I want to get to the motherboard. how many screws are there?
Wear an antistatic wrist strap before you start dismantling the notebook. Doing so will prevent static electricity from damaging internal components.
Shut down the notebook, and remove its AC power cord and battery. Turn the laptop over and remove all marked screws from the bottom. Raise the plastic shells covering the hard drive, memory (RAM) and wireless card slots, and uninstall the components by lifting off the base. You may have to release locking clips to free the RAM module from its slot.
Turn the laptop around and detach the keyboard panel. Using a flat-head screwdriver, push inward on the four small latches holding the keyboard in place to disengage them. Lift the keyboard to remove it, and disconnect its flex cable. Remove the five screws from the exposed landing. Do not undo the screws securing the heat sink and CD-ROM drive.
Split the notebook casing open. Insert a pointy or flat-tipped implement between the top and bottom parts of the casing, and maneuver to detach the locking mechanisms holding the two parts together. Work your way all around the perimeter to detach and remove the top casing. Do not apply too much force, or you may break the plastic parts.
Remove the hinge covers holding the LCD panel. Unscrew the two plastic hinges to loosen the display assembly and its enclosed LCD screen. Locate and pry open the CMOS battery---a flat, circular component resembling a watch battery---from the motherboard. Disconnect the LCD cables, and detach the panel from the laptop by lifting it up from its position.
Undo all securing screws from the chipset and heat sink. Remove the components by gently raising, checking to ensure that you've disengaged all attachments. Remove the CD-ROM drive by unscrewing its attachment and detaching it from the notebook. With the optical drive off, disconnect the speaker's connecting wires and remove the speaker assembly.
Unscrew all points of attachment to release the motherboard from the notebook's chassis. Locate and undo all locking mechanisms, such as clips or hooks, to free the motherboard. Remove the plastic inserts for the modem, as well as the PCMCIA and SD card slots, and detach the motherboard. Move the board around a little to release it, and lift it off the notebook.
