Recently, I noticed that my MacBook Pro retina 15" 2015 mid takes a quite long time to wake up from sleep.
Today, I realized that my machine didn't wake up but actually boots up. How did I know that? I've just typed
uptime command from a Terminal.app right after the screen shows up.
It says, for example,
1:25 up 3 mins, ...
That means, my machine has been running for only 3 minutes and it does not take time before sleep into account.
Then, only one explanation is possible. My machine has been shut down between sleep and wake. And I misunderstood its new boot as wake up
Another rationale is, Deepsleep (Standby mode) resets uptime counter. Huh...
Which do you think more legit?
