shuts down during sleep mode
after el capitan update, my macbook air shuts down in sleep mode every single time. it's ok during screen saver mode only.
I have to power it back on, and the bars starts up and prompts to log in, (it doesn't make the typical mac music sound when I power it up from this though)... then it says it shut down because of an error.
MacBook Air, OS X El Capitan (10.11.1), null
