I've got a unit with no audio. I'd like to pull the rear cover and make sure its not something as simple as a loose connection between the main board and internal speakers. I'd like to know whether removing the rear cover is as simple as laying the unit flat on its face and removing all visible screws on the back. I don't want to do so and then find out that some of those screws were holding something to the inside of the rear cover, and should have been left in place. I'd also like to know whether there are any hidden screws or fasteners that are involved in removal of the cover. Thanks!
