Disassembly
bottom daughterboards
OPTIONAL FAX/MODEM MODULE, THE POWER BOARD, THE IR BOARD AND THE IO BRACKET
These are the remaining components which can be separated from the mainboard. None of these parts are
serviceable. If any develop problems, the entire daughterboard should be replaced.
Note: The PC Card socket is soldered directly to the mainboard and so is not removable.
FAX/MODEM MODULE (NOT SHOWN)
This daughterboard connects to the mainboard through the surface mounted socket JMDC1 ( A) and then to
the fax/modem port through cable connector B. It is held in place with a single screw at point C.
THE POWER BOARD
This daughterboard (D) connects to the mainboard through two multi-pin sockets JDD1 & JDD2 (E & F).
To separate the daughterboard, gently rock it from side to side as you pull it up from the mainboard. The
underside of the power board also has a strip of mylar insulation which should not be removed.
THE IR BOARD
This small daughterboard (G) contains the IrDA port and the ON/OFF switch. It is attached to the IO Bracket
with two (2) screws, H & I. It connects to the mainboard through cable J to socket JIR1 (K).
THE IO BRACKET
This bracket (L), is held to the mainboard by six nuts (M ~ R).
