Diagnosing problems

Using the Lenovo Solution Center program

Note: The Lenovo Solution Center program is available only on some models that are preinstalled with the
Windows 7 operating system. If your Windows 7 model is not preinstalled with the program, you can
download it from http://www.lenovo.com/support.
The Lenovo Solution Center program enables you to troubleshoot and resolve computer problems. It
combines diagnostic tests, system information collection, security status, and support information, along
with hints and tips for maximum system performance.
When you are setting up your computer, the Lenovo Solution Center program prompts you to create recovery
media, which you can use to restore the hard disk drive to the factory default state. For more information,
see "Creating and using recovery media" on page 81.
To run the Lenovo Solution Center program, click Start ➙ All Programs ➙ Lenovo Solution Center. Then
follow the instructions on the screen.
For additional information, refer to the Lenovo Solution Center help system.
Note: If you are unable to isolate and repair the problem yourself after running the program, save and print
the log files created by the program. You will need the log files when you speak to a Lenovo technical
support representative.

Using Lenovo ThinkVantage Toolbox

solutions for them. It also includes automatic notification when action is required, computing assistance,

messages, a guidance also will be displayed to guide you to fix the problem.
For additional information, refer to the ThinkVantage Toolbox help system.
Note: If you are unable to isolate and repair the problem yourself after running the program, save and print
the log files created by the program. You will need the log files when you speak to a Lenovo technical
