4 Replacement Procedures
4.1 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.
Chart Notation
