Your laptop's outer shell is what protects its vital components. It is located beneath your laptop's keyboard and is somewhat difficult to access. If your laptop's outer shell becomes damaged, it is important to replace it right away to ensure the safety of your processor and video card. Replacing your laptop's shell casing can be accomplished in several steps.
Power down your laptop and disconnect any peripheral devices, such as your mouse and keyboards.
Remove the plastic hinges near the base of your laptop in order to remove the faceplate.
Remove your laptop's keyboard by removing the screws that secure it to your notebook's base. There should be four screws connecting your keyboard to your laptop.
Remove the outer shell that protects the internal components of your notebook computer. Depending on the brand of laptop, there will either be several screws or several plastic hinges holding it in place.
Install your new shell in the same fashion in which you removed the old one.
Reassemble your laptop to complete the operation.
