Is it one of those stupid bookcase designs Dell is so fond of? If so, there will be a black button on the tpo and another on the bottom. Tip it on its side and press both then pry the case open as you would a book, only with a lot more force. Ubrales March 4, 2012 8:29:53 PM ^ Yes! Like a suitcase! Open the case outside or in the garage because the computer will be full of dust and lint! Can't find your answer ? Ask !
