Dell Latitude CP Service Manual page 27

This chapter describes system error messages that can occur during computer
startup or, in the case of some failures, during normal computer operation. The
tables in this chapter list POST error codes, battery failure codes, and system
error messages, as well as their probable causes.
If a faulty computer does not display a POST error code or system error mes-
sage to indicate a failure, use the Dell Diagnostics to help isolate the source of
the problem. See "Running the Dell Diagnostics" found later in this chapter.
If the computer's display cannot display error messages during the POST, the
numbers lock (Num Lock), the capitals lock (Caps Lock), and the Scroll Lock
indicators display codes that identify the problem or help you identify a faulty
component or assembly. The following table lists the error codes that may be
generated during POST. Most error codes indicate a fatal error that requires
replacement of the system board or other corrective actions before the com-
puter can operate.
NOTE: To display an error code, all three system indicators flash simulta-
neously (not sequentially). These "flash" codes are the same as the audible
"beep" codes used by the Dell Latitude XPi portable computer, for instance.
