Service manual

Running the Dell Diagnostics: Dell Latitude CP
The RAM test group, the Video test group, the Serial/Infrared Ports test group, the Diskette
Drives test group, the Parallel Ports test group, the SCSI Devices test group, and the Hard-
Disk Drives (Non-SCSI) test group allow you to designate limits. Whether you select Test
Limits for a entire test group (from the Main menu) or a single subtest (from the Subtest menu),
you set the limits for all the subtests in that test group. When you select Test Limits, a new
screen appears and the Key Help area lists keys to use with the new screen.
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 in numbers over the digits of a given limit or by pressing the plus (+) or
minus (-) key to increase or decrease the given limit. In contrast, to set limits for the Serial
Ports test group, use the <Spacebar> to toggle between Yes and No.
After you are satisfied with the limits, press <Page Down> to select the next menu or submenu
in the Test Limits category. Press <Esc> to return to the main Test Limits menu. The values
you selected under Test Limits remain in effect until you change them or exit the diagnostics.
The values are reset to their defaults when you restart the diagnostics.
About
About in the Main menu displays information about the highlighted test group, such as limits
and parameters and how to set them.
Key-Help
Key-Help displays a list of key controls available for the selected option.
Quit
Select Quit from the Main menu (or press <q>) to exit the diagnostics and return to an MS-
DOS prompt.
After you return to the operating system environment, remove your diagnostics diskette from
drive A and reboot the computer.
CAUTION: It is important that you quit the diagnostics program correctly, because
the program writes data to the computer's memory that can cause problems
unless properly cleared.
