The Dell Diagnostics contains tests that aid in troubleshooting the computer. 
The diagnostics diskette contains the following test groups:
‡RAM — Tests the main memory
‡System Set — Tests the primary functions of the main board
‡Video — Tests the video subsystem
‡Keyboard — Tests the keyboard subsystem
‡Mouse — Tests the mouse/touch pad subsystem
‡Diskette Drives — Tests the diskette drive subsystem 5HDOWLPHFORFN

Before starting the Dell Diagnostics, you must configure the computer cor-
rectly. For more information, see “Before You Start Testing” in Chapter 4, 
“Running the Dell Diagnostics,” of the
 Reference and Troubleshooting Guide.
Follow these steps to start the diagnostics: 
1. Install a CD-ROM drive in the options bay.
2. Turn off the computer.
3. Place a copy of the 
Dell Diagnostics Diskette in the diskette drive, and boot 
the computer.
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 a memory module has failed.
If no errors are found in main memory, the diagnostics loads, and the Diag-
nostics Menu appears. This menu lets you choose the following options or 
exit to the MS-DOS
® prompt:   
‡Run All Tests — Runs all tests for a thorough test of the computer
‡Run Quick Tests — Runs preselected tests to quickly locate a computer 
failure or to indicate where further testing is needed to isolate a failure
‡Run Specific Tests — Tests a particular area or subsystem of the 
computer

This chapter provides procedures for removing and replacing components and 
assemblies. Unless other wise noted, each of the procedures in this chapter 
assumes the following:
‡The computer and any attached peripherals are turned off and the peripher-
als are disconnected from the computer’s I/O panel.
‡A part can be replaced or installed by performing the removal procedure in 
reverse order.
When performing the procedures in this chapter that require the computer to 
be open, use a book or something similar to support the display assembly. The 
angle of the display assembly with respect to the base assembly should not 
exceed 170 degrees.
Locations or directions relative to the computer are shown in Figure 4-1 unless 
other wise specified.

							Removing and Replacing Parts 4-3
Precautionary measures include disconnecting the computer from the AC 
adapter and port replicator and removing the main battery, PC Cards, hard-disk 
drive, memory module cover, video card cover, memory modules, and devices 
in the options bay.
To take these precautionary measures, follow these steps:
1. Determine the power state of the computer.
If the system is on, go to step 2.
If you are unsure whether the system is on, shut down and restart the sys-
tem, and then go to step 2.
2. Turn off any attached peripherals, and then shut down the computer.
3. Disconnect the computer and any attached peripherals from electrical out-
lets to reduce the potential for personal injury or shock.
If the computer has an AC adapter, disconnect the AC power cable from 
the electrical outlet and then from the AC adapter; then disconnect the AC 
adapter from the computer (see Figure 4-3) or from the Inspiron Port 
Replicator II.

4. If the computer is connected to a port replicator, pull both release handles 
on the sides of the replicator to undock the computer (see Figure 4-4).

5. Remove the main battery from the battery compartment.    
Unlock the latch lock on the bottom of the computer by flipping it toward 
the back of the computer (see Figure 4-5). Slide the latch release in the 
direction of the arrow. Keep holding the latch release with one hand while 
pulling the battery out of the compartment with the other.

The plastic front bezel on the battery slides back and forth, which allows it 
to be used in the options bay as a secondary battery, and can be removed.
On the back of the battery is a battery charge gauge. The five charge-level 
lights indicate the total battery charge, ranging from fully charged to com-
pletely discharged. Press the status button to the right of the lights to 
check the level of the total battery charge. See “Battery Charge Gauge” in 
Chapter 1 for more information.

6. Remove any PC Cards.   
To remove a type I or type II PC Card from the top connector (see 
Figure 4-6), press the top eject button twice. To remove a type 1 or type II 
PC Card from the bottom connector, press the bottom eject button twice. 
To remove a type III card, press the bottom eject button twice. 
NOTE: The first time you press an eject button, the eject button itself pops 
out. The second time you press the eject button, the PC Card is released 
and extends slightly from the slot.
Grasp the end of the card, and pull it completely from the slot.

Slide the video card cover as far as it will go in the direction of the arrow, 
and then remove the cover (see Figure 4-8). Remove the memory module 
cover in the same way.

To replace a cover, place it over the opening, leaving a small gap along the 
rounded edge, and then slide the cover toward the outside of the 
computer until it snaps into place.
