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.
Notas:
• The Lenovo Solution Center program can be downloaded from http://www.lenovo.com/diags.
• If you are using other Windows operating system rather than Windows 7 and Windows 8, go to
http://www.lenovo.com/diags for the latest information on diagnostics for your computer.
To run the Lenovo Solution Center program on the Windows 7 operating system, see "Accessing Lenovo
programs on the Windows 7 operating system" na página 11.
For additional information, refer to the Lenovo Solution Center help system.
Nota: 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.
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.

If your computer is completely unresponsive, do the following:
1. Press and hold the power button until the computer turns off. After the computer is turned off, restart by

2. While the computer is turned off, remove all power sources from the computer (battery and the ac power
adapter). Hold down the power button for 10 seconds. Plug in the ac power adapter while keeping the
battery out of the computer. If the computer does not turn back on, continue with step 3.
