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. For more information, see
“Troubleshooting tables” on page 64 and Chapter 7, “Installing optional
devices and replacing customer replaceable units,” on page 149. Hardware
errors are also indicated by EasyLED diagnostics LEDs.
A single problem might cause multiple symptoms. Follow the troubleshooting
procedure for the most obvious symptom. If that procedure does not
diagnose the problem, use the procedure for another symptom, if possible.
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.
