What You'll Learn
Try a hard reboot
If your Mac is not waking up from sleep mode, there are several quick fixes you can try. You can tap your Mac's trackpad, press Return or another key on the keyboard, or click the mouse. You can also press the Power button to remove your Mac from hibernation mode. If none of these work, you can try a hard reboot.
A hard reboot, also known as a force restart, is a way to resolve system issues on your Mac. It is a good option if your Mac is experiencing technical issues such as a frozen or unresponsive screen. A hard reboot can also help fix issues when your Mac won't restart after updating, or when the mouse cursor, keyboard, or trackpad is not responding. Additionally, a hard reboot can clear the memory and cache, improving your Mac's overall performance.
Before performing a hard reboot, it is important to note that it will delete all unsaved data and changes, and reset all system settings to factory settings. Therefore, it is recommended to only perform a hard reboot if all other fixes have failed to resolve the issue.
To perform a hard reboot on your Mac, simply press and hold the Power button for a few seconds, then press the Power button again to restart your device. If your Mac still won't wake up, try charging it for at least an hour and then reboot again. If this also doesn't work, you can try rebooting your Mac in Safe Mode. To do this, shut down your Mac, then press and hold the Power button until the startup options appear. Select your startup disk and press the Shift key, then click "Continue to Safe Mode" and release the Shift key.

Reset the SMC
Resetting the SMC, or System Management Controller, can resolve certain issues related to power, including waking up your Mac from deep sleep. The SMC is a subsystem on the Mac that manages low-level processes, including sleep, wake, hibernation, and battery supply, among others.
If your Mac is equipped with an Apple Silicon chip, resetting the SMC is simple and only requires a reboot. However, for Intel-based Macs, a more detailed process is required. To reset the SMC on an Intel-based Mac, follow these steps:
- Press the Power button to turn on your Mac.
- Immediately press and hold the following keys: Option, Command, P, and R.
- Continue holding the keys for approximately 20 seconds.
- Release the keys after hearing the Mac start-up sound for the second time.
If your Mac still fails to wake up from deep sleep after resetting the SMC, there are a few other advanced methods you can try. Firstly, ensure that your Mac is charged by connecting it to a power source and allowing it to charge for at least an hour. Then, try rebooting your Mac by pressing and holding the Power button for a few seconds, followed by pressing the Power button again.
If basic fixes don't work, you may need to try more advanced methods. One such method is to run First Aid on Disk Utility. To do this, go to Finder, select Applications, then Utilities, and finally, Disk Utility. Choose your Start-Up Disk, click First Aid, and then Run. After running First Aid, restart your Mac and check if it wakes up from deep sleep properly.
In some cases, applications running in the background may prevent your Mac from waking up. To address this, boot your Mac in Safe Mode and uninstall any unnecessary applications. To enter Safe Mode, shut down your Mac, then press and hold the Power button until the startup options appear. Select your startup disk and press the Shift key, then click Continue to Safe Mode and release the Shift key.
If none of these solutions work, it is recommended to contact Apple Support or visit an Apple Service Center for further assistance.
