Appendix B. Getting help and technical assistance

will nd a wide variety of sources available from Lenovo to assist you. This section contains information
about where to go for additional information about Lenovo and Lenovo products, what to do if you
experience a problem with your system, and whom to call for service, if it is necessary.
Before you call
Before you call, make sure that you have taken these steps to try to solve the problem yourself:
• Check all cables to make sure that they are connected.
• Check the power switches to make sure that the system and any optional devices are turned on.
• Use the troubleshooting information in your system documentation, and use the diagnostic tools that
come with your system. Information about diagnostic tools is in the Hardware Maintenance Manual.
• Go to http://www.lenovo.com/support to check for technical information, hints, tips, and new device
drivers or to submit a request for information.
You can solve many problems without outside assistance by using the information available on the Lenovo
Support site or by following the troubleshooting procedures that Lenovo provides in the documentation
that is provided with your Lenovo product. The documentation that comes with Lenovo systems also
describes the diagnostic tests that you can perform. Most systems, operating systems, and programs come
with documentation that contains troubleshooting procedures and explanations of error messages and error
codes. If you suspect a software problem, see the documentation for the operating system or program.
Using the documentation
Information about your Lenovo system and preinstalled software, if any, or optional device is available in the
documentation that comes with the product. That documentation can include printed documents, online
documents, readme les, and help les. Most of the documentation for your server is on the documentation
DVD provided with your server. See the troubleshooting information in your system documentation for
instructions for using the diagnostic programs. The troubleshooting information or the diagnostic programs
might tell you that you need additional or updated device drivers or other software. Lenovo maintains pages
on the World Wide Web where you can get the latest technical information and download device drivers and
updates. To access these pages, go to http://www.lenovo.com/support and follow the instructions.
