Dell Inspiron 7000 Service Manual page 30

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.
