Q: Macbook goes to sleep randomly

I've had my new Macbook for about a month. I have noticed an issue where the screen goes to sleep and the trackpad has no feedback at random times. I do everything I can to try to get it to turn back on, but nothing I do seems to wake it back up. Then it suddenly just comes back to life after random periods of time. I read somewhere that it might be a thermal cutoff, but I am not doing processor intensive tasks when it happens. Anyone else have issues like this?

MacBook (Retina, 12-inch, Early 2015), OS X Yosemite (10.10.4)

    Is it happening while on battery or while plugged in? I am starting to wonder if it only happens while on battery power...and whether they sheer volume % of the entire body being made up of battery is causing electromagnetic interference with the sensors for the screen? For example, it is the same reason why people with heart-pace monitors, etc, cannot go through an area where there are electromagnetic waves, xrays, etc, it will interrupt the operation of sensitive electronics in which you have constant opening and shutting of sensor based mechanics...

    I also wonder of there could potentially be interference or faulty wiring from the force-click trackpad? It is made out of electromagnets...Screen Shot 2015-09-10 at 12.27.04 AM.png

    Hi Sam!

     

    Lol @ your reply. I'm glad it solved your issue as well.

     

    I could also reproduce the issue once I knew what to look for. There's only a small area, somewhere below the ALT / CTRL buttons, where I could get the Macbook too sleep once I put the magnet there. I attached an image to roughly show the area.

     

    It doens't matter if the Macbook is on power or on battery,

    macbook-12-interior-100572319-orig.pngYour diagram now gives me more impetus to believe that it is related to the Force-Touch electromagnetic bar which has its contacts grounded to the bottom shell OR the contact between the lower quadrant battery to the ribbon-connector to the other three or four remaining batteries and then into the motherboard. There could be a sort of EMF (electromagnetic force field) interaction in which some sort of safety short trips out and shuts off the force touchpad which then shuts off the screen or vice versa. Most likely vice versa. At this point, this has to be the best explanation and I think it could be a manufacturing flaw because I know mine occurs on the upper quadrant central battery area. So they may have not done a good job of shielding it off since they made all the materials so thin, along with the thin aluminum body or whatever metal it is. For example, many computers and cell phones have thin films in their plastic barrier that does not allow for that to happen. Maybe Apple, in making the design so sleek and thin, betted on leaving it out and it not being a problem, which for now seems to be the case unless you are near a magnet.

     

    Anyhow, see the attached picture and imaging where the keyboard and touchpad are placed on the other side and it makes sense.

    Hi Yes i sent a video to my local Apple Store of the MacBook shutting down and they pointed out to me that  I had the laptop sitting on top of the case and it is a snug case it has a magnetic strip in the lid and it thinks you are shutting the lid down hench the reason for it shutting down I think Snug should put a warning on the case that this could happen.

     

    Since I have found this out I do not put it on the case and I've never had a problem since

    Apparently it is the magnet being placed in that area that causes it - the mac responds to this as though the lid is being closed, as this is how that is recognised by every macbook. So it's not a problem or something that will do any harm, just annoying if you would rather have a case with a magnet closure...

    I have to agree; just an amazing answer to infuriating problem.  Suppose Snugg and Incase should provide a general warning, but I can only hope the message gets out.

    Thanks so much! I was tearing my hair out trying to figure out why my MacBook wouldn't wake from sleep/turn on. Then I stopped using my INCASE sleeve which has a magnet in it and now the issue has gone!

    I have the same issue. I bought a Macbook pro 13 last September. It sleeps randomly too and tilting or tapping the mac softly will turn the screen on again.

    Does you place it on the cover (with an internal magnate) when it has these symptoms?

    My sleeve has a magnet.... I might have placed it on top of the sleeve during those times that I was using it and it suddenly sleeps. But I don't understand why magnet might be the cause...

    wauw!

     

    I had same issue with my 12" macbook, it randomly freezed, or gave me the question mark and I had to reboot.

     

    Complained twice to Apple, twice(!!) they replaced the motherboard and once the screen .. €2000,- costs for Apple ..

    To find out its the magnet in my incase sleeve. Thats an expensive sleeve for Apple.

    I purchased a Incase canvas bag from the Apple retail store.

    It uses magnets to close the lids.

    Before using the Macbook Pro move the case away from the laptop.

     

    Yeah, pretty stupid design.
