Toshiba's are too bad... Most all have a bar just above the keyboard that must be removed (sometimes this his held down by screws under the battery). Get that off, pull the keyboard off but be careful of any ribbon cables. Once it's gone, there are usually 2-4 screws holding the cover down from the top. Get them out then start getting them from the bottom.
There are disassmbly guides here and there, but most laptops are pretty similar.
