Introduction: Your MacBook Won’t Start – What to Do
A MacBook that refuses to turn on can disrupt work and daily tasks. Using a structured troubleshooting checklist can help identify the cause efficiently. At DRA-3C Laptop Repair, we deal with macbook 無法開機 frequently and have developed a complete guide to address both hardware and software issues.
Step 1: Check Power Supply and Battery
Ensure the charger and cable are working, and the power outlet is functional. Check for MagSafe LED indicators or USB-C charging icons. A completely drained or faulty battery is often the simplest explanation for a MacBook that won’t start.
Step 2: Power Cycle the Device
Disconnect the charger, hold the power button for ten seconds, then reconnect the charger and press power again. This clears temporary system glitches and may allow the MacBook to boot.
Step 3: Reset SMC and NVRAM/PRAM
Reset the System Management Controller (SMC) for power-related issues. Intel models: Shift + Control + Option + Power for ten seconds. T2 chip models: seven-second procedure. Reset NVRAM/PRAM by holding Command + Option + P + R for 20 seconds during startup to fix system configuration errors.
Step 4: Boot in Safe Mode
Safe Mode disables non-essential startup programs and runs system checks. Hold Shift while starting the MacBook. If it boots, uninstall any recently added software that may cause conflicts.
Step 5: Disconnect External Devices
Remove USB drives, hubs, and external monitors. Attempt startup. If successful, reconnect peripherals individually to locate the problem.
Step 6: Recovery Mode and Disk Utility
If software corruption is suspected, boot into Recovery Mode (Command + R) and use Disk Utility to repair the startup disk. Reinstall macOS if needed.
Step 7: Professional Repair for Hardware Issues
If none of the steps resolve the problem, professional repair is required. DRA-3C Laptop Repair handles logic board failures, battery replacement, SSD repair, and other hardware issues safely. Attempting DIY repairs can worsen macbook 無法開機 problems.
Step 8: Preventive Measures
