Replacement Procedures
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 all cases when removing an FRU, the battery pack must also be
