Getting help and service

If you need help, service, technical assistance, or just want more information about Lenovo products, you
will find 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 our products, what to do if you experience a
problem with your computer, and whom to call for service should it be necessary.
Information about your computer and preinstalled software, if any, is available in the documentation that
comes with your computer. That documentation includes printed books, online books, README files, and
help files. In addition, information about Lenovo products is available on the World Wide Web.
Microsoft Service Packs are the latest software source for Windows product updates. They are available
via Web download (connection charges may apply) or via disc. For more specific information and links, go
to http://www.microsoft.com. Lenovo offers Up and Running technical assistance with installation of, or
questions related to, Service Packs for your Lenovo-preloaded Microsoft Windows product. For information,
please contact the "Customer Support Center" on page 236.

Using diagnostic programs

Many computer problems can be solved without outside assistance. If you experience a problem with your
computer, the first place to start is the troubleshooting information of your computer documentation. If you
suspect a software problem, see the documentation, including README files and online help, that comes
with the operating system or application program.
ThinkPad notebooks come with a set of diagnostic programs that you can use to help you identify hardware
problems. See Diagnosing programs for instructions on 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.
