by removing the battery pack, next, optional items such as the optional PC card, optional
mini PCI card and optional memory module, 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 example at the bottom of the page.
