The System Management Controller (SMC) is a vital component in a MacBook Pro that controls power management, battery charging, thermal management, and more. It ensures the smooth operation of your MacBook Pro. If the SMC encounters issues or becomes unresponsive, problems like a frozen display or unresponsive keyboard can occur. Resetting the SMC can often resolve these issues and restore optimal performance. Here’s a step-by-step guide to resetting the SMC on a MacBook Pro: 1. Shut down your MacBook Pro. 2. Connect the power adapter. 3. Press and hold the Shift, Control, Option, and Power buttons simultaneously for about 10 seconds. 4. Release the keys. 5. Power on your MacBook Pro. After resetting the SMC, you may need to readjust some settings. If problems persist, contact Apple Support or an authorized service provider.
Whether your issue is slowed performance or a battery that won’t charge, resetting the System Management Controller (SMC) on a MacBook Pro can help. An SMC reset can address issues related to hardware, such as unexpected restarting or dimming of the display, but it can also fix connection issues with other connected devices. Here’s a guide on how to reset the SMC on a MacBook Pro.
Step 1: Shut down the laptop.
Before you undertake any serious troubleshooting, you should shut down your MacBook Pro. Make sure it’s completely shut down — you don’t want to try resetting an SMC while your laptop is in Sleep mode. Press and hold the power button for ten seconds to force a complete shutdown.
Step 2: Unplug AC and battery.
Before fixing an SMC issue with a reset, you must unplug the AC adapter and the battery from your MacBook Pro. Once both are disconnected, press and hold down the power button for five seconds.
Step 3: Plug in the AC and press the power button.
With the power disconnected, press and hold down the power button for another five seconds. This allows the SMC to reset.
Step 4: Reconnect the battery.
After the SMC reset is complete, plug the battery connector back in to the laptop. Then press the power button once more without holding it. Wait for the Mac to boot up.
Step 5: Test your laptop.
As soon as the Mac starts booting up, the SMC reset will be complete. Test out your laptop to make sure all of the issues you were having before the reset have been fixed.
If your MacBook Pro is still having the same or similar problems, you may need to take your laptop for repair. A technician can help you determine if the SMC reset is enough or if you need more extensive repairs.
Resetting the SMC on a MacBook Pro is a great first step to try and fix any hardware or connection issues. Follow the steps outlined here for a successful SMC reset.
