Lenovo 1050 Hardware Maintenance Manual

16

This chapter presents the following important service information:
• “Strategy for replacing FRUs” on page 16

—

“Important notice for replacing a system board” on page 17

• “Important information about replacing RoHS compliant FRUs” on page 18

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.

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.

Important service information

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/.
