Strategy for replacing FRUs

Before replacing parts:
Ensure that all software fixes, drivers, and BIOS downloads are installed before replacing any FRUs listed in
this manual.
After a system board is replaced, ensure that the latest BIOS is installed to the system board before
completing the service action.
To download software fixes, drivers, and BIOS, do the following:
1. Go to http://www.lenovo.com/support.
2. Click Download Drivers & Software. The Web site offers three options to begin your search:
• Search by product number
• Search through the product auto-detect function
• Search by product category
3. Follow the directions on the screen and install the necessary software.
Notes: If you need to improve the computer performance, you also could download and install the latest
BIOS utility from the Support Web site.
• Do not try to update the BIOS settings for any computer unless you have been trained and certified. An
untrained person runs the risk of damaging the computer.
• Before installing the latest utility, ensure that the battery is fully charged and an ac power adapter is
connected.
• Do not turn off or put your computer into sleep or hibernation until the update has been completed.
Otherwise, the system board might be damaged.
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.
