Thank you for writing to the community (DCF) ,I am Jennifer and I work for the Dell Social Media team .
In this case as per your troubleshooting when the power button is amber the system fails to post .And with the diagnostic leds show 1 and 3 codes it could possibly be a system board, power supply, or peripheral failure has occurred.
Do try these steps in the same sequence and provide the result ,
Power off computer, leaving the computer plugged in. Press and hold the power supply test button on the rear of the power supply unit. If the LED next to the switch illuminates, the problem may be with your system board.
If the LED next to the switch does not illuminate, disconnect all internal and external peripherals, and press and hold the power supply test button.If it illuminates, there could be a problem with a peripheral then remove the memory module from the system ,try powering on the system with just 1 memory module at a time and try it on all slots.Perform the same with all other memory modules.
If the LED still does not illuminate, remove the PSU connections from the system board, then press and hold the power supply button. If it illuminates, there could be a problem with the system board.
If the LED still does not illuminate, the problem is probably with the power supply .
If there are any more queries do reply to this community thread and we will be glad to assist you .
As I mentioned in my post, the only way to power off the system board is to unplug it.
As soon as the power is supplied to the computer the front power button light is flashing amber as well as the 1 and 3 codes. It does not shut off by pressing the button, so leaving the computer plugged in is not an option. When the PSU button is pressed the front panel light become green and the fans start to run, but as soon as the test button is released it goes back to flashing amber.
As for the power unit diagnostic I have performed that in the past, which is why I replaced the PSU and the system board. Both are new in the computer.
In this case I would confirm that the power supply unit and system board is working fine but the power is not transmitted to the peripheral devices.
Power off the system by unplugging it ,disconnect all the peripheral devices as such as memory modules ,hard drive ,cd drive ,then turn on the system with one component at a time .
I suspect the memory modules to have gone faulty ,but still will await your reply.Do send the service tag of the system via private message so that I can look into the details of the system .
Hi i would like to ask a favor,actually when i plug in my computer and press the power button a yellow light appears for a sec and turns off ,after i re plug my computer it starts normally but this problem is happening daily.i would be thankful if u could diagnose my problem
