Starting the diagnostics causes the Dell logo screen to appear, 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 appears on the
screen telling you which memory address failed.
If no errors are found in main memory, the diagnostics loads and the Diagnos-
tics 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 the failure or to indicate where further testing may be needed to iso-
late a failure
‡Run All Tests — Runs all tests for a thorough test of the computer
‡Run Specific Tests — Tests a particular area or subsystem
Removing and Replacing Parts 4-1 &+$37(5 5HPRYLQJDQG5HSODFLQJ3DUWV This chapter provides instructions for removing and replacing field- replaceable components, assemblies, and subassemblies. Unless otherwise noted, each procedure in this chapter assumes the following: ‡The computer and any attached peripherals are turned off, and the periph- erals are disconnected from the I/O panel on the back of the computer. ‡A part can be replaced by performing the removal procedure in reverse order. When the display assembly is open nearly 180 degrees, use a book or some- thing similar to support it. The angle of the display assembly with respect to the bottom case should never be allowed to exceed 180 degrees. Also, when performing the procedures in this chapter, the locations or directions relative to the computer are as shown in Figure 4-1 unless other wise specified. )LJXUH &RPSXWHU 2ULHQWDWLRQ right side left side back of computer front of computer
