To reset the SMC (System Management Controller) on your computer, follow these steps:
1. Shut down your computer: Begin by completely shutting down your computer. This can be done by selecting the “Shut Down” option from the Apple menu or by pressing and holding the power button until the computer powers off.
2. Disconnect the MagSafe power adapter: If your computer is connected to the MagSafe power adapter, unplug it from the computer. This step ensures that there is no power source connected to the computer during the SMC reset process.
3. Remove the battery (if applicable): If your computer has a removable battery, remove it from the battery compartment. Not all Mac models have removable batteries, so if your Mac does not have one, you can skip this step.
4. Press and hold the power button: With the MagSafe power adapter and battery disconnected (if applicable), press and hold the power button on your computer for about 5 seconds. This step is important as it helps discharge any remaining power in the system.
5. Release the power button: After holding the power button for 5 seconds, release it. At this point, there should be no power source connected to your computer, and the SMC reset process is about to be initiated.
6. Reconnect the battery and MagSafe power adapter: If you removed the battery in step 3, reinsert it into the battery compartment now. Next, connect the MagSafe power adapter back to your computer. Ensure that it is securely plugged in and that the LED on the MagSafe connector lights up.
7. Turn on your computer: Once the battery and MagSafe power adapter are connected, press the power button to turn on your computer. The SMC reset process is now complete.
It’s important to note that resetting the SMC can resolve various hardware-related issues on your Mac, such as power management problems, battery charging issues, and unusual fan behavior. However, it should be used as a troubleshooting step only when necessary.
If you continue to experience issues after resetting the SMC, it may be worth considering additional troubleshooting steps or seeking professional assistance.
