Random Shut Down
Check the voltage and LHR (Low Harmonic Resonance) jumper settings; make sure they are set correctly.
NOTE
There is one jumper for the voltage and one jumper for the LHR coil. Both jumpers should be installed when the computer is operating in the +110 V environment. If the jumpers are set correctly, refer to the “No Power” section.
