Please help with Opus auto power problem
I just hooked up the PC and everything in my car, there are still lots of issues need to be addressed, but the basic power problem is bothering me and I can't seem to find an answer so was hoping someone can point me to the right direction.
I am using Opus 320W to driver a Dell 4550 MB, IGN signal is connected from cigarette lighter 12V+. I measured voltage on the power wire from PC end it's 12.53V, same as what I measured from battery. IGN voltage at PC end is 11.85V so everything looks fine.
When key is in OFF position:
- Opus blinks slowly
Turn key to the ON position:
- Opus blinks faster
- PC fan and hard drive spins for a second then shuts down
If I short the two pins from MB where I plugged in the power control cable (while they are still connected) then PC boots up fine, everything works from there.
Turn the key OFF again:
- PC shuts down instead of hibernating, Opus back to steady blink.
I checked the BIOS setting the power management is set to S3, but couldn't find out why it does not power on the PC. If anyone has any ideas please help...
