What is the MacBook won’t turn on issue?
The “MacBook won’t turn on” problem is when a MacBook computer doesn’t start up or turn on correctly. When this happens, the MacBook may not show any signs of life, such as a blank screen, no sounds, and the power button that doesn’t do anything. There are many reasons why a MacBook might not turn on, including hardware and software problems. Some of the most common reasons are a dead battery, a broken power adapter or charging cable, a broken hardware part, a program conflict or crash, or a problem with the operating system.
Common Reasons for MacBook Not Turning On
- Power problems: Make sure the MacBook is fully plugged into a power source and that the power adapter works. Check to see if the battery is charged or try a different plug or charger.
- Hardware problems: The MacBook won’t turn on if its hardware, like the processing board, RAM, or hard drive, is broken. In this case, it may need to be fixed or replaced by a professional.
- Software problems: Sometimes, a MacBook won’t turn on because of problems with the software. This could be caused by a bad operating system, software that doesn’t work well together, or a failed software update. Software problems might be fixed by trying to boot in Safe Mode or by using recovery tools like Disc Utility or reinstalling macOS.
- Problems with the screen or graphics card: If the MacBook’s screen stays black or shows skewed images, the screen or graphics card may be broken. By hooking up an external monitor, you can find out if the problem is with the internal display or with the graphics technology.
- Problems with the battery: If the battery is bad, the MacBook won’t turn on. If the battery can’t hold a charge anymore or is broken, it might need to be changed.
- Overheating: If a MacBook gets too hot, it might shut down or refuse to turn on. Check to see if the MacBook’s fan is working right, and clean the vents of any dust or other debris that might be blocking them.
Ways to Fix ‘MacBook won’t turn on’ issue: Air and Pro models
Reset the SMC (Non-M1 Mac)
If your MacBook Pro won’t turn on even though it’s charging, you should check the System Management Controller, which is in charge of the whole process of turning on your MacBook. Your MacBook won’t turn on if the SMC doesn’t have power or hasn’t given a power source to the hardware circuit. To reset the SMC on a MacBook with a built-in battery, do the following:
On a MacBook with a battery that can’t be taken out:
- Hold down the power button/Touch ID button for 10 seconds to turn off your Mac.
- Use a good power adapter to charge your Mac.
- For 10 seconds, hold down the Shift, Control, and Option keys with your left hand and the power button/Touch ID button with your right.
- Put all the keys down.
- Try pressing the power button or the Touch ID button to see if the problem goes away.
To reset the SMC on a MacBook whose battery can be taken out:
- Hold down the power button/Touch ID button for 10 seconds to turn off your Mac.
- Take out your MacBook’s battery.
- Wait a few minutes until the battery is totally gone.
- Turn on your MacBook again after you put the battery back in.
Perform a power cycle for Intel Macs
If your MacBook won’t turn on when you press the power button or open the lid, you can do a power cycle to cut power to it and restart it.
- On a laptop Mac, hold the power button/Touch ID key for 10 seconds.
- If you have a spinning hard drive disk, you will hear a squeak. If you have a solid-state drive, you won’t hear anything.
- On a desktop Mac, alternatively, you can directly unplug Mac’s power cord for 10 seconds and plug it back to power.
- This will force your Mac to return to the Off state and start refreshed.
- If you fail to fix the Mac that won’t restart, you need to troubleshoot Mac’s display.
Detach all external devices from your Mac
During the power-on process, your computer does a full hardware check of both its internal parts and any external devices that are connected to it. A broken accessory could stop your MacBook from turning on. Most of the time, it’s an accessory that has bad connections, a short circuit, or uses an odd amount of power.
- Unplug all the external devices attached to the computer, including printer cable, external disks, HDMI cables, USB cables, second screen, Magsafe charger, mouse, and etc.
- Then press the power button/Touch ID button on your MacBook again.
- This procedure should work on all Apple Silicon and Intel-based Mac Models (MacBook Pro, MacBook Air, Mac Pro, Mac Mini, and iMac).
Check the display brightness settings or try to use an external monitor
If you can’t see any pictures or movies on your screen, your MacBook Pro might not turn on because you turned the brightness of the monitor all the way down without realizing it.
- Press the brightness up button a few times on your keyboard or on your Touch Bar on newer MacBook Pro models to increase the screen brightness.
- You can also press the Caps Lock key to confirm your Mac is running if the light is on. If you can get some dim image or still no image on your screen, your Mac has a backlight problem.
- Connecting an external monitor will give you the chance to use your Mac until the original screen is repaired.
Charge the MacBook for 5 minutes or longer
If you haven’t turned on your MacBook in a while or if the battery or power adapter is dead or broken, it won’t turn on at all. Most Mac laptops will turn on as soon as you plug in a working power charger, but some models need a certain amount of battery power for the System Management Controller (SMC) to be activated. So, we suggest you wait a few minutes until the power on your battery hits that minimum level. Extremely cold or hot weather can sometimes make it hard for a battery to charge.
- It could take a couple of hours before your Mac’s battery finally charges enough to send the power supply to your Mac.
- It is recommended to charge your Mac with an original power adapter in such temperature conditions to save time.
- Then press the power button/Touch ID button again to see if your MacBook turns on.
- If still, MacBook Pro won’t power on, do the following to force start the Mac.
