Appendix A. Getting help and technical assistance
If you need help, service, or technical assistance or just want more information about Lenovo products, you
will find a wide variety of sources available from Lenovo to assist you.
Before you call
Before you call, there are several steps that you can take to try and solve the problem yourself. If you decide
that you do need to call for assistance, gather the information that will be needed by the service technician to
more quickly resolve your problem.
Attempt to resolve the problem yourself
You can solve many problems without outside assistance by following the troubleshooting procedures that
Lenovo provides in the online help or in the Lenovo product documentation. The Lenovo product
documentation also describes the diagnostic tests that you can perform. The documentation for most
systems, operating systems, and programs 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.
You can take 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.
• Check for updated software, firmware, and operating-system device drivers for your Lenovo product. The
Lenovo Warranty terms and conditions state that you, the owner of the Lenovo product, are responsible
for maintaining and updating all software and firmware for the product (unless it is covered by an
additional maintenance contract). Your service technician will request that you upgrade your software and
firmware if the problem has a documented solution within a software upgrade.

more efficiently if you prepare the appropriate information before you call. You can also go to

technician quickly provide a solution to your problem and ensure that you receive the level of service for
which you might have contracted.
