Have you tried turning the keyboard over and pressing the secret red button under the compartment marked simply as 'H1'. You must hold the right mouse button down at the same time and also suspend the left speaker about 7 inches above a polymo-hydromidus deliminator. Do not make contact with any fruit while you do this as the citric acids can cause a reaction. That should reset the computer. Do you need a diagram?
