What is the EC.DarkPME?

    If any wired peripherals are connected, disconnect them and test.

  • 2. Re: Wake reason: EC.DarkPME (Maintenance)
    DmitrySPB Level 1 Level 1 (0 points)

    No wired peripherials connected

    Please read this whole message before doing anything.

    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

    The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.

     

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    • Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    • When you see the gray Apple logo, release the shift key.
    • If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.

     

    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Test while in safe mode. Same problem?

     

    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    I was having this problem today, it was happening because my Razer Naga Wireless Mouse was fully charged and set to charge on it's docking station. After setting it back to wireless the error stopped occurring.

    thanks for advise, but wakes are still there (in safe mode). Power decreased from 77 to 70% in "sleep mode"

    What Bluetooth devices are in use?

  • 7. Re: Wake reason: EC.DarkPME (Maintenance)

    No BT devices. BT switched off

    This is either a corrupt installation of OS X, a hardware fault, or some kind of obscure bug. I suggest you reinstall OS X after backing up all data. If there's no change, take the machine in for warranty service.

    Thanks! I'll try to reinstall it

    New information.

     

    I reinstall Mac oc x Lion with formatting hard disk. I didn't apply update fo macbook 2.0 yet.

    Now my mac wakes every hour and then go to sleep after 10 minutes. Battery discharge decreased.

    Update info

     

    At http://www.opensource.apple.com/source/PowerManagement/PowerManagement-271.41/pm configd/PMAssertions.c I found this:

     

    /* _DarkWakeHandleNetworkWake runs when PM enters dark wake via network packet.
    * It creates a temporary assertion that keeps the system awake hopefully long enough
    * for a remote client to connect, and for the server to create an assertion
    * keeping the system awak.
    */

     

    So I think DarkPME is a network related reason. Maybe near me in the building there is somebody sent packets to wake any Apple devices. In me energy settings wake over lan was disabled.

    You can test your theory by disconnecting from the network.

    Hello, I am having the same exact issue. When MBA is on battery, power drains from 25% to 30% overnight. It started about 1 month ago. I have called Support, and they have no answers. Last thing was they asked to do was to capture data and it's with Engineering at this point.

     

    The lines below repeat throughout the night. Any additional ideas as to what to do? I have a 2012 MBA, and it's about 6 months old.

    Hi!

    All that I collected:

    1. This happens only on MacBook Air 2012 with 10.8.2. My girlfriend's MBA 2011 sleeps ok.

    2. MBA 2012 with 10.8.2 and update 2.0 wakes every 5 minutes. W/o update - every 1 hour

    3. Yesterday I updated my MBA 2012 with 10.8.3 for developers - this night my MBA slept ok (100% battery not changed). Today I also will test this
