I want to set my DSATX power supply to allow my PC to stay on standby for as long as the battery will permit. I have tried setting both the computer to hibernate and go to standby when the power button is pressed with no luck. I set the jumper to instant off on the DSATX, which would lead me to believe that it would be just like hitting the power button when the key is turned off. I have read through the instructions several times and read on here that people leave their car on standby all day with no issues. I cannot even get it to hibernate, what am I not setting right? I am not familiar with this so I hope this has not been covered I could not find my answer from searching. If I use a standard power supply and inverter it works fine, what’s the deal? Thanks in advance for any help.
