Preliminary Fixes

• Press the power button: Sometimes, a simple press of the power button can help resolve the issue. Press and hold the power button for a few seconds. You might see the screen flash or hear a chime indicating that the MacBook is attempting to wake up.
• Check MacBook battery: A depleted battery can prevent your MacBook from waking up from sleep mode. To check, go to System Settings > Battery > Battery Health to view the battery status. If it says Service Recommended, the battery may need to be replaced.
• Check error log: Examining the system logs can help identify any issues causing the sleep/wake problem. To check, go to Applications > Utilities > Console > type wake or sleep in the search bar. Look for any errors or warnings around the time you attempted to wake the MacBook.
• Update macOS: Keeping macOS up to date can resolve bugs that may cause sleep issues. Go to System Settings > General > Software Update. If updates are available, click Update Now to download and install them. Follow the on-screen instructions to complete the process.
