MacBook Air wouldn't go to sleep if I closed the lid or if I tried to make it sleep manually
my Mac Book Air (13-inch, 2015). It began yesterday when I realized that
it wouldn't go to sleep if I closed the lid or if I tried to make it
sleep manually. Today it escalated to blacking out randomly for 3-4
seconds before going back to normal. This happened continuously before
it shut down by itself. I did an SMC reset (Shift+Control+Option keys
and the Power button at the same time) and it still not working. sometimes it freezes and no movement of mouse.
