   " Note:   
         There is also a keylock activated micro-switch on the adapter   
         guide assembly; it does not affect system power-up. "   
      
   So what about this micro-switch on the adapter guide assembly?   
      
      
        SYMPTOM:   
         The 9556 or 9557 will not power up.  There is no indication of   
         power from the fan, drives, power good LED, or keyboard lights.   
         There is no indication from the display that the system power   
         switch has been cycled.   
      
        PROBLEM ISOLATION AIDS:   
         Disconnect all external devices, printers, modems or switching   
         devices that are attached to the serial or parallel ports.   
         Remove the top cover and locate the Tamper-Evident Switches,   
         which are part of the Adapter Guide Assembly.  Attached to this   
         assembly, and extending through the front frame, is the blue   
         service slider.  As the slider is moved upward, it will contact   
         the metal actuator arms of two micro switches, allowing the   
         machine to be powered up with the top cover removed.   
         Both switches must activate for complete machine operation.   
         (The micro-switches produce a click that can be heard and   
          felt when activated.)   
      
        FIX:   
         If one or both switches fail to transfer, they must be   
         adjusted or replaced.  To adjust the micro-switch actuator   
         arm, remove the adapter guide (with switches) from the system.   
         Move the blue slider to the bottom of its travel and form   
         the actuator arms, so that the switches activate when the   
         slider is moved up 1/2 to 3/4 of its travel. Caution should be   
         used when reinstalling the top cover. An extension on the inside   
         of the top cover will contact the slider and move it to the   
         bottom of its travel, then contact the actuator arms and   
         activate the switches approximately 1/2 inch before the cover   
         fully seats.   
      
         The 9556/57 HMS will be updated to identify the Tamper-Evident   
         switches as a possible cause of "No Power" symptoms.   
      
         Note:   
         There is also a keylock activated micro-switch on the adapter   
         guide assembly; it does not affect system power-up.
