Overview
This chapter describes the procedure for removing and replacing the field replaceable
units (FRUs) in the PC. It may not be necessary to remove all the FRUs in order to
replace one. The chart below provides a guide as to which other FRUs must be removed
before a particular FRU can be removed. The numbers in the chart indicate the relevant
section numbers in this manual.
In all cases when removing an FRU, the battery pack must also be removed. When
repairing an FRU that is the potential cause of a computer fault, use the chart to determine
the order in which FRUs need to be removed.
