I have an ATX PC hooked up to a relay and a 140W inverter in my car. When I turn the key on the ignition, the radio comes on. I then go to press the momentary button to power up my computer, but it will not start. Upon looking at the inverter, I see that the light on it is flashing instead of being constant. Now, if I cycle the on/off switch on the computer's power supply, the inverter light suddenly becomes constant now, and I power the machine up again using the momentary button. So my question is, what is the problem here and what is the easiest way to solve it. I had previously used this inverter with an AT style computer (but not with a relay) and it worked perfectly starting the machine up.
No announcement yet.
