Strategy for replacing FRUs
Before replacing parts:
Make sure that all software fixes, drivers, and UEFI BIOS downloads are installed before you replace any
FRUs listed in this manual.
After a system board is replaced, ensure that the latest UEFI BIOS is loaded to the system board before you
complete the service action.
To download and install software fixes, drivers, and UEFI BIOS, go to http://www.lenovo.com/Drivers and
follow the instructions on the screen.
Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs:
• If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the
original FRU before you continue.
• Some computers have both a processor board and a system board. If you are instructed to replace either
the processor board or the system board, and replacing one of them does not correct the problem,
reinstall that board, and then replace the other one.
• If an adapter or a device consists of more than one FRU, any of the FRUs might 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 operation before replacing a hard disk drive. This will cause all customer
data on the hard disk drive to be lost. Be sure that the customer has a current backup of the data before
you perform this task.
