The Inspiron 7000 computer contains many screws of various sizes. To help 
keep track of the screws, use a tackle or pill box as a storage device. Use the 
location template in Table 4-2 to store the screws during disassembly.
Be careful not to scratch the computer plastic case by allowing the screws to 
get between the work surface and the plastic case. Dell suggests a soft 
padded work surface.

This section provides the removal procedure for the keyboard.
)LJXUH.H\ERDUG5HPRYDO
To remove the keyboard, follow these steps (see Figure 4-21):
1. Turn the computer over and remove the four 20-mm screws from the bot-
tom of the computer.
2. Turn the computer back over and open the display.
3. Insert a small flat-blade screwdriver or scribe along the right top of the key-
board, just above the row of function keys. Working from right to left, free 
the keyboard by prying it toward the front of the unit. When free, lift the 
top of the keyboard slightly to clear the palmrest assembly.
4. Slide the keyboard toward the display assembly to release the front edge 
of the keyboard from the palmrest assembly.
5. Rotate the bottom of the keyboard up toward the display assembly to 
expose the keyboard cable.
6. Disconnect the keyboard cable from ZIF connector JP14 on the system 
board. Use the pick to pry up the latches on each side of the connector.

The thermal shield serves as a heat shield for the system board, as well as an 
EMI fence for the processor board.
)LJXUH7KHUPDO6KLHOG5 HPRYDO
This procedure assumes that you have removed the keyboard. To remove the 
thermal shield, follow these steps (see Figure 4-22):
1. Remove the hinge covers.
Open the computer to 170 degrees, supporting the display assembly. From 
the outside edge of the unit, carefully insert a flat-blade screwdriver or 
scribe into the space on the inside of the hinge cover. Bring the tool against 
the front wall of the hinge cover and pull toward the keyboard to loosen the 
plastic snaps at the back of the hinge cover. Move the tool to the inside top 
of the hinge cover and lift the hinge cover off. If the hinge covers are tight, 
use a plastic wedge or scribe to loosen and pop them off. 
Be careful not to accidentally turn on the computer when removing the left 
hinge cover.

2. If your computer has an internal modem, disconnect the modem flex cable 
(see Figure 4-23) from connector JP20 on the system board and discon-
nect the twisted wire pair from connector JP2 on the RJ-11 card. Bend the 
cables back over the palmrest assembly to move them out of the way of 
the thermal shield.
3. Remove the four flat-head 4-mm screws and the one K-head 4-mm screw 
securing the thermal shield. Note that the K-head screw is leftmost and is 
thicker than the other four.
4. Remove the thermal shield from the palmrest assembly. Note that the bot-
tom of the shield has an EMI fence that surrounds the processor board.
5. If needed, remove the two screws securing the EMI fingers to the thermal 
shield and remove the fingers.
6. If you have an internal modem, remove it by inserting a screwdriver 
through the circular opening and pulling the modem carrier box carefully 
toward the back of the computer (see Figure 4-23). Lift the top off the 
metal carrier and remove the modem card if needed. Disconnect the flex 
cable from the modem card if needed.
