Hi everyone, I've had my rMBP for almost 10months now and initially I didn't have any problem (except IR cuz I have an LG display that apple won't replace because it's not "bad enough"). Last couple weeks, I've noticed that while I'm using the computer lightly browsing the web etc, the screen suddenly turns black then goes into the login screen. Does anyone else experience this and possibly know the cause? I want to take it to the Apple store but it's not something I can reproduce at will and it happened ~2-3 times the past week. Any insight or help would be appreciated. Thank you!
