Dell Latitude CS Portable Computers Service Manual
If the socket is type A
, use a flat-blade screwdriver to turn the cam
180 degrees counterclockwise. When the cam is in the open position, the
triangular-shaped pointer on the cam points toward the ³O´ (open
position), and a view window, on the lower right-hand side of the cam,
displays a full circle (see Figure 20, type-A socket). Grasp the edges of the
microprocessor to lift it out of the socket.
If the socket is type B
, use a Phillips-head or a flat-blade screwdriver to turn
the cam 180 degrees counterclockwise. When the cam is in the open
position, a tab on the cam points toward the ³O´ (open position) (see
Figure 20, type-B socket). Grasp the edges of the microprocessor to lift it
out of the socket.

15. Remove the two M2 x 4-mm screws located on the back corners of the
hard-disk drive bay that attach the hard-disk drive electromagnetic
interference (EMI) clips to the system board.
16. Install a new microprocessor.
To install a microprocessor in a type-A socket
, place the microprocessor in
the socket and use a flat-blade screwdriver to turn the triangular-shaped
pointer on the cam clockwise 180 degrees toward the ³L´ (locked
position). The view window displays a half circle when the cam is in the
locked position (see Figure 20, type-A socket).
To install a microprocessor in a type-B socket
, place the microprocessor in
the socket and use a Phillips-head or flat-blade screwdriver to turn the cam
clockwise 180 degrees so that the tab on the cam points toward the ³C´
(closed position) (see Figure 20, type-B socket).
NOTE: When replacing the microprocessor, save the package material from
the new microprocessor to repackage the old microprocessor for transport.
17.
Attach the hard-disk drive EMI clips and the PC Card cover to the new
system board assembly.
After replacing the system board assembly, be sure to enter the system²s
service tag number into the BIOS of the replacement system board assembly.
Insert the diskette that accompanied the replacement system board assembly
into the diskette drive, and turn on the computer. Follow the instructions on the
display screen.
