Running the System Diagnostics 125
Running the System Diagnostics
If you experience a problem with your system, run the diagnostics before 
calling for technical assistance. The purpose of the diagnostics is to test your 
system's hardware without requiring additional equipment or risking data 
loss. If you are unable to fix the problem yourself, service and support 
personnel can use diagnostics test results to help you solve the problem.
Using Online Diagnostics
To assess a system problem, first use the online diagnostics. Online 
Diagnostics is a suite of diagnostic programs, or test modules, that include 
diagnostic tests on chassis and storage components such as hard drives, 
physical memory, communications and printer ports, NICs, CMOS, and 
more. If you are unable to identify the problem using the online diagnostics, 
then use the embedded system diagnostics.
The files required to run the online diagnostics for systems running supported 
Microsoft
®
 Windows
®
 and Linux operating systems are available at 
support.dell.com and on the CDs that came with your system. For 
information about using diagnostics, see the Dell Online Diagnostics User's 
Guide.

device groups or devices. The system diagnostics menus and options allow 
you to:
• Run tests individually or collectively
• Control the sequence of tests

• Temporarily suspend testing if an error is detected or terminate testing 
when a user-defined error limit is reached
