POST beep codes A beep code is a combination of short or long beeps or a series of short beeps that are separated by pauses. For example, a "1-2-3" beep code is one short beep, a pause, two short beeps, a pause, and three short beeps. A beep code other than one beep indicates that POST has detected a problem. To determine the meaning of a beep code, see "Beep code descriptions." If no beep code sounds, see "No-beep symptoms" on page 42. Beep code descriptions The following table describes the beep codes and suggested actions to correct the detected problems. A single problem might cause more than one error message. When this occurs, correct the cause of the first error message. The other error messages usually will not occur the next time POST runs. Exception: If there are multiple error codes that indicate a microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See "Microprocessor problems" on page 59 for information about diagnosing microprocessor problems. v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 7996," on page 11 to determine which components are CRUs and which components are FRUs. v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician.

POST
beep
codes
A
beep
code
is
a
combination
of
short
or
long
beeps
or
a
series
of
short
beeps
that
are
separated
by
pauses.
For
example,
a
“1-2-3”
beep
code
is
one
short
beep,
a
pause,
two
short
beeps,
a
pause,
and
three
short
beeps.
A
beep
code
other
than
one
beep
indicates
that
POST
has
detected
a
problem.
To
determine
the
meaning
of
a
beep
code,
see
“Beep
code
descriptions.”
If
no
beep
code
sounds,
see
“No-beep
symptoms”
on
page
42.
Beep
code
descriptions
The
following
table
describes
the
beep
codes
and
suggested
actions
to
correct
the
detected
problems.
A
single
problem
might
cause
more
than
one
error
message.
When
this
occurs,
correct
the
cause
of
the
first
error
message.
The
other
error
messages
usually
will
not
occur
the
next
time
POST
runs.
Exception:
If
there
are
multiple
error
codes
that
indicate
a
microprocessor
error,
the
error
might
be
in
a
microprocessor
or
in
a
microprocessor
socket.
See
“Microprocessor
problems”
on
page
59
for
information
about
diagnosing
microprocessor
problems.
v
Follow
the
suggested
actions
in
the
order
in
which
they
are
listed
in
the
Action
column
until
the
problem
is
solved.
v
See
Chapter
3,
“Parts
listing,
Type
7996,”
on
page
11
to
determine
which
components
are
CRUs
and
which
components
are
FRUs.
v
If
an
action
step
is
preceded
by
“(Trained
service
technician
only),”
that
step
must
be
performed
only
by
a
trained
service
technician.
