Introduzione

If you have done a logic board or battery replacement, you can reset your MacBook's SMC. You may also use this as a first-aid measure if you’re having power issues with your MacBook.

    • First, determine whether the battery is removable.

    • These models have a non-removable battery:

      • MacBook Pro (Early 2009) and later

      • all models of MacBook Air

      • MacBook (Late 2009)

      • MacBook (Retina, 12-inch, Early 2015) and later

    • Shut down your Mac.

    • Unplug the MagSafe or USB-C power adapter from your computer.

    • Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds.

    • Release all keys.

    • Reconnect the power adapter.

    • Press the power button again to turn on your Mac.

    • Shut down your Mac.

    • Disconnect the MagSafe power adapter from your computer.

    • Remove the battery.

    • Press and hold the power button for 5 seconds.

    • Reconnect the battery and MagSafe power adapter.

    • Press the power button to turn on your Mac.

    • The LED on the MagSafe power adapter might change colors or temporarily turn off when you reset the SMC.
