This chapter describes the beep codes and error messages that are common to all members of the Dell OptiPlex GX1/GX1p Managed PC and OptiPlex NX1 Net PC family of computers. These error messages can occur during the POST or, in the case of some failures, during normal system operation. The tables in this chapter list faults that can cause a beep code or system error message to occur and the probable causes of the fault in each case. If a faulty system does not emit beep codes or display system error messages to indicate a failure, you should use the system diagnostics to run the appropriate tests to help isolate the source of the problem (see "Running the System Diagnostics" in Chapter 2). If the monitor cannot display error messages during the POST, the system may emit a series of beeps that identifies the problem or that can help you identify a faulty component or assembly. Table 3-1 lists the beep codes that may be generated during the POST. Most beep codes indicate a fatal error that prevents the system from completing the boot routine until the indicated condition is corrected. When the system emits a beep code, record the code and then find it in Table 3-1. If the table does not lead to the source of the problem, run the appropriate tests in the system diagnostics to assist in troubleshooting the problem. 1-1-3 1-1-4 1-2-1 1-2-2 1-2-3 NVRAM write/read failure BIOS checksum failure Programmable interval-timer failure Defective system board Faulty BIOS or defective system board Defective system board DMA initialization failure DMA page register write/ read failure Beep Codes and Error Messages 3-1
