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:
• Lenovo System Toolbox (used to diagnose problems while running the Windows operating system)
• PC-Doctor for Windows PE (used when your Windows operating system does not start)
Notes:
1. You can also download the latest version of the Lenovo System Toolbox 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 after you run Lenovo System Toolbox and
PC-Doctor for Windows PE, save and print the log les created by both diagnostic programs. You will
need the log les when you speak to a Lenovo technical support representative. (The log le created by
Lenovo System Toolbox is automatically saved in C:\PCDR\DETAILED.txt.)
