|If you are on about the plastic frame around the screen|
most have 4 screws under the rubber feet that protects the laptop when the lid is closed.
after you have removed them the plastic frame can be prised apart (some might have some glue on them but most dont they just click apart)
from the top down click it apart and the bottom usually has like a half circle type clip that pulls up
its all in one so pull towards you till you hit the bottom and then pull up
hope this makes sense if not search google and there are many videos etc for changing a lcd or inverter that need you to remove this
