS. Use a USB-C cable that supports charging, and stop using one that works only when moved or wiggled.

For an adapter with a removable wall plug, try another Apple AC plug or an Apple Power Adapter Extension Cable. You can also try another USB-C cable that supports charging.

On a MacBook that charges over USB-C and has more than one USB-C port, try another of those ports, because Apple says any of them can be used for charging. On a MacBook with a single USB-C port, such as the 12-inch MacBook (Early 2015), try another compatible cable or adapter instead. If your model supports both MagSafe and USB-C charging, try a suitable USB-C cable and adapter instead of MagSafe.

When charging is intermittent or interrupted by heat, move your Mac to a cool, ventilated location. Apple specifies an ambient operating range of 50 to 95°F (10 to 35°C). Disconnect the charging connection and remove debris with a soft, dry, lint-free cloth.

A repeatedly flashing amber MagSafe 3 light needs a separate check. Disconnect the cable from your Mac and adapter, unplug the adapter, wipe the MagSafe connector and port with a dry cloth, and check the USB-C connection for debris. Attempt a restart, then reconnect everything. If the flashing continues, try charging with another MagSafe 3 cable or USB-C cable.

Force a shutdown and disconnect accessories

Hold Power for about 10 seconds to force a complete shutdown. On a MacBook with Touch ID, physically press and hold Touch ID. Release it, then press and release it normally to restart your MacBook using its power button.

Unplug external drives, hubs, printers, phones, and other accessories if startup still fails. Leave the charger connected and repeat the 10-second power-button procedure. These steps apply to both Intel and Apple silicon MacBooks.

Check whether the screen is asleep or dim

Click the trackpad to wake a MacBook that is powered on but appears off. If the display returns, your Mac was asleep. For a dim display, press Increase Brightness, or use the Control Strip on a model equipped with a Touch Bar.

With a visible interface, open Apple menu > System Settings > Displays and raise the Brightness slider. For a powered-on Mac with a dark screen, continue with power but no display troubleshooting. If waking or brightening it does not help, try the applicable startup checks below.

Use the right power management procedure

On an Apple silicon MacBook, connect power and use Apple menu > Restart if macOS is accessible. Otherwise, restart a computer that is not responding with the power-button shutdown and startup procedure above. Apple says power management resets automatically on Apple silicon, so an Intel SMC key sequence is not needed.

For an Intel MacBook Air or MacBook Pro with Apple's T2 chip, shut down first. Hold Left Control + Left Option + Right Shift for 7 seconds, then keep holding them and add Power for another 7 seconds. Release everything, wait a few seconds, then press Power.

On an Intel MacBook without T2, shut down and use the built-in keyboard. Hold Left Shift + Left Control + Left Option + Power together for 10 seconds. Release all the keys, then press Power to start your Mac.

Try safe mode when normal startup fails

Safe mode is an option when your MacBook powers on but fails during normal startup. On Apple silicon, shut down, then hold Power until startup options appear. Select the startup volume, hold Shift, and click Continue in Safe Mode.

For an Intel MacBook, turn it on and immediately hold Shift until the login window appears. Log in, and log in a second time if requested. Look for Safe Boot to confirm the mode.

If startup reaches the login window but stalls around login, temporarily bypass login items. Hold Shift while clicking Log In, then release it when the Dock appears. With automatic login, hold Shift when the startup progress bar appears and release it after the desktop appears.

Open Recovery and repair the startup disk

On Apple silicon, shut down and hold Power until startup options appear, then click Options > Continue. On Intel, turn on your Mac while holding Command + R until an Apple logo or globe appears. If prompted, select the startup volume and click Next, then select an authorized user, click Next, and enter that user's login password.

An Intel MacBook supporting Internet Recovery has another route if local Recovery fails. Hold Option + Command + R at startup and connect to the internet. If a globe warning appears, try another network, Ethernet instead of Wi-Fi, or Shift + Option + Command + R at startup. You can also retry later.

In Recovery, select Disk Utility and click Continue. Choose View > Show All Devices. Starting at the bottom of the disk's volume list, select each volume, click First Aid, then click Run.

