Strategy
for
replacing
a
hard
disk
drive
Always
try
to
run
a
low-level
format
before
replacing
a
hard
disk
drive.
This
will
cause
all
customer
data
on
the
hard
disk
to
be
lost.
Be
sure
that
the
customer
has
a
current
backup
of
the
data
before
doing
this
task.
Attention:
The
drive
startup
sequence
in
the
computer
you
are
servicing
may
have
been
changed.
Be
extremely
careful
during
write
operations
such
as
copying,
saving,
or
formatting.
If
you
select
an
incorrect
drive,
data
or
programs
can
be
overwritten.
Important
notice
for
replacing
a
system
board
Some
components
mounted
on
a
system
board
are
very
sensitive.
Improper
handling
of
a
system
board
can
cause
damage
to
those
components,
and
may
cause
a
system
malfunction.
Attention:
When
handling
a
system
board:
v
Do
not
drop
a
system
board
or
apply
any
excessive
force
to
it.
v
Avoid
rough
handling
of
any
kind.
v
Avoid
bending
a
system
board
and
hard
pushing
to
prevent
cracking
at
each
BGA
(Ball
Grid
Array)
chipset.
How
to
use
error
messages
Use
the
error
codes
displayed
on
the
screen
to
diagnose
failures.
If
more
than
one
error
code
is
displayed,
begin
the
diagnosis
with
the
first
error
code.
Whatever
causes
the
first
error
code
may
also
cause
false
error
codes.
If
no
error
code
is
displayed,
see
whether
the
error
symptom
is
listed
in
the
Symptom-to-FRU
Index
for
the
computer
you
are
servicing.
