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 com- puter 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 computer does not emit beep codes or display system error mes- sages to indicate a failure, you should load the diagnostics and run the appropriate tests to help isolate the source of the problem. See “Running the Dell Diagnostics” found later in this chapter.

If the display cannot display error messages during POST, the computer may emit a series of beeps that identifies the problem or that can help you identify a faulty component or assembly. For example, one beep, a burst of three short beeps, and two more single beeps (beep code 1-3-1-1) means that the system has encountered a DRAM refresh error condition, probably caused by a faulty system board.

Table 3-1 lists the beep codes that may be generated during POST. Most beep codes indicate a fatal error that requires replacement of the main board or other corrective actions before the computer can operate.
