March 16, 2015 by @HKw@! | Filed under Mac OS X, MacBook Pro.

I have updated My MacBook Pro to Mac OS X Mavericks.  Initially it working fine. After few week, i noticed that the WiFi wouldn’t work. When i clicked the wireless icon, it show the error Wi-Fi : No hardware installed.

Wi-fi No Hardware installed

To solve this problem, i tried to reset the System Management Controller (SMC) by removing the battery. Below are the steps:-

  1. Shut down the computer.
  2. Disconnect the MagSafe power adapter from the computer, if it’s connected.
  3. Remove the battery.
  4. Press and hold the power button for 5 seconds.
  5. Release the power button.
  6. Reconnect the battery and MagSafe power adapter.
  7. Press the power button to turn on the computer.

tested the bluetooth works perfectly.

In most of cases, you cannot remove the battery (it will Void Warranty), you can try to use following steps to reset the System Management Controller (SMC)

  1. Shut down the computer.
  2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
  3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
  4. Release all the keys and the power button at the same time.
  5. Press the power button to turn on the computer.
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

After reset the System Management Controller (SMC), i tried to powers on my MacBook, the wireless is back to normal. 🙂
