Chapter 8. Troubleshooting computer problems
This chapter provides information on what to do if you experience a problem with your computer.
This chapter contains the following topics:
• “Diagnosing problems” on page 89
• “Troubleshooting” on page 89
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 10, you can find the latest
information about diagnostics for your computer at:
http://www.lenovo.com/diags
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.
Troubleshooting
If your computer has an error, it typically displays a message or an error code, or a beep sounds 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 the instructions with your computer for reference later.
If your computer is completely unresponsive (you cannot use the TrackPoint pointing device or the
keyboard), do the following:
1. Press and hold the power button for four seconds or more to turn off the computer, and then restart the
computer by pressing the power button.
Note: If you cannot turn off your computer, or if you cannot restart it, continue with step 2.
