Why Does Your MacBook Keep Turning Off Suddenly?

When trying to fix a MacBook that keeps turning off suddenly, understanding the root cause is the first step. Although the issue looks similar each time, the underlying problem can vary widely.

1. Battery Health Failure or Reduced Charging Capacity

A weak or aging battery is one of the most common reasons your MacBook keeps shutting down unexpectedly.

• The battery may no longer hold charge.
• The system may be unable to regulate power delivery.
• macOS may misread battery percentage and trigger shutdowns.

2. Overheating Issues Causing Automatic Shutdown

Even though macOS is engineered to manage temperature, excessive heat forces the system to protect itself by powering off.
Dust buildup, heavy apps, or blocked vents can all contribute.

3. Power Management Glitches in macOS

A corrupted SMC or NVRAM can cause the MacBook to switch off suddenly without warning.

4. Faulty Charging Port or Cable

Even a slightly loose charger can cause sudden power loss, especially during performance-heavy tasks.

5. Logic Board or Power IC Failure

If the logic board is damaged, the MacBook may shut off intermittently, restart repeatedly, or fail to power on completely.
