7-8 Dell Dimension XPS Dxxx Systems Reference and Troubleshooting Guide
How you change a value for the limits of a test group or subtest depends on the type
of parameter associated with it. Different keys are used to change values for different
types of parameters. For example, memory address limits specified for the RAM Test
Group are changed by typing numbers over the digits of a given limit or by pressing
the plus (+) or minus (-) keys to increase or decrease the given limit. In contrast, to set
limits for the Serial/Infrared Ports Test Group, you use the <Spacebar> to toggle
between Yes and No.
When you are satisfied with the limits, return to the Dell Diagnostics main screen by
pressing the <Esc> key. The values you selected under Test Limits remain in effect
for all the test groups or subtests you run, unless you change them. However, the
values are reset to their defaults when you restart the diagnostics.

To troubleshoot components or devices, run the appropriate test (test group or sub-
test) in the diagnostics. The diagnostics is organized by components into test groups
and subtests within each test group. Each subtest is designed to detect any errors
that may interfere with the normal operation of a specific computer device.
NOTES: Some subtests requiring hardware not listed in the System Configuration
area of the main screen appear to run, but they conclude with a status message
stating
Component not present (or disabled)
.
Some tests may fail if you have hardware that is not supported by your version of the
diagnostics; if a component is functioning normally, a diagnostics test failure may not
indicate a problem.
