Before performing any of the procedures in this chapter, read the following warning.
WARNING FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE
Before you start to work on the computer, perform the following steps in the sequence indicated.
1. Turn off the computer and any attached peripherals.
2. Disconnect the computer and any attached peripherals from electrical outlets to reduce the potential for personal injury or shock.
3. Ground yourself by attaching an antistatic grounding strap to your wrist and to an unpainted metal surface on the computer's I/O panel. If an antistatic grounding strap is not available, periodically discharge static electricity from your body by touching one of the connectors on the I/O panel.
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 system, 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 outlets 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 completely 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.
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.
7. Remove the hard-disk drive assembly.
CAUTION: When the hard-disk drive is not in the computer, store it in a hard-disk drive case to protect it from exposure to static electricity.
CAUTION: Handle the hard-disk drive gently and don't bump or drop the drive. Rough handling could induce failure or loss of data.
Loosen the two captive screws that secure the hard-disk drive into the bottom of the computer. The front edge of the cover pops up slightly. Slide the hard-disk drive toward the front of the computer and then lift the drive out of the computer (see Figure 4-7).
8. Remove the video card and memory module covers.
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.
Carefully spread the inner metal tabs of the memory module socket to disengage the module from the socket. The module should pop up slightly. Then pull the memory module out of the socket (see Figure 4-9).
10. Remove the video card.
Remove the two 3-mm screws securing the video card (see Figure 4-10). Gently pull the video card off of the connectors on the bottom of the system board by lifting it at the notches located between the screws. Do not rock the card to remove it because this may damage the connectors.
