- Using a computer case that includes an ATX 80W supply that runs from 5-35 VDC (I'm running it at 12).
- My case is an A-Open M-270 (aka Morex 2788)
- If I replace this DC/DC p/s with a real desktop ATX supply, the auto reboot feature WORKS!
- Running from the DC/DC p/s, if I cycle power before Windows loads, it does not re-boot.
So, this seems to be something to do with the timing of the electrical signals wrt to the power rails?
Is there a technical document on the timing of the "power up" signal that comes out of this board? Maybe its going active while my dc/dc power supply is still booting?
Thanks in advance, any thoughts appreciated.
