Because the VJZ13A * series does not have a light indicator next to the power button, you cannot tell if the power button is turned on.  If you press the power button and nothing happens, wait a moment and then press Shift + Caps Lock.  If the Caps Lock light does not light up, it is possible that there is a power failure in the body.  Please try the following action.
