13" mid-2013 MBA going back to sleep right after waking up.
My 13" mid-2013 MBA goes right back to sleep a couple of seconds after waking up, even if I start working. After waking up and logging in for a second time, it keeps running normal. I've seen several people reporting this issue but none have reported a solution. Any ideas?
