d. Check for and replace defective hardware.
If a hardware component is not operating within specifications, it can cause unpredictable results.
Most hardware failures are reported as error codes in a system or operating-system log. See
“Troubleshooting tables” on page 53 and Chapter 7 “Installing and replacing FRUs” on page 143
for more information.
Troubleshooting procedures are also provided on the Lenovo Web site. A single problem might cause
multiple symptoms. Follow the diagnostic procedure for the most obvious symptom. If that procedure
does not diagnose the problem, use the procedure for another symptom, if possible.
For more troubleshooting information, see Chapter 5 “Diagnostics” on page 21.
If the problem remains, contact Lenovo or an approved warranty service provider for assistance
with additional problem determination and possible hardware replacement. Be prepared to provide
information about any error codes and collected data.
Undocumented problems
If you have completed the diagnostic procedure and the problem remains, the problem might not have been
previously identified by Lenovo. After you have verified that all code is at the latest level, all hardware and
software configurations are valid, and no EasyLED diagnostics LEDs or log entries indicate a hardware
component failure, contact Lenovo or an approved warranty service provider for assistance. Be prepared to
provide information about any error codes and collected data and the problem determination procedures
that you have used.
