Diagnosing problems

If you experience problems with your computer, use diagnostic solutions as a starting point for solving them.
Depending on the preinstalled operating system and the date when your computer was manufactured,
Lenovo provides one of the following diagnostic solutions:
• Lenovo Solution Center: See "Using the Lenovo Solution Center program" on page 201.
• Lenovo ThinkVantage Toolbox: See "Using the Lenovo ThinkVantage Toolbox program" on page 201.
• Web-based diagnostic solutions: See "Using the Lenovo Support Web site" on page 202.
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/diagnose.
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 103.
To run the Lenovo Solution Center program, see "Accessing applications in Windows 7" on page 19.
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 the Lenovo ThinkVantage Toolbox program
The Lenovo ThinkVantage Toolbox program enables you to view symptoms of computer problems and find
solutions for them. It also includes automatic notification when action is required, computing assistance,
advanced diagnostics, and diagnostic history.
If the Lenovo ThinkVantage Toolbox program is available on your computer, do either of the following to
run the program:
• For Window 7: Click Start ➙ Control Panel ➙ System and Security ➙ Lenovo - System Healthy
and Diagnostics.
• For Windows XP and Windows Vista: Click Start ➙ All programs ➙ ThinkVantage ➙ Lenovo
ThinkVantage Toolbox.
