Error! Style not defined. Error! Style not defined. 4 Replacement Procedures

4.1 General

This chapter explains how to disassemble the laptop and replace Field Replaceable Units (FRUs).
Some replacement procedures may not require you to remove all the surrounding FRUs to
replace only one FRU. The chart below shows the FRUs in the order in which they should be
removed in a top-down manner, irrespective of their physical locations. The FRUs shown in the
top area of the chart should normally be removed before removing the FRUs shown in the
bottom area. To replace the FRUs, first identify the suspect FRU for the system failure. Next,
according to this chart, determine the FRUs that need to be removed before removing the suspect
FRU. After you determine those FRUs, go to the appropriate sections according to the section
numbers shown in the boxes. Then start removal and replacement.
