Resetting the System Management Controller

Today when I started up my laptop the time was set back before 1 Jan. 2008 and my Wifi connection couldn't be restored. The best way to deal with this is to reset the System Management Controller (SMC). For my Macbook Pro I have to follow the following steps:

  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 does not change states or temporarily turn-off when you reset the SMC.
