Diagnosing problems

If you experience problems with your computer, use the Lenovo Solution Center program as a starting point for solving them.

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.

Notes:

•The Lenovo Solution Center program also is available for downloaded at: http://www.lenovo.com/diags

•If you are using other Windows operating system rather than Windows 8.1, you can find the latest information about diagnostics for your computer at:

To run the Lenovo Solution Center program, see “Lenovo programs” on page 12.

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 Lenovo Solution Center 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.
