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)

When i turn on my Dell Inspiron 2400 Desktop Computer why won`t it start.


Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?

The power light is orange color and blinking when I switch on the computer. The computer is not powering up.


A steady or Amber blinking power button indicates a low voltage problem. 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.

Optiplex 755 blinking amber light, simple solution, I'm no IT professional.


If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.A power supply or system board failure has occurred. Try to isolate the problem by removing or disconnecting all cards, i.e. video, sound cards and disconnecting CD/DVD and hard drives.

Aux power led light is amber on dimension E521


I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.


Below are links and info I found from Dell's Website based on your model.

IN dell optiplex sx280 model system we are using in this amber power led blinking continuly yellow color because of this not able to boot the system. kindly give the solution for the same


Hi there!

A blinking amber/orange light on the power button of your Dell Optiplex means a hardware failure. If you know how to strip down your computer to basic component, then I suggest you turn on with only the motherboard, processor, memory and PSU. If you are not familiar with this, I suggest you bring the computer to a qualified technician.

Hope this helps

Turns the power button on and the power light keeps blinking in and out and the computer won;t come on


I would look into testing the laptop by taking out the battery and plugging in solely the charger, and try turning it on. If it doesn't work, it sounds like it can probably be an issue with the Motherboard or the RAM.

Is the blinking light an amber or green color? If amber, then it might be a RAM issue. If green, the power would be on, but the monitor might not be active/working.

The start green light on our dell dimension 9100 is blinking amber. I can turn off the machine and back on but machine won't boot up. Any ideas? span.jajahWrapper { font-size:1em; color:#B11196;...


If you see the boot screen, then it is a problem with your operating system (windows)
If you do not see the boot screen, then it is the power supply or the motherboard isn't working.
If it turns green but you never see the screen come on, then it may be the video or the monitor.
If it does go directly to blinking amber, it is probabbly the power supply. It should only take a little while for a computer person to plug in another power supply and test it.
You can actually take a power supply out of someone elses computer and plug it in (don't even have to mount it in the computer)
Plug in the motherboard plug(s) and the hard drive only, then attempt to start.
If it does work, it is your power supply, if not then it is your motherboard.

Tower problems


You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this


Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say

Blinking power button


It could also be because there is a problem with the display controller in the computer. Try to hook up another monitor to this computer and see if it comes up. If it does not work with another monitor, the computer will need servicing. If the display does come up, the Samsung monitor will need service. Good Luck
