computers come with the ability to produce a BIOS beep code when there is a serious hardware problem that prevents Windows from loading normally. Many Dell models have Dell diagnostic codes, as well as additional diagnostic lights to help users and repair technicians quickly troubleshoot problems. Dell Computer Error Codes In addition to a beep code, your Dell PC might have diagnostic lights on the front panel, lights in the rear labeled A,B,C and D and even a power supply LED. These advanced tools can generally point to the problem part if you know what you're looking for. Front Panel Lights Dell Computer Error Codes These lights are located on the front panel. They will change color and blink depending on the issue: A solid green light means the computer is powered on and functioning normally. A blinking green light means the computer is in stand-by. A solid yellow light means there is a device on the motherboard that may not be seated properly. A blinking yellow light means there is likely a problem with the motherboard or the power supply. If you have a solid green light but are still not booting, be sure to check your monitor connection, listen for beeps or check the rear of the PC for additional lights. Rear Lights Dell Computer Error Codes Rear LEDS are labled A through D and can change from green to yellow. Some typical LED reading might be: A - yellow, B - yellow, C - green, D - green <---- Indicates a problem with the RAM.
