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. Make sure that the customer

has a current backup of the data before performing this action.

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 can cause damage to those components, and may cause a system

malfunction.

Attention:

When handling a system board:

•

Do not drop the system board or apply any excessive force to it.

•

Avoid rough handling of any kind.

•

Avoid bending the system board and hard pushing to prevent cracking at

each BGA (Ball Grid Array) chipset.

Important information about replacing RoHS

compliant FRUs

RoHS, The Restriction of Hazardous Substances in Electrical and

Electronic Equipment Directive (2002/95/EC) is a European Union legal

requirement affecting the global electronics industry. RoHS requirements

must be implemented on Lenovo products placed on the market after June

2006. Products on the market before June 2006 are not required to have

RoHS compliant parts. If the original FRU parts are non-compliant,

replacement parts can also be non-compliant. In all cases if the original

FRU parts are RoHS compliant, the replacement part must also be RoHS

compliant.

Note:

RoHS and non-RoHS FRU part numbers with the same fit and function

are identified with unique FRU part numbers.

Lenovo plans to transit to RoHS compliance well before the implementation

date and expects its suppliers to be ready to support Lenovo’s requirements and

schedule in the EU. Products sold in 2005 and 2006 will contain some RoHS

compliant FRUs. The following statement pertains to these products and any

product Lenovo produces containing RoHS compliant FRUs.

RoHS compliant FRUs have unique FRU part numbers. Before or after the

RoHS implementation date, failed RoHS compliant parts must always be

replaced with RoHS compliant ones, so only the FRUs identified as compliant in

the system HMM or direct substitutions for those FRUs may be used.
