Repair your Compaq Presario laptop's motherboard.
The motherboard is the main circuit board built in to your laptop's interior. All hardware and electrical parts connect with your computer through the motherboard, which makes it your laptop's most important component. When the motherboard stops working, or behaves erratically, it can cause your hardware to malfunction at random intervals. It can even effect your laptop's power supply. Since motherboard diagnosis is often expensive and time-intensive, repairing your Compaq Presario 2200 laptop's motherboard means replacing it with a working board.
Instructions
1. Shut down the laptop. Unplug the power cable, and all peripheral devices. Close the display panel, and place the laptop face down. Slide the battery release button downward, and pull the battery pack out of its slot in the upper-right corner of the laptop.
2. Remove the memory modules, and its two Phillips-head screws from the center of the laptop. Spread apart the spring-loaded retention clips on each side of either module. Tilt each module upward at a 45-degree angle, and pull each module from its individual memory slot. Remove all screws from the laptop's bottom side, and place it so the top side is facing upward.
3. Open the display panel as far as possible. Remove the Phillips-head screws form the laptop's back panel. Use a flat-head screwdriver to disengage the keyboard cover's retention latches situated above the F3, F8, F11 and "Home" keys. The keyboard cover is the plastic piece above the top row of keyboard keys. Remove the cover from the laptop.
4. Loosen the four Phillips-head screws fastening the keyboard to the laptop. Lift the keyboard out of the laptop, and place it face down on the palm rest. Disconnect its ribbon cable from the motherboard. Remove the keyboard from the laptop. Locate the switchboard, which is a small circuit board revealed by the keyboard cover. Disconnect its cable from the motherboard, loosen its retaining Phillips-head screws and remove the switchboard from the laptop.
5. Locate the black, speaker assembly lining the top edge of the laptop's top casing. Disconnect its cables from the motherboard, and remove the Phillips-head screws fastening the speaker assembly to the laptop. Remove the speakers from the laptop.
6. Remove the two Phillips-head screws fastening the CD/DVD drive to the right side of the laptop. Insert a flat-head screwdriver into the vacant screw holes. Use the screwdriver to eject the drive from its compartment. Pull the drive out of the laptop through its slot on the right side of the laptop's casing.
7. Unplug all cables extending from either side of the display panel to the motherboard. Remove the three Phillips-head screws from each display hinge, and lift the entire display assembly from the laptop's base. Remove the two Phillips-head screws fastening the top cover to the laptop's base. Lift the top cover from the laptop, and unplug the touchpad's ribbon cable from the motherboard. Remove the top cover assembly from the laptop.
8. Loosen the three Phillips-head screws fastening the cooling fan assembly to the upper-left corner of the motherboard. Unplug its power cable, and remove the fan assembly from the laptop to reveal the processor chip. Turn the processor's locking screw in the counterclockwise direction. Lift the processor out of its motherboard socket, and set it aside.
9. Remove and disconnect all remaining screws and/or cables from the motherboard. Loosen the hex screws on each data port on the back side of the laptop's casing. Grasp the motherboard from the bottom edge, tilt it slightly upward and remove the motherboard from the laptop.
10. Repeat this procedure in reverse to install the new motherboard, and put your laptop together. All removed components must be transferred to the new motherboard.
