Attention: The setup configuration on the computer you are servicing might have been customized. Running
Automatic Configuration might 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. Ensure 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 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 an mSATA solid-state drive and a hard disk drive, the mSATA solid-state
drive is used for the "cache" function only to support and the Intel Rapid Start Technology. Users are not
recommended to replace the mSATA solid-state drive by themselves. Otherwise, the "cache" function will
not work and the Intel Rapid Start Technology cannot be used any more.
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, 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), and eSupport 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.
