eplacing the Computer Cover
Use the following procedure to replace the computer cover:
1. Check all cable connections, especially those that
might have come loose during your work. Fold
cables out of the way so that they do not catch on
the computer cover.
2. Check to see that no tools or extra parts (includ-
ing screws) are left inside the computer.
3. Fit the cover over the chassis about 1 inch back of
the closed position; then lower the cover straight
down and slide it closed.
The tabs located at the bottom, sides, and top of the
front of the cover must slide inside the forms of the
chassis to ensure a good electromagnetic interfer-
ence (EMI) seal.
4. Install and tighten the four cover-mounting
screws on the back of the chassis.
Reinstall the special keylock screw in place of one of
the cover-mounting screws if you wish to prevent
unauthorized access to the interior of the computer.

the computer:

Protection of Your Equipment found earlier in this
chapter. Also observe the safety instructions at
the front of this guide.
2. Gently pry the bezel loose with your finger tips,
and remove it from the chassis (see Figure 6-2).
While prying the bezel loose, pry at different points
around the bezel to keep the opening between the
bezel and the chassis equal and help prevent damage
to the bezel.
