Do anybody have idea how to repair this?

I'm glad that Apple is enabling Power Nap for more models, but it would sure be awesome if they would enable it for MacBook Pros with third party SSDs. Probably a longshot, but many people are asking for it!

We recently noticed something weird with my wife's 13" MacBook Air (mid-2012) where every time it was woken from sleep, it would take 10 seconds or more for it to accept input from the Magic Mouse and keyboard. Thought something might have been wrong, and after some internet searches, I ran Software Update on a whim, and it turned up the SMC update 1.5. Saw that it fixes several sleep/wake issues, and sure enough, after installing it, the problem was gone!
