Toshiba Tecra R840 Disassembly
It's manual didn't even mention the word "disassembly" and i coudn't found any docs from internet about how to disassemble it. So, i just disassembled. This is how: at first, you need to release all the screws placed in back side. then you can seperate the case from main body. after seperate back side (also seperate HDD) it's time to upper side. above the LCD, you can see four rubbers hiding screws. in mine's case, leftest and rightest has screws and middle 2 has no screws. DON'T force to pull layer. another step needed. below LCD, you can see the metal-like part. it also has sticker hiding screw. So release the screw and remove that two parts. then you can see this. to seperate upper's layer, you need to release that(front) screw. then you can remove the layer.
