This chapter contains the following topics:
• "Diagnosing problems" on page 77
• "Troubleshooting" on page 77

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 optimal 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 7 or Windows 10, you can find the
latest information about diagnostics for your computer at:
http://www.lenovo.com/diagnose
When you are setting up your computer, the Lenovo Solution Center program prompts you to create recovery
media. You can use the recovery media to restore the hard disk drive to the factory default state. For more
information, see "Creating and using a recovery media" on page 95.
To run the Lenovo Solution Center program, see "Accessing Lenovo programs" on page 13.
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 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.

Troubleshooting

If your computer has an error, it typically displays a message or an error code, or makes a beep when
you turn it on. When you experience a problem, refer to the corresponding sections in this topic to try to
solve the problem by yourself.

Computer stops responding

Print these instructions now and keep it with your computer for reference later.
If your computer is completely unresponsive (you cannot use the ThinkPad pointing device or the keyboard),
do the following:
1. Press and hold the power button until the computer turns off. After the computer is turned off, restart by
pressing the power button. If the computer does not turn on, continue with step 2.
Note: Do not remove the battery and the ac power adapter to reset the computer.
