can result in operational anomalies with the computer. Examples include not turning on, not
waking from sleep, not charging the battery, or not recognizing the AC Adapter, among others.
Don’t reset the SMC if the computer is unresponsive. An SMC reset should only be a last resort
in cases where a hardware failure of the power management system is suspected. Performing
an SMC reset returns the hardware, including NVRAM (Non-Volatile Random Access Memory),
to default settings and forces the computer to shut down.
For most situations, a restart is sufficient. If the computer has stopped responding, try each one
of these steps, one by one. Test in between steps to see if it has worked. If one step works, don’t
worry about the next, as you’re up and running! Only go on to reset the SMC if you’ve tried all
of the steps listed here and the computer still isn’t working.
1. Force Quit (Option-Command-Escape).
2. Restart (Control-Command-Power).
3. Force Shut Down (press the power button for 10 seconds).
Reset the SMC as follows only if the above steps did not resolve the situation.
To reset power management via the SMC chip:
1. If the computer is on, turn it off by choosing Shutdown from the Apple (apple) menu.
2. Connect the power adapter to the computer and to a working power source.
3. Important: Use the keys on the left side of the keyboard. On the built-in keyboard, press
Shift-Control-Option along with the power button once.
Note: When the LED on the MagSafe connector is orange, resetting the SMC will change it
to green for a few seconds, indicating that SMC was correctly reset.
4. Wait 5 seconds and press the power button to restart the computer. Note: If bottom case
is removed, you may alternately reset the SMC by disconnecting the power adapter and the
main battery, and holding the power button down for five seconds.
