I’ve got an Octane with the Lucent PSU. Plugging in the cord gives me a high pitched whine which I believe is the fan that’s gone bad. The fan does not spin. I can’t find the exact pinout of the 24 pin connector but some poking and prodding seems to give me valid voltages. However pressing the button with the cover removed gives me no signs of life. I reseated everything I could. Looking for ideas. Thanks!
