Q: macbook air switches off and reboots with devices connected

Hi,

 

if I connect an apple trackpad and magic keyboard (just purchased) to my macbook air via bluetooth, after a varying short time (between 3 and 15 minutes) my macbook air just goes dead, screen is off, then after about a minute, it then boots up again. Tried different variations: keyboard and trackpad via usb cable: same result as via bluetooth. Just a DVI monitor via thunderbolt, same again. The DVI adaptor (just purchased) is also from apple. The phenomenon is 100% reproducible: that means I can't use my mac with any devices connected, except: USB sticks and disks work fine. Any ideas?

MacBook Air, OS X El Capitan (10.11.4), 13"

    These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

    Please launch the Console application in any one of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    In the Console window, select

              DIAGNOSTIC AND USAGE INFORMATION System Diagnostic Reports

    (not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select

              View Show Log List

    from the menu bar.

    There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.

    If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.

    In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)

    Please don’t post other kinds of diagnostic report.

    I know the report is long, maybe several hundred lines. Please post all of it anyway.

    When you post the report, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

    If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.

    Thanks Linc for the quick reply.

     

    ...checked the logs, there are no kernel panics seen.

     

    Running the HW diagnostics in the extended mode, the test does not finish: the macbook air shuts itself off right in the middle of the test (just like when using the apple peripherals).

     

    Running the diagnostics in the normal mode, I get an error: 4HDD/11/40000000: SATA(0,0).. which according to apple ( Mac notebooks: Apple Hardware Test may report "HDD" alert - Apple Support ) is erroneous... 

     

    I'm going to reset the SMC to see if that helps at all..  (Reset the System Management Controller (SMC) on your Mac - Apple Support).. won't get around to doing that now (00:01 CEST)..

     

    I'll post the results soon..

    You'd better make Genius Bar appointment to show them the circumstances you face with now.

    It's hardly believe that SSD trouble, though it would be...You should make backup data as soon as possible.

    SMC Reset results: didn't help the problem: when running HW diagnostics in extended mode the macbook air shuts off, then boots normally after a minute or two... 

     

    This mac has already had a Mainboard replaced, it's 3 years old.. I'm not going to put any more money into it..

     

    I'm off to buy a new pc and put linux on it.
