At night, I do not turn off my MBA using the power button, I just close the lid and open it in the morning. Sometimes, once every few weeks, I open the lid and find that it has turned off itself at night. This happens both when running on battery power and when running on mains power. Based on the battery status, I see that it turns off at 6 am, then at 9 am. It is unclear why it does this and how to prevent it. I have not noticed this before.
Of course, this is not a big problem, but it is still unpleasant when you open the lid in the morning and all your windows start loading and changing their data.
