16 Lenovo G470/G475/G570/G575 Hardware Maintenance Manual Important service information This chapter presents the following important service information: • “Strategy for replacing FRUs” on page 16 – “Strategy for replacing a hard disk drive” on page 17 – “Important notice for replacing a system board ” on page 17 • “Important information about replacing RoHS compliant FRUs” on page 18 Important: BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the customer support site: http://consumersupport.lenovo.com/. Strategy for replacing FRUs Before replacing parts: Make sure 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 loaded to the system board before completing the service action. To download software fixes, drivers, and BIOS, follow the steps below: 1. Go to http://consumersupport.lenovo.com/. 2. Enter a serial number or select a product or use Lenovo smart downloading. 3. Select the BIOS/Driver/Applications and download. 4. Follow the directions on the screen and install the necessary software.
Important service information Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: • If you are instructed to replace an FRU, but the replacement does not solve 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 of them, and replacing one of them does not solve 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 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. Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect. 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. 17
