If you find yourself in a situation where your Mac won’t start due to a dead battery, you might be wondering how to get it up and running again. Fear not, as this step-by-step guide will walk you through the process of starting your Mac with a dead battery. Whether you’re facing an emergency or simply need to power on your device without a functional battery, these easy-to-follow instructions will help you troubleshoot and revive your Mac in no time.

3. Keep holding the Shift key until the Apple logo or a progress bar appears on the screen.
4. Release the Shift key once you see the login window or the desktop.
In Safe Mode, your Mac may take longer to boot up as it performs additional diagnostics. It may also disable or modify certain features, such as iCloud syncing and file sharing. If your Mac successfully starts up in Safe Mode, you can proceed with troubleshooting and identifying the root cause of the dead battery issue.
Utilizing Recovery Tools And Options
Utilizing recovery tools and options can be a helpful solution when starting your Mac with a dead battery. These tools and options can assist in troubleshooting and resolving any software-related issues that may be preventing your Mac from booting up.
One of the most effective recovery tools is the macOS Recovery utility, which is built into all Macs. To access it, press and hold the Command + R keys while turning on your Mac. This will boot your Mac into the recovery mode.
Once in the recovery mode, you can utilize options such as repairing the startup disk using Disk Utility, reinstalling macOS, restoring your Mac from a Time Machine backup, or even utilizing the Terminal to perform advanced troubleshooting.
If the issue is related to a corrupted startup disk or problematic software, utilizing recovery tools can resolve the problem and allow your Mac to start up successfully. However, if the issue persists, it may be necessary to explore additional options or seek professional assistance to identify and fix the underlying problem.
Using An External Power Source Or Alternate Charging Methods
If your Mac’s battery is completely dead and you’re unable to power it on, you can try using an external power source or alternate charging methods to get it up and running. This method can be useful in situations where you don’t have access to your regular charging cable or if it’s malfunctioning.
One option is to use a different charging cable or adapter. Sometimes, the issue lies with a faulty cable, so using a different one might help. Additionally, you can try charging your Mac using a different power outlet or a USB port on another device. Be sure to use a high-quality cable and a reliable power source.
If none of these options work, you can consider alternative charging methods such as using a power bank or a car charger. Power banks are portable and convenient, allowing you to charge your Mac on the go. However, make sure the power bank has enough capacity to deliver power to your Mac.
Keep in mind that using an external power source or alternate charging methods should be temporary solutions. It’s important to diagnose the underlying battery or charging issue and address it properly to ensure long-term functionality for your Mac.
Resetting The System Management Controller (SMC)
Resetting the System Management Controller (SMC) on your Mac can be an effective solution for starting up your device with a dead battery. The SMC controls various hardware functions, including power management, thermal management, and battery charging.
To reset the SMC, follow these steps:
1. Shut down your Mac completely.
2. Connect your Mac to a power source using the AC adapter.
3. Press and hold the following keys simultaneously for about 10 seconds: Shift + Control + Option + Power button.
4. Release all the keys at the same time.
5. Turn on your Mac by pressing the power button.
By resetting the SMC, you are essentially rebooting the power management system of your Mac. This may help resolve issues related to a dead battery and can potentially allow your Mac to startup.

It’s important to note that a dead battery could signify a larger issue with your Mac’s hardware, so professional help may be necessary for a comprehensive diagnosis and repair.
Employing Target Disk Mode
Target Disk Mode is a feature available on Mac computers that allows you to use your dead battery Mac as an external hard drive, enabling you to access your files and data. This mode is particularly useful if you need to retrieve important documents or transfer files from your dead battery Mac to another Mac.
To utilize Target Disk Mode, follow these steps:
Step 1: Connect both Macs using a FireWire or Thunderbolt cable.
Step 2: Start your dead battery Mac and hold down the T key during startup until the Thunderbolt or FireWire symbol appears on the screen.
Step 3: Your dead battery Mac will now be recognized as an external drive by the other Mac. You can access its files and folders just like any other external hard drive.
Step 4: Copy the necessary files from your dead battery Mac to the other Mac.
Step 5: Once you have successfully transferred your files, eject the external drive and safely disconnect the cable.
Employing Target Disk Mode provides a convenient solution to retrieve data from your Mac with a dead battery. However, remember that this method requires access to another functioning Mac.
Troubleshooting Startup Disk Issues
When starting your Mac with a dead battery, you may encounter various issues related to the startup disk. These issues can prevent your Mac from booting up properly. Troubleshooting startup disk issues can help resolve these problems and get your Mac up and running smoothly.
