hey guys, so i closed my macbook and put it in my incase sleeve and into my backpack. normally as soon as i close it, it goes into sleep mode. this time i took my computer out of the incase sleeve and its HOT AS HELL. i open it and it doesnt turn on. i keep holding the on off button and it doesnt reset. i leave it be for a little while, then press the on button...it turns on. my computer seems fine now, but should i be worried about the fact that it may have overheated?
