Location and purpose of the power dell gx280 error codes abcd button LED and the diagnostic LEDs. The diagnostic LEDs are located on the front of the dell post code abcd chassis and numbered 1, 2, 3, 4. The LEDs are located beneath the headphone and microphone jacks. These diagnostic LEDs are only active and visible dell abcd lights during the Power On Self-Test (POST) process. Once the operating system starts to load, they turn off and are no longer visible. The configuration of these LEDs along with the color state of the power button can help pinpoint a

potential problem with the system. Each LED has three possible states: OFF, ON, or BLINKING. Use the chart below as a reference for the different LED patterns and the possible system issues they indicate. Note: The diagnostic LEDs only serve as an indicator of the progress through the POST (Power On Self-Test) process. These LEDs do not indicate the problem that caused the POST routine to stop. For a more detailed description of the POST process and how to troubleshoot dell dimension 2400 abcd error codes issues with the system powering on and booting to Windows, refer to the article Why Won't my Desktop Computer Turn On? at the Dell support site.

A http://www.pctechbytes.com/dell/dell-diagnostic-lights/ -- If only the yellow ligth is lit, this means the computer is off and receiving power. A B C - If A B and C are yellow, this means the BIOS is not running or not finishing (completing its POST). B -- If B is yellow, this means you are having some type of issue with the power supply. C -- If C is yellow, this means you have some type of problem with the motherboard. A B D Yellow and C Green -This means you could have a problem with your CPU. A B Yellow and C D Green -- This means you have memory installed, but there is a problem with it.

You may have different diagnostic lights and still be able to boot, but a lot of those problems can be quickly fixed once you boot up the computer. One important thing you can try if you are receiving any of these critical conditions is to shut the system down, remove the plug and open the case. Make sure you touch a piece of metal on the case's chassis to ground yourself, then proceed to making sure all cables and cards are secure. Be careful not to touch any chips on the memory or the motherboard in the process.
