2015 Air Won't Wake Up

[Xiaoluobo]

I have a new 2015 Macbook Air stock 13 inch I got about 4 months ago. Sometimes, and only sometimes, this thing will not wake from sleep for a LONG time. 15 minutes to an hour. Absolutely everything else works just fine.

Recently it took 5 days (yes five days) to wake from sleep. I had a brick with me for the holidays. Now that I'm finally home and have access to an Apple store to take it in, I cannot replicate this problem. For a whole day it has worked fine in and out of sleep like there was never an issue. If I cannot replicate the problem, I'm not sure about taking it in.

Anyone know whats going on here?

Start the "Concole" app and check all entries on the date/time you experienced this issue. You can scan the log library within the app utilizing the search box and keywords like "sleep", "wake" to focus on specific entries.
