Double click on the "Smart Cover" icon on the desktop. Enter in the Smart Cover lock code if you have set one up and click on "Unlock" to disengage the hardware lock that prevents the case panel from being opened.
Click on the "Start" button at the bottom toolbar of the desktop and choose "Shut Down." Unplug all of the cables from the back of the computer once it has finished powering down.
Set the Compaq computer case on its side and remove the two screws connected to the top and bottom ends of the case panel. Slide the panel to the left and pull it directly off the case.
Disconnect the SATA cables running from the power supply, drive bays and processor fan to the motherboard. Remove the screws holding any expansion cards you may have previously installed into the AGP ports on the lower right side of the motherboard and then pull the cards out.
Pull back the clamp holding the processor fan on. Pull the fan and then the processor off of the motherboard. Pull off the RAM modules from the motherboard.
Remove the screws holding the motherboard into place and pull the entire motherboard directly out of the case. Check the orientation of the replacement motherboard and make sure the USB ports and AGP expansion card slots are facing towards the back of the case. Lay the new motherboard down into the case onto the mounting screws sticking out of the bottom panel.
Place the processor back into its socket on the motherboard and connect the fan on top. Snap back on the fan clamp. Place the RAM modules back into their slots. Re-connect all of the SATA cables to the drive bays and power supply.
Set the side panel back onto the case and re-connect the case screws. Connect all of the cables into the back of the case and power the computer back on. Wait for the operating system to load to make sure the motherboard is working properly.
Navigate back to the Smart Cover program, enter in the password, and press the "Lock" button.
