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

I my projector is new one used for 4 hrs, when i try to turn it on it just has a blinking green light. Please help Solve It! .


The blinking green light means the unit is either Powering On (Warming Up) or Powering Off (Cooling Down).

Powering On the Projector
1. Remove the lens cap.
2. Securely connect the power cord and signal cable. When connected, the ON/STANDBY LED will turn Amber.
3. Turn on the lamp by pressing " " button either on the top of the projector or on the remote. The ON/STANDBY LED will now turn Green. The startup screen will display in approximately 10 seconds. The first time you use the projector, you can select your preferred language from quick menu after the startup screen displays.
4. Turn on and connect the source that you want to display on the screen (computer, notebook, video player, etc). The projector will detect the source automatically. If not, push menu button and go to "SETUP". Make sure that the "Source Lock" has been set to "Off". If you connect multiple sources at the same time, press the "SOURCE" button on the control panel or direct source keys on the remote control to switch between inputs.

If you are still unable to get the unit to turn on, try unplugging it for 10 minutes and plugging it back in. If it still ceases to work, contact Optoma here: http://www.optomausa.com/rma_policy.asp

I have a motorola AP-300 which keeps on blinking amber light when i turn it on. how can i reset it or what's wrong with the AP?


From the installation guide for this AP, I find the following:

LED Indicators

The unit has LED activity indicators on the front of the case provide a status display indicating error conditions, transmission, and network activity for the 802.11a (amber) radio or the 802.11b/g (green) radio.


802.11a Activity LED Amber

The amber LED flashes three times per second until firmware is loaded. During boot, 802.11a mobiles cannot associate. After adoption, the amber LED is steady or flashes with 802.11a radio traffic.

The amber LED flashes once per second if an error prevents the 802.11a radio from operating normally.


802.11b/g Activity LED Green

The green LED flashes three times per second until firmware is loaded. During boot, 802.11b/g mobiles cannot associate. After adoption, the green LED is steady or flashes with 802.11b/g radio traffic.

The green LED flashes once per second if an error prevents the 802.11b/g radio from operating normally.


From this, it appears that the 802.11A radio is malfunctioning.


Here is the Motorola support web page for this device.

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

Powers On if I plug it in, and power supply fan runs...


Think of blinking amber as the initial state of the LED. As long as the system is receiving power from a power source and can pass that power through the system board to the LED on the Control Panel it should, at least, blink amber. As a result, a blinking amber Power Button LED is a reliable indicator that the system is receiving power from a power source. This, in turn, tells us that the source and power cord are likely to be functional. The Blinking Amber LED also tells us that the power supply to system board connection is good as well as the connections between the system board, I/O Panel and Control Panel. Depending on the components installed and the condition of those components, the LED may progress past blinking amber and move to solid amber. If the LED does not progress past blinking amber it indicates that the system is not able to properly distribute power to the system components. This is discussed in the next section of the interaction.


It does not indicate that the power supply is bad. It simply indicates that, for whatever reason, one of the power supply 'rails' is not operating within its specified range or, simply, that there is a short somewhere in the system.
The LED state could be the result of a misconfigured or incorrectly installed system component. A bad drive, for example, may be shorting out one of the rails. Incorrectly installed memory can cause a blinking amber front panel power button LED.
