If an error occurs during startup that cannot be reported on the monitor, your computer may emit a beep code that identifies the problem. The beep code is a pattern of sounds: for example, one beep, followed by a second beep, and then a burst of three beeps (code 1-1-3) means that the computer was unable to read the data in NVRAM. Some issues are caused by component failure or loose cables, others require hardware replacement.
If a beep code is emitted, write it down on a copy of the Diagnostics Checklist and look it up in the following table. If you are unable to resolve the problem by looking up the meaning of the beep code, use the Dell Diagnostics to identify a more serious cause. If you are still unable to resolve the problem, contact Dell for technical assistance.

Identifying Dell Computer Models Using the Model Code
On Sept 26, 2005 the System Setup program on certain Dell Dimension™, Inspiron™, and XPS™ computers was changed to display a model code instead of the computer model name. The Resource and Driver CD also lists the computer by this code. This may cause confusion when identifying which device drivers to install. If you are unable to identify your computer using the model code, refer to Table 1 below to determine the model name of your computer.
