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.
