This section explains how to disassemble the computer and replace Field Replaceable Units
(FRUs). It may not be necessary to remove all the FRUs in order to replace one. The chart
below is a guide to which FRUs need to be removed in order to remove others. Always start
by removing the battery pack, next, optional items such as the optional PC card and optional
SD card, then follow the line on the chart to determine which FRU you must remove next in
order to repair the one you think is causing the computer to operate improperly. Refer to the
