Q: SMC reset isn't working + fan working too much on MacBook Air 2014

Hello

My fan is working too much

When I open my MacBook Air running OS X 10.10.4 it's normal, when we reach to the point were we see the apple logo and my username + password it starts running again

I tried to use shift+option+cmd and power button for at least 14 to 18 seconds but it doesn't work

should I try to hold for 25 seconds? is it normal? what should I do? install the new OS X El Captain?

thanks?

 

 

+edit: I noticed that only the left part of the keybord gets hot and my macbook starts getting a lil bit slow on internet normal?

MacBook Air, OS X Yosemite (10.10.4), null

    Based on what you indicate in your initial post, you did not perform the SMC reset correctly:

     

    https://support.apple.com/en-us/HT201295

     

    Read carefully:  SHIFT + CONTROL + OPTION + POWER.  (COMMAND is not used).

     

    Run an Apple Hardware Test and see if that provides a clue:

     

    https://support.apple.com/en-us/HT201257

     

    Note that an error free AHT is not conclusive.

     

    Ciao.

    Thank you for responding!

    And sorry for making a mistake, I typed Command but I meant to say Control.

    That said, I wanted to try it again but nothing worked... I performed it again, pressing on the 4 buttons nothing on the screen...

    So I did what you told me, I ran a apple hardware test but it said that no issues found!

    I'm sad.

    Install a temperature/fan speed monitoring application.

     

    Open Activity Monitor to ALL PROCESSES and set CPU to display values from high to low.

     

    When you think the fan is 'working too much' take images of both and post them for review.

     

    Ciao.

    Thanks!

    quick update: the fan is doing a lot of noise even when i start my macbook

    but the problem with the hot keybord is gone... seems a little bit odd??

    A properly operating MBP should not have a noisy fan when when starting and when running simple non-intensive applications.  You may have a faulty fan or one that requires cleaning.  In addition, there also may be a sensor problem.

    macbook air*

    It's not faulty... if it was faulty the hardware test could have told me no?

    The only time that I am willing to accept the results of a Apple Hardware Test is when it develops an error.  When it comes back error free, all It says to me is that no errors were found, not that there are no errors.

    ohhhh i see!

    I'm going to try to clean the fan with my vacuum (when the mba is shut down + cold vacuum and lightly cleaning it) do u think it's a good idea?

    Personally I would remove the fan for cleaning.  But that approach may not be for everyone.
