4.1 General 4 Replacement Procedures 4 1 4.1 General This chapter explains how to disassemble the computer 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. 4. 2 Battery Pack Bridge Media 4. 3 Memory Module 4.8 Top Cover 4. 4 HDD 4. 10 System Board 4. 11 Thermal module 4. 12 CPU 4. 5 ODD Bay Module 4. 6 Keyboard 4. 7 Wireless LAN Card 4. 9 Display Assembly 4. 13 Display Mask 4. 16 Power board 4. 17 Speakers 4. 14 LCD Module 4.18 Switch bord and botton board 4.15 4.19 Card reader board and DC IN cable CCD board and MIC How to use the chart (two examples):  For removing the System Board: First, remove the top cover with the display assembly.
