comics_addict Level 1 Level 1 (40 points)

I recently upgraded my Macbook Pro mid-2012 13" Intel Core i5 laptop to a SSD. I purchased a OWC Mercury Electra 6G model for this machine. Everything seems to run fine except when I leave my notebook with the lid closed to induce sleep mode and its been running off of battery power for well over an hour. This issue occurs : https://www.dropbox.com/s/rghjwckw07m59ea/IMG_0866.MOV Have anyone who have done a similar upgrade to this model experiencenced this specific isue ? Thanks.

    Watched the video, nothing seemed wrong unless I am missing something obvious...what exactly is the problem?

    watched the video, there is nothing going on in it,... except a nice looking macbook waking up from a snooze.

    Sorry I seem to have not explain the issue very well. You see on my personal experience putting my MBP to sleep, with it's stock HDD,  even with safe sleep enabled by default it never gets to such a low power state that as you can hear on the video the optical drive chimes as if it was booting up. Also the blinking light besides the IR receiver is not flashing as if it was turn off. Have you heard or seen anything like this after a SSD upgrade ?

    Open terminal.app, enter the following bolded command. What value is returned? 3 should be the default for your machine:

     

    pmset -g | grep hibernatemode

     

     

     

     

     

     

         hibernatemode = 0 (binary 0000) by default on supported desktops. The system will not back memory up to persistent storage. The system must wake from the contents of memory: the system will lose context on power loss. This is, historically, plain old sleep.

     

     

    hibernatemode = 3 (binary 0011) by default on supported portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from disk image.

     

      hibernatemode = 25 (binary 0001 1001) is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.

    hibernatemode = 3 came out. :/

    that sound comes when the macbook wake up from sleep, the sound of the optical drive.

     

    If that so, consider that normal.

     

     

    Mac notebooks: Noise when powering on or waking from sleep is normal

    Symptoms

    When powering on or waking from sleep, some components in your notebook may make unfamiliar noises.

    Resolution

    For instance, when optical (even if there is no disc inserted) and hard drives first receive power and make themselves ready for use a whirring or buzzing sound may be present for a few seconds. Additionally, fans in the computer may start off at full speed, but will taper off as the computer continues to start up or finish waking from sleep

    I am pretty sure you can disable hibernation alltogether for SSD's...it seems to be unnecessarry with a SSD. To do so,

     

    sudo pmset -a hibernatemode 0

     

     

    Do so at your own risk, as I am not positive about this. This would stop the behavior you describe.

  • nbar Level 5 Level 5 (6,980 points)

    This refers to only to an optical drive. A SSD is not an optical drive - there is no disk. This would not apply.

     

     

     

    Update: nevermind, I see what you are saying now --coming from the optical drive. There is still an optical drive, obviously, even with HDD replaced with SSD. Apologies.

  • PlotinusVeritas Level 6 Level 6 (14,710 points)

    The Optical drive is the only noise in the video. 

     

    the laser tray in the optical superdrive is making a resetting noise.

     

    Yes, I know what a SSD is, Ive got nearly 100 HD in the house, and half dozen Sandisk and Samsung SSD

     

     

     

    ~~~Update: nevermind,    no worries, I make plenty of those "Dohh" moments myself, hey its 12:30 for both of us

    Sorry I do not seem to get you. The sound indeed is coming from the optical drive like PlotinusVeritas confirmed to me. Any chance you might provide the original article Plotinus ? But all this doesn't answer the fact that when this happens the the blinking light is not on as if it were turn off. All this happens as if it went into safe sleep/hibernation but the the thing is is that the battery juice is near or at full capacity so why is this happening ? Also tested with Windows 8 running on bootcamp and it doesn't seem to be able to reproduce the issue.

  • nbar Level 5 Level 5 (6,980 points)

    See my update. I thought Plotinus was referring to your dedicated storage unit. I misread. He is right. The sound is from your 'superdrive,' not your SSD. It is from some apple support article which he will post in his response.

    Over here it's also 12:30 I just wanted to confirm that this SSD was simply switched from the stock HDD on the main bay for storage. Since my machine still has the limited warranty I have not dared tried to install a optibay on it yet.

    Don't worry I only saw your update after I submitted my response to your original post.

  • PlotinusVeritas Level 6 Level 6 (14,710 points)

    Even though I have a macbook (new) 10 feet from me, I recall the white blinking IR light doesnt flash unless you have it plugged in.     You arent voiding the warranty by installing a SSD. 

     

     

    As for the Optibay expansion, I wouldnt but thats just me. Ive done it twice for other people, but if you ever resell it, almost nobody will want that. Also its rather a low key event to pack around a 2TB 2.5" USB HD, now running $120. However that is a subjective choice. I CAN tell you however that the SATA cable used on that expansion is less than ideal and seen more than a few fail miserable.  Reliable SATA connectors, oddly enough, are extremely rare on the commercial market in add-on kits, or expasion enclosures.

     

    Since your mac is booting run, running fine, your superdrive noise of the laser-tray reset is normal. I wouldnt worry one bit about the IR light.

     

     

    *Remember now that you have a SSD,.... to adamantly back it up (always have 2 backups)...... When a SSD dies, it doesnt "fall" like a HD does, with bumps and bruises, ......SSD generally "jump off the cliff"  with no recovery possible... i.e. data is genuinely LOST
