M400S Will Not Power Up

Post by JAK Precision »

I have a Centroid M400S Controller that will not power up. I changed the CPU battery on the mother board but still no luck. I have a hand written procedure from the last time I did this to short the number 3-4 pins on the power cable from the power supply to the mother board to start, Press Delete to enter setup, then enter Power Management to turn AC Back Function to ON. Pressing the Delete button is not starting the S/U mode. Suggestions needed!

You need your motherboard type.
