I recently purchased a 13" late 2012 rMBP refurbished from Apple. It's been trouble free for the past month and I've been running Mavericks on it since the first day I got it. Last night I was just browsing the internet on the couch and when I was done I closed out Chrome and shut the lid to put it to sleep like I always do. The battery was at about 50% so I plugged it in to charge overnight. When I woke up this morning and picked it up I noticed it was extremely hot. I opened the lid and nothing happened at all, so I tried the power button and nothing happened. I had to hold the option key and the power key for it to start and when OSX booted, it said it did not shut down correctly. So far it seems like it's working ok, but it was very scary and I thought it had completely died on me. Has anyone ever experienced anything like that before?
