suspected hardware problem, run the hard-disk–based diagnostics by follow-
ing these steps:
If you wait too long and the operating system begins to load into memory,
let the system complete the load operation ; then shut down the system
and try again.
Starting the diagnostics causes the Dell logo to appear on the monitor
screen, followed by a message indicating that the diagnostics is loading.
Before the diagnostics loads, a program tests the portion of main memory
(RAM) required for loading the diagnostics. If a main memory error is
detected, a message indicates which DIMM has failed. If no errors are
found in main memory, the diagnostics loads and the Diagnostics Menu
appears.
This menu lets you choose the following options or exit to the MS-DOS
prompt:
Run Quick Tests — Runs selected tests from all test groups to quickly
locate a failure or to indicate where further testing is needed to isolate
a failure
Run All Tests — Runs all tests for a thorough test of the system
Run Specific Tests — Tests a particular area or subsystem
If the Diagnostics Menu does not appear, check with the network adminis-
trator to determine if the service partition was removed from the hard-disk
drive. If it is not possible to run the hard-disk–based diagnostics and if you
are prepared to remove the computer cover, see "Internal Visual Inspec-
tion" found earlier in this chapter. Otherwise, see "Getting Help" found
later in this chapter.
The hard-disk–based diagnostics consists of the following test groups:
RAM Tests — Check all the directly addressable RAM
System Set Tests — Check the computer's system board components and
verify their related functions
Video Tests — Verify proper operation of the video controller and the video
control circuitry
Keyboard Tests — Verify the correct operation of the keyboard and the key-
board controller chip
Mouse Test — Checks the functionality of the mouse controller and the
operation of the mouse keys
