Chapter 3 Beep Codes and Error Messages This chapter describes beep codes and system error messages that can occur during system start-up 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 CD-based diagnostics to run the appropriate tests to help isolate the source of the problem. See "Running the System Diagnostics" in Chapter 2. POST Beep Codes 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 CD-based diagnostics to assist in troubleshooting the problem. Beep Code 1-2 1-2-2-3 1-3-1-1 1-3-1-3 Table 3-1. Beep Codes Error Probable Causes Invalid expansion-card ROM checksum Improperly seated expansion card, or system needs to be rebooted. Invalid BIOS ROM checksum Corrupted BIOS firmware or defective system board. DRAM refresh failure Defective DIMMs or system board. Reseat DIMMs or replace system board. Keyboard controller error Defective DIMMs or system board. Reseat DIMMs or replace system board. Beep Codes and Error Messages 3-1

his chapter describes beep codes and system error messages that can occur

operation. The tables in this chapter list faults that can cause a beep code or sys-

P
OST Beep Codes
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 gener-
ated 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 appro-
priate tests in the CD-based diagnostics to assist in troubleshooting the problem.
