Question about Dell Dimension 8400 power supply ** FREE ** (D8400SATA300W24PINB) Power Supply
My Dell Dimension 8400 stopped powering up last year and was giving a blinking amber light. It stayed like this for about a month and then powered up one day!! It was fine all last year except for once when it did the same thing then powered up after one day. Last week, it did the same thing and is not powering up!! What is up? The problem seems so random.
p.s. I bought it from the states but I am using it overseas where the power is 240 not 110. Also, its power supply was damaged before due to a misconnection and was replaced by the original Dell Dimension 8400 power supply from Dell.
Any idea what is going on? Is this a common problem with the power supply of this model?
There are several different solutions for this as posted at this Forum.
1) A lot of people have just removed the Jumper for the CMOS and turned the Power back on and back off and replaced the jumper and/or removed the battery.
2) Several people have reseated the Memory and after booting back up it worked.
3) A few had to replace the Mother Board and CPU but in this instance they had to also replace the Case because the Dell case wasn't really fit for the heat of from the CPU.
4) I had the exact same problem and luckily replacing the Power Supply fixed this for me. I had to cut out the back of the Dell case for the toggle on/off switch but when I tested the old Power Supply it was only getting 5amps and this was causing the Amber/Orange/Yellow light to constantly flash.
I hope this helps!

1. Remove all USB devices such as printers, mp3 players etc etc.
2. Remove the power-cable and the battery
3. Press and hold the power button for 30 seconds
4. Put the power-cable back in but not the battery and none the USB devices.
5. Turn the computer on

It not a common problem. The problem that you are facing is is beacuse of faulty motherboard. The blinking amber is caused , becasue the motherboard is not able to distribute the power signal to the devices .
