Shut down the Laptop:
First off note which type of screen your laptop has and purchase one that is guaranteed to fit. Once you are ready to replace the screen, shut down the computer, remove the battery and unplug it.
Remove the screws:
Locate the screw covers on the plastic frame to gain access to the screws that hold the screen to the bezel in pace. In most cases, your screen will have from 4 to 6 total screw covers. You will probably need a small flat head screw driver. Screw covers will usually be located on the bottom of the plastic frame; however every computer model is different, so you will have to search for the screw covers to gain access to the screen.
Pull away the screen:
Once all the screws are removed, gently pull away the screen from the plastic bezel. Usually the best way to accomplish this is to use your fingers to gently roll around the entire bezel loosening the screen. Once you rolled your fingers all around the bezel slightly separating the screen, pull the screen away from the bezel using a light to moderate amount of force.
Disconnect the wires:
Now that the bezel has been removed, you should see the screen surrounded by its metal frame. At this point, you can tilt the screen forward, exposing the metal back of the LCD frame. You should be able to see the wires running from the screen to the laptop. There should be two main wires; the first is a ribbon which is the video cable. The video cable is usually taped in place. Remove the tape and then gently disconnect the ribbon from the LCD screen. The other wire is the power cable for the inverter. In most cases, if you are just replacing the LCD screen, you will continue to use the inverter, leaving it as is. However, if you are replacing the inverter as well, disconnect the power cable and unscrew the inverter from its mount.
Plug New Screen. :
Once your old screen has been removed, plug in the new screen and set it in the shell. However, before you screw in the bezels, you should test the screen to make sure it is working properly. In order to test the screen, you will need to power up your computer. If when you power up your computer, the screen is working properly, you can shut down the computer and continue to screw in the screen to the bezel and cover the screws with the plastic or rubber caps.
The replacement of your screen is complete. Replacing your laptop screen on your own is a great way to save lots of money not only on the cost of the laptop screen, but the cost of labor as well.
