Hi. I have a Mac Book and when i close the lid it goes into sleep right? Well i did that and put it in the incase sleeve and when i go to get it out it's all hot and wouldn't turn on. I left it out for a few mins and the fans turned off...so i tried to power on again and it did. when it powered on it said osx shut down unexpectedly. Did it overheat and turned itself off? Was it really in sleep? Will it overheat while it's in sleep inside of my incase sleeve?
