Wake reason: EC.DarkPME (Maintenance)

My macbook air 2012 wakes up when lid closed. Power Nap switched off, wake on lan and bluetooth disabled. SMC alreedy reseted. Power config files were deleted and rebooted. In console i found this:

Dear friends!

Finally I found a solution to my question!!!

After some firmware modification Apple realized two ways of MB sleep: 1) standby, 2) autopoweroff. I have old MB air where command pmset -g prints only parameters related to standby regime and that MB sleeps very well. In my MB Air mid 2012 pmset - g prints both - standby and autopoweroff - and they all were enabled. Now I set autopoweroff to 0 and my MB goes to hibernate with pleasure and sleeps all days and nights 🙂 No battery discharge at all !!! Now when I opening lid - MB thinks during 1-2 sec and then I see my Desktop.

Here cutted power log:

Aug 11 10:59:48 MBA.local powerd[16] <Notice>: Clamshell Sleep: Using BATT (Charge:76%)

Aug 11 10:59:48 MBA.local powerd[16] <Notice>: Clients requested wake events: None

Aug 11 11:09:52 MBA.local powerd[16] <Notice>: DarkWake [CDN] due to EC.SleepTimer/SleepTimer: Using BATT (Charge:76%)

Aug 11 11:09:52 MBA.local powerd[16] <Notice>: hibmode=0 standbydelay=600

Aug 11 11:09:52 MBA.local powerd[16] <Notice>: Maintenance Sleep: Using BATT (Charge:76%)

Aug 11 11:09:52 MBA.local powerd[16] <Notice>: Clients requested wake events: None

Aug 11 21:40:28 MBA.local powerd[16] <Notice>: Wake from Standby [CDNVA] due to EC.LidOpen/Lid Open: Using BATT (Charge:78%)

Aug 11 21:40:28 MBA.local powerd[16] <Notice>: hibmode=0 standbydelay=600

Here is my pmset settings (on battery power):

pmset -g

Active Profiles:

Battery Power -1*

AC Power -1

Currently in use:

standbydelay 600

standby 1

halfdim 1

hibernatefile /var/vm/sleepimage

darkwakes 0

disksleep 10

sleep 10

autopoweroffdelay 14400

hibernatemode 0

autopoweroff 0

ttyskeepawake 1

displaysleep 2

acwake 0

lidwake 1

I tested with hibernatemode 0 - it means keep image in memory. MB also sleeps well with mode 3 - combined regime.

Good luck with yours!!!

Update didn't solve the problem - at 9 am wakes continued every 10 minutes 😟

Tommorow will take macbook to my work to make test of environment - maybe somebody's apple device wakes my

Jan 10, 2013 10:35 AM in response to DmitrySPB

In some other threads, I read that it's happening to MacBook Pros as well. and some said it had to do with the latest Firmware Update 2.0.

Today I will try turning off WiFi and see if that helps. I was contemplating doing a reinstall but based on your feedback, it doesn't seem to help much.

At work my MBA also wake up every 4 minutes with DarkPME until 4 hours expired. Then it hibernated and didnt wake up until I open lid. So it wasn't another device that could wake my macbook.

Now I set autopoweroffdelay parameter from 14400 to 3600 seconds with

pmset -a autopoweroffdelay 3600

Will see results...

Jan 11, 2013 6:37 AM in response to Christian Calderon

Update: Last night I turned off WiFI, and the EC.DarkPME (Maintenence) activity still happened every 5 min from1:50AM until I opened the lid at 9:33AM

Battery was drained 15%

I already applied that one 2 days ago. Still no change

Jan 16, 2013 5:45 AM in response to DmitrySPB

Have the same Wake reason: EC.DarkPME. In reviewing the full log, see the same calls to devices as the other posters, and I'd tried the same litany of disabling things short of clean reinstall. Also see something that I suppose might be hunting for an input device: tv.sage.sagetv running repeatedly. Don't have SageTV installed now, but might've tried out a demo once upon a time on the machine that I migrated from to my current MacBookPro. Could be an artifact or perhaps embedded in another video related program. Haven't been able to identify it using spotlight, but maybe there's a better way to search or investigate with terminal.

Jan 16, 2013 10:21 AM in response to tangonerd

I have been in contact with Apple Support since December 24. I have captured data and sent to them.

Yesterday they made me uninstall Dropbox and MintQuickView. Of course, it didn't help.

According to Engineering, the EC.DarkPME wake reason does not seem to be a concern? I have not reviewed the full log. as I am not sure I'd understand it all.

I have exactly the same problem with my air 2012. The EC.DarkPME (Maintenance) is running every 3 minutes. I tried with a fresh mauntain lion installation (10.8.2) but didn't help me. 😟

Did somebody tryed the darkwake=no in file com.apple.Boot.plis like it was describribed in https://discussions.apple.com/thread/3735289?answerId=17653828022#17653828022. In http://www.tonymacx86.com/general-help/69714-important-darkwake-0-flag-can-break -auto-sleep-10-8-1-a.html was discovered that darkwake=0 is no longer works in 10.8.1. Reboot required

With this settings on my system darkwakes were during 2 hours, then it succesfully slept

Hi!

In Finder - do you see other computers in shared places? I see 3 computers, two of them I've connected as guest. Maybe this is the reason of wakes?

New information:

it is not due to neighboring computers. I switched off my wifi router and my MBA still wake up.

I reseted SMC and NVRAM - no effect

I set wakeup scheduller at 7am every day - MBA still wakes every 5 minutes

Summarizing, I think the problem is in macbook's firmware, not in OS. Now I have to power off MBA to save energy

Feb 3, 2013 9:39 AM in response to DmitrySPB

Update:

Per my discussion with Apple Support, we created a new partition and reinstall the OS. I tested overnight without any software updates, batttery drained 3% in 9 hours.

Then I installed Firmware update 2.0; I tested it overnight, and battery drained 31% in same 9 hours. I think it's pretty clear, there is something wrong in that Firmware update.

I have sent those results to Apple Support but have not heard from them yet.
