How to Disassemble & Clean a Dell Latitude D630
- 1). Shut down the laptop and unplug the main power cable from the port on the back of the computer. Close the display panel, place the laptop face-down and rotate it so the front panel is facing you. Put on your antistatic wrist strap before continuing. Spread apart the battery pack's two release buttons. Lift the battery pack out of its compartment in the upper-right corner of the laptop. Put the battery in a static-free plastic bag and set it aside.
- 2). Remove any PCI expansion cards inserted into the card slot on the right side of the laptop. Press the ejection latch and pull the card from its slot in the laptop's case. Put the card in a static-free plastic bag while you finish cleaning the laptop.
- 3). Locate the CD/DVD drive in the upper-left corner of the laptop's bottom case. Remove the Phillips-head screw fastening the drive to its compartment in the side of the laptop. Press on the latch release on the face of the drive. Grasp the ejected latch and pull the drive through its compartment slot in the side of the laptop's case. Put the CD/DVD drive in a static-free plastic bag.
- 4). Unscrew the two Phillips-head screws securing the hard drive assembly to its compartment in the lower-right corner of the laptop. Pull the hard drive through the compartmental slot in the right side of the laptop. Put the hard drive in a static-free plastic bag. Remove all of the Phillips-head screws from the laptop's bottom case.
- 5). Place the laptop face-up and pull open the display panel as far as it will go. Insert a flat-head screwdriver into the right side of the plastic hinge cover, which is the plastic strip situated between the keyboard and display panel. Carefully pry the cover from the laptop and set it aside.
- 6). Unscrew the three Phillips-head screws from along the top edge of the keyboard assembly. Grasp the top edge of the keyboard, tilt it upward and unplug the keyboard's large ribbon cable from its motherboard connector. Remove the keyboard from the laptop completely. Put the keyboard in a static-free plastic bag while you finish cleaning the laptop.
- 7). Disconnect all cables extending from either side of the display panel to the motherboard. Remove the two Phillips-head screws from laptop's back panel just behind each display hinge. Lift the display panel off of the laptop's base and set it aside.
- 8). Remove the Phillips-head screws from the laptop's top casing. Grasp each end of the top case near the palm rest area. Unplug the touchpad cable extending from the touchpad device to the motherboard. Remove the entire top case from the laptop to reveal the motherboard.
- 9). Use a can of compressed air to thoroughly spray out all dust and debris from all the areas of the motherboard. This includes between cracks in the case and inside the vacant hard drive and DVD drive compartments.
Wet a soft-bristled brush with distilled water. Do not use any other type of water, such as tap or spring water, because the minerals can damage the motherboard. Wipe down dirt and dust spots with the wetted brush lightly. Wipe down the rest of the motherboard with a dry, lint-free washcloth. Allow the laptop to sit overnight to ensure that the entire motherboard and internal components have dried.
