Everytime when I turn on the machine, on the screen it states "close upper cover", of course I have already closed the upper cover. But the machine stay like this withou any action and even though I try any other buttons, it just have no any reaction at all. I cannot even turn off the machine by the Power button. I have to cut off the cable and power on again..... and it come all the same situation !
Is anybody tell me how to solve the problems ?
