Strategy for replacing a hard disk drive, a solid-state drive, or an M.2
solid-state drive
Always try to run a low-level format operation before replacing a hard disk drive or 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 you perform this task.
Attention: The drive startup sequence in the computer you are servicing might 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.
If the computer is shipped with both an M.2 solid-state drive and a hard disk drive, the M.2 solid-state drive
®
is used for the "cache" function and to support the Intel Rapid Start Technology. We recommend that users
do not replace the M.2 solid-state drive by themselves. Otherwise, the "cache" function will not work and
the Intel Rapid Start Technology cannot be used any more.
Attention: Ensure that you partition the M.2 solid-state drive after installing it on the computer you are
servicing. Otherwise, the M.2 solid-state drive will not function correctly. For instructions on how to partition
an M.2 solid-state drive, go to http://www.lenovo.com/support/msata-fru.

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 might cause a system malfunction.
Attention: When handling a system board:
• Do not drop a system board or apply any excessive force to it.
• Avoid rough handling of any kind.
• Avoid bending a system board and pushing it hard to prevent cracking at each Ball Grid Array (BGA)
chipset.

How to use error message

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 might 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.

Strategy for replacing FRUs for CTO, special-bid, and standard models

This topic provides information about the model types and FRU identification.

Product definition

This topic introduces different model types and how to identify each type.
Dynamic Configure To Order (CTO) model
This model provides the ability for a customer to configure a Lenovo solution from a Web site, and have this
configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label and
eSupport will load these products as the 4-character MT, 4-character model, and 2-character country code.
The model is "CTO1" and the default country code is "WW" (example: 20AACTO1WW).
