Q: Sleep light strange behaviour

Hello folks

I have little weird thing with my Macbook Pro 2012. Sleep indicator (light) switches off after a while, so I can't understand my mac is sleeping or not?

When I close it - everything is fine, but after a while - indicator stop blinking at all. I cannot catch the moment, because I don't sit around all the time, but if I leave it for whole night - I can surely discover that my mac doesn't blink. Any advice? I did SMC (with keys) reset and PRAM as well.

Little poo (could be) here - I changed SSD from MacBook 2010 to this model as is (without clean installiation. Could it be related with that? I guess this is software problem not hardware, because indicator light is working in general and blinking works also.

Thank you so much in advance

MacBook Pro, OS X Yosemite (10.10.4), null

    Hi KeyReel Fiddler,

     

    Welcome to the Apple Support Communities!

     

    I understand that the SIL (Sleep Indicator Light) stops blinking after being asleep for some time. Because you replaced the mechanical hard drive with a solid state drive, your Mac may be entering Standby Mode which may explain this behavior. For more information on Standby Mode, please read over the attached article below. 

     

    OS X: Saving energy with Sleep - Apple Support

     

    Standby Mode

    For Mac computers that are started from an solid-state drive, OS X includes a deep sleep mode known as Standby Mode. Mac computers manufactured in 2013 or later enter standby after one to three hours of regular sleep. A computer with a fully charged battery can remain in standby for up to thirty days without being plugged in to an AC power source.

    To wake your Mac from standby mode, press a key on the keyboard, or press its power button.

     

    Best regards

    " I changed SSD from MacBook 2010 to this model as is (without clean installiation. Could it be related with that?"

    Probably, the build numbers would most likely be different and that can cause weird problems.

    Here are the original build numbers:

    OS X versions and builds included with Mac computers - Apple Support

    So for instance:

    From the mid 2010 13" is          - "10D2125, 10F2108"

    and the non Retina 2012 13" is - "11D2515, 11E2617, 12A269, 13A603, 14C109"

    So quite different.

    That site specifically says:

    "Avoid trying to use a version or build of OS X that's earlier than the one that came with your Mac."


    It will make it easier to help you w/ your problem to know know more information about your computer; size, exact year built, RAM installed and OS you're running. Any history prior to your incident would also be helpful.

    Thank you! seems like truth. On Macbook white 2010 with the same SSD behaviour wasn't the same, just regular sleep.

    I didn't know about deep sleep.
