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:
• 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 hard pushing to prevent cracking at each Ball Grid Array (BGA) chipset.
How to use error codes
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” section.
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 a Lenovo 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
Hardware Maintenance Manual
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 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.
• 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).
• The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” (example: 1829-CTO).
• eSupport will show both the CTO and CMV machine type models (example: 1829-CTO and 1829-W15 will
be found on the eSupport site.)
• The
Hardware Maintenance Manual
will have the 4-digit MT and 3-digit CTO model only (example:
1829-CTO). Again, CMVs are custom models and are not included in the
Hardware Maintenance Manual
.
