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.

if you do not have time to correct your spelling - go be a artist or mime. Accuracy counts in everything - especially computer problem solving.

buying a new one / or bought a new one, is NOT a valuable solution to anyone.

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.

My GX520 was shut down as usual last night...I turned on this morning and I get nothing...just a little yellow/amber light blinking where it is normally green....help


Here is the info straight from Dell. looks like you have an internal power issue. You will most likely need to contact Dell directly for assistance, they are pretty good about giving support even if the system is no longer covered under warranty.

If the power light is blinking amber -
The computer is receiving electrical power, but an internal power problem might exist.
  • Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
  • Ensure that the processor power cable is securely connected to the system board.

Blinking amber light with green 4 light


If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Try, unplugging the power cable from the pc, and reinsert it, if this does not help try a differnt power outlet, if this dont help, open the computer, take the power Molex conector out of the mother board and try turning it on, if this dont help, take out the Memory modules and reseat them, if this dont work you may want to ring up dell support.

Hope this helps!

Computer will not turn on


  • Blinking Amber/yellow: Initial state of LED at power up.
    Indicates system has power, but the POWER_GOOD signal is not yet active.
    If the hard drive LED is off, it is probable that the power supply needs to be replaced.
    If the hard drive LED is on, it is probable that an onboard regulator or VRM has failed.

If the power light is blinking amber - The computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location (where power cord goes into unit).
Also try simply unplugging the unit from the wall outlet for a minute then plug it back in and boot it up.

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!
