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 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.
