Attention: The setup configuration on the computer you are servicing may have
been customized. Running Automatic Configuration may alter the settings. Note
the current configuration settings (using the View Configuration option); then,
when service has been completed, verify that those settings remain in effect.
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.
Strategy for replacing FRUs for CTO, CMV, and GAV
Product definition
Dynamic Configure To Order (CTO)
This provides the ability for a customer to configure an IBM
®
or a Lenovo
TM
solution from an eSite, and have this configuration sent to fulfillment, where it is
built and shipped directly to the customer. The machine label, Product Entitlement
Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit
MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).
Custom Model Variant (CMV)
This
is a unique configuration that has been negotiated between IBM or Lenovo
and the customer. A unique 4-digit MT and 3-digit model is provided to the
customer to place orders (Example: 1829-W15). A CMV is a special bid offering.
Therefore, it is NOT generally announced.
v The MTM portion of the machine label is the 4-digit MT and 3-digit model,
where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of the
machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15).
