How to Fix a Mac That Won't Turn On

Multiple measures can be employed to prevent the system from booting up. However, prior to that, it's crucial to ensure the safety of your data. It's imperative to comprehend that data loss can occur despite taking preventive steps.

Here are the solutions you can attempt to resolve the issue:

1. Fix 1: Check power connections
2. Fix 2: Unplug accessories
3. Fix 3: Check for a depleted battery
4. Fix 4: Use a different power cable or adapter
5. Fix 5: Boot your Mac in Safe Mode
6. Fix 6: Perform a Power Cycle
7. Fix 7: Reset the SMC or T2 chip

Fix 1: Check power connections

The most straightforward solution to fixing a Mac that won't turn on is to verify the power connection. Sometimes, you might have inadvertently left the power switch off. However, there are other factors to take into account as well. For example, inspect the power outlet to ensure it's functioning properly.

Another aspect to examine is the AC power cable of the charger. Carefully inspect the power cord for any signs of damage from usage or wear and tear. Ensure that it is properly inserted into the charger. Additionally, you can attempt to use a different adapter to see if the device powers on.

Fix 2: Disconnect Accessories

The next step to resolve the issue of the Mac not turning on is to disconnect all accessories or external devices. The SMC (System Management Controller) has a safety mechanism that shortens the power-on process if the system encounters excessive current or short circuits caused by external devices. This prevention measure stops the system from powering on. By removing these accessories, you can ascertain whether the problem is resolved or not.

Fix 3: Check for a flat battery

Did you check if your system has a dead battery? Extended periods of non-use or the age of the device can cause a complete discharge of the battery. In such cases, the system won't power on.

MacBook models from before 2012 feature a battery check button and a battery status indicator. Press the button and observe if any light appears. If there's no light, it indicates that the battery is depleted.

If your Mac isn't turning on due to a depleted battery, use a functioning charger to power up the system and turn it on. However, certain models require a minimum battery level to initiate the startup process. In such cases, you'll need to let the charger charge the battery to the required level before it will turn on.

If you don't see any light on the connector, the charger isn't functioning properly. However, if you observe an orange or green light, it indicates that the SMC (System Management Controller) and charger are operational. Wait for a few minutes, then attempt to turn on the system by pressing the power button.

Fix 4: Try a different power cable or adapter

Perhaps the issue doesn't lie with your system. In certain instances, defective power cables can prevent a Mac from powering on. Therefore, it's essential to try a different compatible power cable to determine if this resolves the problem.

Another aspect to consider is the power adapter. If you experience frequent power outages, it could potentially damage the adapter. In such a scenario, purchasing a new adapter and attempting to turn on your Mac might be necessary.

Fix 5. Start up your Mac in Safe Boot

Safe mode runs various diagnostics to identify issues with your system. Occasionally, starting up your Mac in Safe Mode (Mac Safe Mode) effortlessly resolves the problem.

Check out the steps you need to follow:

For Intel-based Mac:

Step 1. Boot up the system.

Step 2. Press and hold the Shift key.

Step 3. Wait for the Apple logo to appear on the screen.

Step 4. Release the Shift key when you see the login window, then log in.

For Mac with Apple Silicon –

Step 1. Press and hold the power button.

Step 2. Hold down the button until you see the startup options window.

Step 3. Choose your startup disk.

Step 4. Press and hold the Shift key.

Step 5. Select Continue in Safe Mode. Release the key.

Fix 6: Perform a Power Cycle

Before proceeding with the power cycle, it's important to understand the different states of your Mac: Off, On, and Sleep.

Performing the power cycle involves ensuring the system transitions towards the Off state. To carry out the power cycle, hold down the power button for ten seconds. Once that time has elapsed, release the button. At this point, your Mac will be in the OFF state. To power on the system again, simply press the power button.

If this solution does not fix the issue, you must proceed with the following steps.

Fix 7: Reset the SMC or T2 chip

SMC oversees the entire power-on procedure. While SMC operates effectively, issues can arise at any time. In such instances, you'll need to perform an SMC reset.

Here are the steps to reset the SMC for a system with an non-removable battery: 1. Shut down your Mac: Turn off your computer completely by selecting "Shut Down" from the Apple menu in the top-left corner of your screen. 2. Unplug the power adapter: Disconnect your Mac from any power source, including the magnetic power cable if it's a laptop. 3. Press and hold the left Shift + Control + Option keys: Locate these keys on the left side of your keyboard, and press and hold them simultaneously. 4. Press and hold the Power button: While still holding the Shift + Control + Option keys, find the Power button (usually located on the right side of the keyboard) and press it as well. 5. Release all keys and the Power button at the same time: After about 10 seconds, let go of all keys and the Power button together. 6. Boot up your Mac: Press the Power button again to turn on your computer. The SMC reset is now complete. 7. Reconnect the power adapter: If applicable, plug the power adapter back into your Mac. Your Mac should now have its System Management Controller (SMC) reset. If you were experiencing issues related to hardware control or power management, they should be resolved after this process.

Step 1. Press and hold the power button to turn off the system. Connect the charger.

Step 2. Press and hold the Shift, Control, and Option keys, along with the power button, all at the same time.

Step 3. Hold them for at least ten seconds. Release the buttons.

Step 4. Press the power button to turn on the system.

• If your system has a removable battery, follow the steps to reset the SMC:

Step 1. Press and hold the power button to turn off the system.

Step 2. Remove the battery and power adapter from the system.

Step 3. Press and hold the power button for 5 seconds.

Step 4. Insert the battery back into the system.

Step 5. The SMC is reset.

For systems with a T2 chip, follow the steps to reset the SMC:

Step 1. Press and hold the power button to turn off the system.

Step 2. Hold down the Control, Option, and Shift keys together for a few seconds.

Step 3. Press the power button and hold it down as well.

Step 4. Hold down all the keys for a few more seconds. Now, release the keys.

Step 5. After some time, turn on the system by pressing the power button.
