Chapter 5. Diagnostics
Diagnostic programs are used to test hardware components of your computer and report
operating-system-controlled settings that can cause hardware failures. There are two diagnostic programs
preinstalled on your computer to help you diagnose problems:
• PC-Doctor for Windows (used when diagnosing problems while running the Windows operating system)
• PC-Doctor for Windows PE (used when your Windows operating system will not start)
Notes:
1. You can also download the latest version of the PC-Doctor for Windows and PC-Doctor for DOS
diagnostic programs from http://www.lenovo.com/support/.
2. If you are unable to isolate and repair the problem yourself by running the applicable version
of PC-Doctor, click the Save Button in the PC-Doctor-log-le display. You will need to have all
problem-related log les available when you speak to a Lenovo technical support representative.
PC-Doctor for Windows
PC-Doctor for Windows is a diagnostic program that works through the Windows operating system. The
PC-Doctor for Windows diagnostic program enables you to view symptoms and solutions for computer
problems, access the Lenovo troubleshooting center, update system drivers, and review system information.
To run PC-Doctor for Windows, open the Start menu from the Windows desktop, select All Programs, select
PC-Doctor for Windows, and click PC-Doctor for Windows. Follow the instructions on the screen.
For additional information about running the diagnostic program, refer to the PC-Doctor for Windows
help system.
If you still suspect a problem after PC-Doctor for Windows runs successfully, run PC-Doctor for DOS or
PC-Doctor for Windows PE to help you diagnose the computer problem.
PC Doctor for Windows also has problem determination aids that determine software and usage problems.
PC-Doctor for Windows PE
The PC-Doctor for Windows PE diagnostic program is part of the Rescue and Recovery™ workspace on
each Lenovo computer. Use PC-Doctor for Windows PE, if you are unable to start the Windows operating
system or if PC-Doctor for Windows has not been successful in isolating a possible problem.
Running diagnostics from the Rescue and Recovery workspace
You can run the PC-Doctor for Windows PE diagnostic program from the Rescue and Recovery workspace.
To run diagnostics from the Rescue and Recovery workspace, use the following procedure:
1. Shut down the operating system and turn off the computer.
2. Repeatedly press and release the F11 key as you turn on the computer.
3. When you hear beeps or see a logo screen, stop pressing the F11 key. The Rescue and Recovery
workspace opens.
4. From the Rescue and Recovery workspace, select Diagnose hardware.
5. The diagnostic program opens automatically. Select the diagnostic test you want to run. Press the F1
key for additional help.
