Things You'll Need
- Plastic containers
- Philips screwdriver
- Replacement screen
- Soldering iron
Close your laptop computer, flip it over and remove the battery. After you have removed the battery pack you will need to remove all the screws on the screen side of the computer. Remove a third screw that is located just under the battery in the middle of the computer. This is known as the keyboard screw. Place all the screws you use in separate plastic containers to keep track of them and to keep them organized.
Flip the computer back over and open the laptop back up. Hold the power button down for approximately 30 seconds to help make sure that all of the electric charge has been cleared out of the computer. Take your Philips screwdriver and remove the speaker bezel which is located just above the keyboard and right below the computer screen.
Disconnect all 6 wires connected to your laptop screen and speaker bezel. Your new screen will already have these particular wires attached to it, so all you have to do is disconnect the wires from the speaker bezel and not the actual screen itself. Remove the screws that are holding the hinges of the laptop screen to the body of the computer. Next, you will need to take your screwdriver and remove the keyboard screws, pull the keyboard up gently, and then carefully disconnect the main cable connecting the keyboard to the computer.
Disconnect the wireless antenna wires and remove them from the computer. Pay very close and careful attention how these wires are hooked up and how they are ran through the computer because your new wires will need to be hooked up the same way.
Take your brand new working computer screen and begin connecting and putting the laptop back together. Start by connecting the wireless antenna wires, and then reconnect the computer keyboard and screw it back in place.
Attach all the appropriate cables back in place on the speaker bezel on the laptop. Secure the hinges back in place and snap the speaker bezel cover back in place and screw it down. Flip the computer over and put the battery back in place and secure the screws firmly back in place.
Remove the motherboard from the laptop case (body). Take your soldering iron and desolder the power jack's connection to the motherboard.
Remove the power jack and begin cleaning the power jack and the motherboard. Make sure you use a very soft brush to clean away the dirt, dust, and other build up that may have gotten on the jack and motherboard.
Solder the power jack contacts to the motherboard. Once these connections have been made and soldered you can put the motherboard back into the laptop case.
