Satellite C50-H/C40-H
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.
How to use the chart (two examples):

For removing the System Board:
First, remove Base Enclosure, Battery Pack and display assembly. Then, remove SSD, and
all cable, all of which are shown above the System Board.

For removing the LCD Module:
First, remove the display mask, both of which are shown above the LCD module.
