Simply way to get something apart when it doesn't want to.
This sounds a little too simple to mention but it does work when nothing else does. Occasionally I have a printer that I can't get the top case off for some unknown thing holding it together so what do I do? I take it out to my paved driveway and toss it as high as I can in the air. I can guarantee you something is going to come off it when it hits. Especially by the second and third landing. It does scatter stuff everywhere but it is fun. A little safer too than hitting it with a big hammer which by the way is my second choice of getting printers with stuck cases apart. Use large hammer (and safety glasses and gloves).
