B. Tightening the
Computer Stand
See Figure 1. If the computer stand is
loose, use a screwdriver to turn the
screw (Detail 62) on each side of the
stand a quarter turn. If the display still
seems too loose, repeat this procedure
until desired friction is achieved.
C. Removing the
Upper Housing
To perform any operations on this unit,
you must remove the upper housing
(Detail 63).
Step 1
Place the unit face down on a protective
foam surface to prevent scratching.
Step 2
See Figure 2. Insert a large, flat-blade
screwdriver into the plastic cross-shaped
opening of the cam lock (Detail 1). Push
down on the plastic latch (Detail 2) while
rotating the cam lock (Detail 1) counter-
clockwise 90 degrees.
Once you’ve finished, the CD ROM and
floppy drives will have moved toward
the center of the machine (about .1
inch), and the plastic latch will have
moved from position (Detail 2) to posi-
tion (Detail 3). This action recesses the
floppy disk drive and CD ROM drive
from the upper housing (Detail 63),
enabling the computer to
be disassembled.

Step 3
Remove the 6 black pan-head torx screws
with a T-15 driver, as shown in Figure 2a.
Step 4
See Figure 3. Carefully position the unit so
that the LCD panel (Detail 7) is face up.
Avoid bending the metal lock tab (Detail 4)
on the back of the unit.
NOTE: Elevating the unit on two boards
will prevent damage to the metal lock tab.
Lift the upper housing (Detail 63) from the
computer assembly to access the interior.
Slightly rotate the stand higher than the top
of the LCD panel to release the upper hous-
ing (Detail 63) from the computer. (The
upper housing fits tightly, so slight rota-
tions, as depicted by the arrow heads in
Figure 3, might be required to remove the
upper housing completely.
