•If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that changed the symptoms.

Strategy for replacing a hard disk drive

Always try to run a low-level format before replacing a hard disk drive (HDD). 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 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, the replacement parts also can be non-compliant. That is, if the original FRU parts are RoHS compliant, the replacement part also must be RoHS compliant.

Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified by the unique FRU part numbers.

Lenovo plans to transit to RoHS compliance before the implementation date and expects its suppliers to be ready to meet Lenovo’s requirements and schedule in the European Union. Products sold between 2005 and 2006 might contain some RoHS compliant FRUs. The following statement pertains to the products with RoHS compliant FRUs.

RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS implementation date, the failed RoHS compliant parts must be replaced with compliant parts and only the following FRUs can be used: identified as compliant in the Hardware Maintenance Manual or direct substitutions can be used.
