Different models have their power buttons located in different places. The More Recent vintage iMacs have them on the back of the screen in the Lower Left (as viewed from the front)

Mac Mini's depending on vintage, also on back but could be on the left or right corners.

Mac Pro's right on the front about midway down.

Laptops tend to be on top of the keyboard portion of the shell back Right hand corner (really vintage models, some were on the back)

The power button is on the back of the LCD screen in the lower left hand corner. You should power down by clicking on the Apple Logo in the upper left hand front corner and choose "Shut Down". If your screen freezes, you can power off by pushing the power button and holding it.

MacBook Pro is slow when disconnected with electric charging.


First step would be to Reset Your Mac's SMC
The method for resetting your Mac's SMC depends on the type of Mac you have. All SMC reset instructions require shutting down your Mac first. If your Mac fails to shut down, try pressing and holding the power button until the Mac shuts down, which usually takes 10 seconds or so.

Mac portables with user-removable batteries (MacBook and most MacBook Pros):

1.Shut down your Mac.
2.Disconnect your Mac portable from its MagSafe connector.
3.Remove the battery.
4.Press and hold the power button for at least 5 seconds.
5.Release the power button.
6.Re-install the battery.
7.Reconnect the MagSafe connector.
8.Turn your Mac on.
Mac portables with non-user-removable batteries (MacBook Air and some late 2009 MacBook Pro models):

1.Shut down your Mac.
2.Connect the MagSafe power adapter to your Mac and to a power outlet.
3.On the built-in keyboard (this will not work from an external keyboard), simultaneously press and hold the left shift, control, and option keys while you press the power button. Release all keys at the same time.
4.Press the power button to start your Mac.

Mac desktops (Mac Pro, iMac, Mac mini):

1.Shut down your Mac.
2.Unplug your Mac's power cord.
3.Press and hold the Mac's power button for 15 seconds.
4.Release the power button.
5.Reconnect your Mac's power cord.
6.Wait five seconds.
7.Start your Mac by pressing the power button.

Alternative SMC reset for Mac Pro:

If you have a Mac Pro that isn't responding to the normal SMC reset as described above, you can force a manual SMC reset by using the SMC reset button located on the Mac Pro's motherboard.

1.Shut down your Mac.
2.Unplug the Mac's power cord.
3.Open the Mac Pro's side access panel.
4.Just below the Drive 4 sled and adjacent to the top PCI-e slot is a small button labeled SMC. Press and hold this button for 10 seconds.
5.Close the Mac Pro's side door.
6.Reconnect your Mac's power cord.
7.Wait five seconds.
8.Start your Mac by pressing the power button.
Now that you have reset the SMC on your Mac, it should be back to operating as you expect. If the SMC reset didn't fix your problems, you can try combining it with a PRAM reset. Although the PRAM works differently than the SMC, it can, depending on your Mac model, store a few bits of information that the SMC uses.

The easiest way to resolve this problem should be to reset the SMC - System Management Controller - which deals with how power is distributed to various parts of your Mac, including the fans.

How to reset it depends on what kind of Mac you have, though.

For 'desktop' Macs, including iMac and Mac Pro:

  1. Shut down the computer.
  2. Unplug the computer's power cord.
  3. Wait fifteen seconds.
  4. Attach the computer's power cord.
  5. Wait five seconds, then press the power button to turn on the computer.


If you have a portable with a battery you cannot remove:
  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.



If you have a portable with a battery you can remove:
  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.
That should take care of the problem. Good luck!

Hello and thank your contacting Fixya Support, I will be glad to assist you.

-PMU RESET-
The Power Manager is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls back lighting, hard disk spin down, sleep and wake, some charging aspects, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Disconnect all the connections going into the Mac except for the Power cord.
• Once all connections have been disconnected, remove the power cord from the Mac.
• Wait 20 seconds.
• Reconnect the keyboard, mouse and power cord back into the computer.
• Press the Power button to restart the Mac computer.

Try this procedure and if it works, great, If it does not, just reply back to this post
and let me know.

Regards,

-Terry
