Using the documentation and diagnostic programs
Many computer problems can be solved without outside assistance. If you
experience a problem with your computer, see Chapter 7, “Troubleshooting and
diagnostics,” on page 47. For information on additional resources to help you
troubleshoot your computer problem, see “Information resources” on page 53.
If you suspect a software problem, see the documentation, including README
files and online help, that comes with the operating system or application program.
Most computers come with a set of diagnostic programs that you can use to help
you identify hardware problems. For instructions on using the diagnostic
programs, see “Diagnostic programs” on page 48.
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.
