Does your Macbook fan sound like it's about to melt down your computer? Have you tried putting your laptop to sleep and/or shutting it off in hopes that it magically resets itself and the fan issue disappears?? 

Well if that sounds like you, you've come to the right blog post, I too, ran into this issue and without having to bring it in to Apple's Genius Bar...I have fixed the issue!

I'm a genius! Actually, I'm really not, the Apple technicians are, I'm just really good at following directions :)






Just like any other day, I closed my Macbook Air and plugged it into its power source. Upon returning and flipping the top open an hour later, the fan started to whir like an angry beast and would not turn off! I put my Macbook to sleep, and while the screen went to black, the fan kept whirring and whirring, making it sound like it was going to overheat my Macbook and break it! In the top right corner of my screen, my battery indicator had also disappeared, how odd. Let's turn it off! Surely it will magically reset itself and everything will return to normal!

Not so, as I shut down my Macbook, the fan also shut down, but the moment I turned it back on, the angry fan came back. I really didn't want to take this beast into a store...because I am lazy, and also because it was the afternoon and my kiddos were taking their naps, and also because I am lazy and didn't want to leave the house. 

I popped online to the Apple support forums and found out that you can run a quick diagnostic test and your Macbook would let you know if it was having any issues, couldn't hurt!


To run diagnostics on your Mac:
  1. Power down computer
  2. Turn on power and immediately press and hold the "D" button
  3. Follow prompts to run diagnostics
It only took a few minutes to run the diagnostics, and then this screen appeared giving me 2 reference codes. PPT001 for the battery, and PFM001 for the System Management Controller (SMC).


I hopped on to the Apple support site and decided to chat with an Apple support person. I told them my issue, gave them the reference codes and they said that I probably just need to reset the SMC. They provided me with this set of instructions and said if that doesn't work, then I would need to bring my computer in to the genius bar.

  1. Shut down the computer.
  2. Plug in the charger to a power source, connecting it to your Mac if it is not already connected.
  3. On the built-in keyboard, press the (left side) Shift-Control-Option (also labeled Alt) keys and the power button at the same time.
  4. Release all the keys and power button at the same time.
  5. Press the power button to turn on the computer.


Huzzah! It worked! The light on my charger went from nothing, to green, to orange! I powered my Mac back on and the battery indicator had magically reappeared, and the angry fan sound was gone! My computer was happy, and more importantly, I was happy...and I didn't even have to leave the house :)

Let me know in the comments below if you ran into this same issue and if the button combination fixed your Mac. 


Happy computing!
