Important:
• If
the
computer
is
equipped
with
both
a
hard
disk
drive
and
an
mSATA
solid-state
drive,
do
not
use
the
mSATA
solid-state
drive
as
a
bootable
device.
The
mSATA
solid-state
drive
is
designed
and
developed
for
“cache”
function
purpose
only.
• Advise
customers
to
contact
the
Lenovo

Strategy
for
replacing
FRUs
Before
replacing
parts:
Ensure
that
all
software
fixes,
drivers,
and
UEFI
BIOS
downloads
are
installed
before
replacing
any
FRUs
listed
in
this
manual.
After
a
system
board
is
replaced,
ensure
that
the
latest
UEFI
BIOS
is
loaded
to
the
system
board
before
completing
the
service
action.
Use
the
following
strategy
to
prevent
unnecessary
expense
for
replacing
and
servicing
FRUs:
• If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the
original FRU before you continue.
• Some computers have both a processor board and a system board. If you are instructed to replace either
the processor board or the system board, and replacing one of them does not correct the problem,
reinstall that board, and then replace the other one.
• If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error.
Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change.
Replace only the FRU that changed the symptoms.
Strategy for replacing a hard disk drive, a hybrid drive, or a solid-state
drive
Always try to run a low-level format before replacing a hard disk drive, a hybrid drive, a solid-state drive.
This will cause all customer data on the drive to be lost. Be sure that the customer has a current backup of
the data before doing this task.
