A B C D -- No lights indicates the system is getting no power. You can confirm the outlet is working, but if you are still not getting power, you could have a problem with either the power supply, front switch or the http://www.pctechbytes.com/dell/dell-diagnostic-lights/ motherboard itself. A -- 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. These are the top Dell diagnostic lights and their conditions that can prevent your system from booting. 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.
