If⁣ your MacBook Pro won’t turn on, a common troubleshooting step is‍ to reset the System Management Controller (SMC). The SMC ​is ⁣responsible ⁤for managing a variety‍ of‌ hardware functions, including power management, battery charging, and fans.

To reset​ the ⁣SMC on a MacBook Pro‌ with a non-removable ‍battery, ​follow these steps:

Step Instructions
1 Shut down your MacBook Pro.
2 Press ⁤and‌ hold the Shift, Control, and Option keys ⁢on the​ left side of ‌the keyboard, then press the power ​button at the same ⁢time.
3 Release all keys and ‌the power button at the‍ same time.
4 Press the power button again to turn on your MacBook Pro.

If your MacBook Pro has a removable battery, the ⁣SMC⁣ reset process is⁢ slightly‍ different. Refer to Apple’s⁤ official support documentation for specific⁣ instructions based on your model.
