Sleep Problems - "Wake on Scan Offload"

[antpensi]

Hi all,

I've been having battery drain issues with one particular Early 2015 rMBP 13.3".

When the laptop is being used the battery seems to be fine, but when the lid is closed the drain is much too fast. On the worst occasion a 100% charge went to 52% overnight.

Running 'syslog | grep -i "Wake Reason"' in Terminal has revealed hundreds of 'Wake Reason's occurring when the computer should be asleep.

Any ideas of how to resolve this? Or anyone else have this problem?

Power nap is not allowed on battery power in my settings. Apps that were open before closing the lid were any of the following: Airmail, Messages, Chrome, Terminal, Sunrise Calendar, Wunderlist

I will include a snippet of the terminal output. There are chunks of the same stuff from the other hours of the night, it did not just occur from 03:01-04:00.


Terminal output:

There is a long thread in the Apple Discussion Forums here: https://discussions.apple.com/thread/7010693?start=180&tstart=0 with no apparent solution.

Until someone finds a solution, either turn off your wifi before sleeping the computer or shut it down for the night rather than sleeping it.

Okay, thanks.
