   UNDETERMINED PROBLEM (SYSTEM DEAD)   
      
        Symptom:   
         Personal Computer System will not power up or powers down   
         immediately after being turned on. The cooling fan may start   
         to turn, and/or the power-good light may flicker then turn   
         off. The power supply will not stay on long enough to allow   
         voltage measurements.   
      
         Problem Determination:   
         -Systems with auto-switching power supplies should be plugged   
          directly into a wall receptacle, not into a power strip or   
          surge protector.   
         -Systems with switchable power supplies (115v/220v) must be set   
          to the correct voltage setting.   
         -The following switches may be checked with meter to verify   
          correct operation:   
              * Power switches that connect to the system board   
              * C-2 security (Cover Lock and Tamper-Evident) switches   
         |      (these two switches and related cables must be connected   
         |       and operating correctly before the system will power on)   
      
   --- SoupGate-Win32 v1.05   
    * Origin: you cannot sedate... all the things you hate (1:229/2)
