Strategy for replacing FRUs

Before replacing parts:
Ensure that all software fixes, drivers, and UEFI BIOS downloads are installed before replacing 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
completing the service action.
To download software fixes, drivers, and UEFI BIOS, do as follows:
1. Go to http://www.lenovo.com/support.
2. Click Download Drivers & Software and then follow the instructions on the screen to reach the
Download Drivers and Software page.
3. Follow the directions on the screen and install the necessary software.
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.