Work upward through the volumes, then the containers, and finally the device itself. Quit Disk Utility and choose Apple menu > Restart. Use Recovery and Disk Utility instead of older instructions involving Command + S, because Apple says single-user mode is disabled in macOS Mojave or later.

Reinstall macOS if disk repair does not help

If your Mac reaches Recovery and has a usable startup disk, try an ordinary macOS reinstallation without erasing first. Apple says this preserves apps and personal data, though you should back up if possible before starting. Select the macOS installation or reinstallation option in Recovery and click Continue.

Unlock the disk with your login password if requested. If offered Macintosh HD and Macintosh HD - Data, choose Macintosh HD. Keep power connected and the lid open until installation finishes.

Revive firmware with another Mac

For an Apple silicon or T2 MacBook with suspected firmware failure, you can try a firmware revive, which preserves data. You need another internet-connected Mac running macOS 14 or later and a USB-C cable that supports both data and charging. Apple specifies that you should not use a Thunderbolt 3 cable for this procedure.

First, identify the affected MacBook's DFU port by facing its left-side ports. Use the rightmost port for T2 MacBooks, MacBook Air models introduced in 2025 or later, and 14-inch MacBook Pro models with base M4, M5, or M6 chips. Use the leftmost port for other Apple silicon MacBook Pro and MacBook Air models, and for MacBook Neo.

Connect both Macs to power, using MagSafe for the affected Mac if available. Disconnect other USB devices, then connect the affected Mac's DFU port directly to the working Mac with the data-and-charging cable. Shut down the affected Mac.

On the affected Mac, press and release Power, then immediately hold Left Control + Left Option + Right Shift + Power. For Apple silicon, hold all four for 10 seconds, release everything except Power, and keep holding it for up to 10 more seconds. For T2, hold all four for about 3 seconds. If the working Mac prompts you to allow the connection, release the keys and click Allow.

If the connected Mac is missing from the working Mac's Finder sidebar, open Finder > Settings > Sidebar. Select CDs, DVDs, and iOS Devices, then select Mac under Locations. In Finder, click Revive Mac, then click Continue. Keep the working Mac awake during the revive.

A firmware restore erases your Mac. If revival fails and you choose to proceed, use the same DFU setup, click Restore Mac, then click Restore and Update. Complete activation and setup afterward. T2 models also require macOS reinstallation through Recovery.

Run diagnostics and arrange service if needed

To run Apple Diagnostics, disconnect unnecessary peripherals, connect power, and place your Mac on a ventilated hard surface. On Apple silicon, hold Power until Options appears, release it, then hold Command + D until your Mac restarts. On Intel, hold D at power-on; try Option + D if necessary.

Choose a network if requested, and click Run Offline when that button is offered, unless Apple Support or a repair technician has initiated an online Apple Diagnostics session. In macOS Tahoe 26 and later, select the relevant diagnostic when prompted, including a display test for a display problem; earlier versions run tests automatically. Record any reference codes to provide when arranging service.

If your MacBook cannot enter diagnostics or still cannot start after the applicable checks, contact Apple to arrange a hardware assessment. Bring your Mac and its charging hardware, and provide any diagnostic reference codes. Repair availability depends on your model and region.

Frequently Asked Questions

Should you reset NVRAM when a MacBook will not turn on?

An NVRAM reset addresses stored startup disk or display settings on Intel MacBooks, not a complete lack of power, and affected settings may need readjustment afterward. Shut down, turn on your Mac, and immediately hold Option + Command + P + R for about 20 seconds. Release the keys and readjust affected settings after startup. Apple's NVRAM reset steps do not apply to Apple silicon.

Can closing the lid help with a charging problem?

For a suspected charging problem, shut down your Mac and close its display for 30 seconds. Open it, then retry charging and startup.

Will connecting two chargers help a depleted MacBook start faster?

Connecting multiple chargers does not accelerate charging. Use one charging source.

Which macOS version does Intel Internet Recovery offer?

Starting Internet Recovery with Option + Command + R can offer the latest compatible macOS. Using Shift + Option + Command + R can offer the original version or the nearest available version. These combinations apply to Intel MacBooks supporting Internet Recovery.
