Mac Won't Wake Up & Unresponsive: How to Fix MacBook Sleep Failure

A sleeping Mac can disrupt productivity, but thankfully, this is a common problem with easy solutions. This guide provides troubleshooting steps to wake your Mac from sleep.

Waking a Sleeping Mac:

For MacBooks, try tapping the trackpad, pressing a key, or clicking the mouse. Opening the lid also works. If these fail, briefly press the power button to reboot.

Troubleshooting a Mac That Won't Wake Up:

If your Mac refuses to wake, try these solutions:

1. Basic Wake-Up Attempts: For MacBooks, try the trackpad, keyboard, or mouse. For iMacs, proceed to the next step.

2. Power Button: Press the power button to try waking the Mac from sleep mode.

3. Reboot: Hold the power button until the Mac shuts down, then press it again to restart.

4. Reset the SMC (System Management Controller):

   • Hold the power button for 10 seconds to shut down.
   • Disconnect the power adapter for 15 seconds.
   • Reconnect the adapter, wait 5 seconds, and press the power button to restart.

More Advanced Troubleshooting:

If the above steps don't work, consider these more in-depth solutions:

1. Check the Power: Ensure your MacBook is adequately charged. Plug it in for 30 minutes, then try the power button.

2. Remove External Devices: Disconnect any external devices. These can sometimes interfere with sleep functions. Eject devices through Finder before disconnecting.

3. Reset SMC (already described above).

4. Force Restart: Hold down the power button until the Mac shuts down completely. Wait, then press the power button to restart. Use this as a last resort.

5. Reset NVRAM/PRAM:

   • Shut down your Mac.
   • Hold down Command-Option-P-R keys.
   • Power on your Mac and keep holding the keys until it restarts.
   • Release the keys.

6. Check for System Updates: Go to Apple menu > About This Mac > Software Update to install any pending updates.

7. Check for Malware: Use antivirus software (e.g., MacKeeper's Antivirus) to scan for and remove malware. This can significantly impact system performance and sleep functionality.

Reviving Your Mac:

Addressing Mac sleep issues often involves a systematic approach. While basic steps often suffice, malware can be a hidden culprit. Antivirus software provides an extra layer of protection against performance issues and unexpected shutdowns.
