							4.Repeat this procedure until the top edge of the keyboard is free. 
5.Tilt the top edge of the keyboard toward you to gain access to the two
keyboard cable connectors underneath the keyboard. 
6.Note that the wide keyboard connector attaches to the Main Board using 
a ZIF (zero insertion force ) type connector. To disconnect this cable,
gently pry the connector release mechanism to the right
approximately 1/8 which releases the ribbon cable.  
7.Gently lift upwards on the narrow ribbon cable (point cable) and remove
the cable from the main board connector. 
8.Remove the keyboard assembly from the notebook. 
9.When installing the replacement keyboard, essentially reverse the above
procedures. Insert the two cables into the connectors on the main
board; then tilt the keyboard and allow the three protruding metal
tabs along the front edge of the keyboard to enter the recessed areas.
Then gently press the top edge of the keyboard down beginning at the
left side and working across to the right side. 
n
Note: When installing the keyboard cables, note the orientation of the two
cables: the wide cable has a half- twist which places the metalized connec-
tor pins upwards. The small cable has the blue side pointing toward the left.
The ZIFconnector release mechanism must be open before inserting the ca-
ble; then press the locking  mechanism to the left until it is fully seated.

3. Turn the computer over and remove the two Phillips head screws located
along the edge of the panel (see Figure 5-7).
4.Using a small straight slot screwdriver, gently pry upwards on the disk
assembly. Then pull slightly to the left side to free the plastic lip along
the right side of the drive assembly.
5.Carefully flip the disk assembly on its back towards the left side of the
notebook. 
6.Using a small straight slot screw driver, gently pry on each end of the
connector on the Disk Drive and rock it back and forth util the
connector is removed from the drive assembly. 
n
Note:  To detach the hard drive from the plastic door, remove the four Torx
screws.
7.  Replacement is essentially the reverse of steps 1 through 7.

Assembly
The Top Cover Assembly protects all internal components housed in the
base assembly (Boards, Floppy Drive, Speaker, etc.  To open up the Base
Assembly for maintenance operations, perform the following procedure:
n
Note:  Removing the Top Cover Assembly will cause the PCMCIA Button
(P/N 9786086-1) and the Tamper Evident Warranty Label (P/N 9798834-2)
to become unusable.  Ensure that these components are in stock before re-
moving the Top Cover.

AC Adapter, if installed.
2.  Disconnect any peripheral device interface cables from the external
interface connectors and remove any installed PCMCIA options.

connectors are facing the front. Remove the two Torx head screws,
one adjacent to each notebook hinge. Tape this set of screws together. 
4.     With the notebook open, remove the three Torx-head screws and two
Phillips head screws from the perimeter of the keyboard recessed
area. Using tape,  tape  the screws together for ease of installation
later (label if you have difficulty remembering which screws go where).
5.   Close the Display Cover and flip the notebook over. Remove the three
Torx head screws from the three recessed areas (Figure 5-9) using the
long shank Torx driver. Then remove the Torx head screw located
under the Taper Evident Label near the Hard Drive assembly. Tape
this set of screws together. 
6.     Place a 1 thick, 8-1/2 X 11 book on the work surface behind the
notebook.  Flip the notebook right side up with the floppy drive facing
outwards. Then lift upwards gently allowing the Display and the Top
