Closing the Computer

1. To replace the bottom case, place it over the bottom of the computer in the same

orientation as the original bottom case.

2. Align the notches on the right and left sides of the case (some of these can be viewed

through the battery opening). Then press down and toward you slightly to secure the

case.

Important:

Make sure that the seams between the bottom case and the frame are

closed. Verify that the case lies flat and fits properly around the battery latch and that

the alignment tab that protrudes on the underside of the bottom case, shown in the

illustration

(Figure 13A)

, is seated properly.

Note:

To help with alignment, apply pressure to the bottom case at the back of the

battery compartment opening, near the latch, and on the front and back outside

edges of the case.

3. Check that the eight screw holes on the case align with the holes on the computer.

4. Replace the eight screws in the order shown in the illustration

(Figure 13)

. Do not

overtighten the screws or damage could result.

Note:

The screws must go in straight and easily; if they do not, readjust the bottom

case for proper alignment.

Important:

To avoid damaging the case, be careful that the screwdriver tip does not

slip out of the screw head during tightening.
