8 Dell Latitude LM Service Manual Update
When you separate the top assembly from the bottom assembly, peal the kapton
tape from the EMI foil.
Before replacing the top assembly, replace the old EMI foil with a new EMI foil
and replace the old kapton tape with a new piece of kapton tape.
Bottom Assembly
The bottom assembly in your computer may have an I/O EMI shield and con-
ductive sponges in addition to the components shown in Figure 4-32.
Audio Board
The audio cable may be wrapped in EMI cloth.
C
hecking the Label
After replacing the old display, make sure the computer’s display label on the
back of the computer reflects the correct display in the computer by following
these steps:
1. Open the computer’s I/O panel door.
2. Check the label below the service tag (as you look at the back of the
computer).
If the label has the correct code for the display in the computer, no further
action is required.
If you replaced the display that was in the computer with a different display
(for instance, an IB display was replaced with an LG display), cross out the
preprinted code and write the code for the replacement display in the blank
space on the label.
If the computer does not have a display type label, place the blank label
(that came in the service kit) below the service tag and write in the code for
the display—for instance, IB, SA, or LG.
M
ain Board Switch
The following information supplements step 10 of the “Main Board” procedure
in Chapter 4:
• If you reinstall the main board with a Revision 5a main board, make sure the
DIP switch, SW2 (see the following figure), is set correctly for the type of
display, STN or TFT, in your computer.
• For an STN display, switches 1 and 4 are on and switches 2 and 3 are off.
• For a TFT display, switches 1 and 4 are off and switches 2 and 3 are on.
