Question about Dell Dimension 8400 power supply ** FREE ** (D8400SATA300W24PINB) Power Supply

2 Answers

My dell 8400 will not start up. power switch blinks amber.

Computer worked fine for 5 years. Yesterday, the computer would not start up. The power on/off switch just flashes amber at a rate of approx 1 flash per second.

Since I can't get my computer running, I am troubleshooting on a friend's computer now. If you could help me, would you please call me at 407-851-3982 and leave your phone number?

I can call you back so the longer troubleshooting conversation will be paid by me. If you do have any ideas, my next question would be, " how and where do I purchase spare parts....like power supply, etc....for my computer?

Thanks for any help you might be able to give me.

    I have the same problem I have to get a new power supply because I am pretty sure the one that was in there burned out...

    exactly same problem, and I'm not computer savvy to work on it, but short of money for repairs. Would attempt power supply if I knew which one to buy and where.

You need a new power supply. go to a store called microcenter or any place that sells computer parts and ask them for a "Sata Power supply 300 watt" it shouldn't cost you no more than 40 dollars

Dell dimension 8400 blinking amber light ethernet port


An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Since you replaced the power supply, my guess is that the motherboard has a problem.
Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Your power supply or motherboard has a problem. You can try getting a power supply on the internet ( $25 to $75) first. If no go then motherboard (about $100 to $200 ). The 8400 is about 6 years old which is the average lifespan of computers. One last thing you can try is removing the heatsink assembly and re-seating the processor. You have to clean the old thermal compound from the CPU chip and heat sink and reapply the compound (thermal paste). You might be better off buying a new computer from Walmart.

My 6 year old Dell Dimension 8400 quit working completely.


Depending on the symptoms, you may have different faults.

Flashing Amber power LED, normally power supply
AAGG Diag LEDs normally bad RAM
Solid Amber Power LED, bad motherboard or Expansion card connected to it.
If you need a motherboard a Precision Workstation 370 motherboard is essentially the same and is available, (8400 motherboards are scarce)

I turned on my Dell Dimension 4700 computer,but the amber light started to blink . I held the start up button for 5 seconds and the light went out. I tried to start it up again and got the same thing,...


Vaughn it sounds like the power supply is going bad, try another known good working power supply. If that doesn't work then the motherboard would need to be replaced. If the power supply isn't giving the correct voltages that could cause the computer not to turn on. If the motheboard isn't able to convert the voltages properly then the motherboard could be faulty.

Dell Dimension power problem


There are several different solutions for this as posted at this Forum.

http://www.tomshardware.com/forum/51352-2-dell-dimension-8400-wont-boot

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!

Have a yellow amber light blinking


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Computer Won't Power Up


If the blinking amber LED is on the computer itself and not the monitor, this is most likely a power supply issue. First thing to try would be replace the power supply. If the blinking led is on the monitor, it probably has bad capacitors and needs to be replaced. (or repaired)
