Diagnostic Codes, Beep Codes, and Error Messages 3-3
3267%HHS&RGHV
If the monitor cannot display error messages during the POST, the computer
may emit a series of beeps that identifies the problem or that can help identify
a faulty component or assembly. Table 3-2 lists the beep codes that may be
generated during POST.
When the system emits a beep code, record the code and then find it in
Table 3-2. If Table 3-2 does not lead to the source of the problem, run the
appropriate tests in the diskette-based diagnostics to assist in troubleshooting
the problem.
The USB port or a
device connected to it
has failed initialization.
Disconnect the device from
the USB port. Remove PCI

PCI cards. If the problem per-
sists, remove all but one card,
and then reboot. If the system
boots, add another card and
reboot. Repeat this step until
the malfunctioning card is
identified.
