はじめに

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.

    • These MacBooks have a T2 security chip:

    • MacBook Air introduced in 2018 or later

    • MacBook Pro introduced in 2018 or later

    • If it has a T2 chip you can reset the SMC as follows (if not, skip this step):

    • Hold the "Control" and "Option" (Alt) on the left side of your keyboard and the "Shift" on the right side of your keyboard for 7 seconds.

    • Then additionally press and hold the power button and keep holding all four keys for another 7 seconds, then release them.

    • Press the power button after few seconds to turn on your MacBook.

    • These models have a non-removable battery (per Apple definition):

    • MacBook Pro (Early 2009) and later

    • all models of MacBook Air

    • MacBook (Late 2009)

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

    • Proceed with the next step to reset your SMC.

    • For other models skip this and the next step.

    • 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.

終わりに

The SMC of your MacBook has now been reset.

Il mio MacBook Pro 2019 nuovo di 3 mesi non vuole accendersi.

Ieri sera con la batteria 1% ho spento il mac. Stamattina non vuole avviarsi, non da segni di vita.

Il mac fa solo un suono quando attacco il caricatore, poi nulla. Dopo 2 ore in carica niente.

Cosa mi consigliate?

Grazie
