To replace the LCD panel, you must use an identical panel to ensure that it fits the plastic display housing. The upper half of the notebook body must be removed to provide access for plugging the display's signal cable into the system board. For more information, see the section "Liquid Crystal Displays."
C. External memory devices. Portable computers typically contain all the devices that users need to perform work away from the office; however, users have become accustomed to using additional items with their computers. For this reason, portables offer a wide range of I/O and expansion options to accommodate external FRU devices. The most common external devices used with portables include: external disk drives, external power sources and supplies, and External I/O devices. For more information, see the section "Portable Peripherals."
