Assembly Procedures
The computer must be re-assembled after disassembly and repair. While assembling the
computer, remember the following:
❑
Take adequate time, making sure to follow instructions closely. Most problems arise
when assembly is done in a hurry.
❑
Make sure cables and connectors are securely fastened.
❑
Before securing an FRU or other parts, make sure no cables will be pinched by screws
or the FRU.
❑
Check that all latches are closed securely.
❑
Make sure all the correct screws are used to secure FRUs. Using the wrong screw can
damage the threads or screw head, and may prevent proper FRU seating.
After re-assembly, verify that both the installed FRU and computer are functioning properly.
Tools and Equipment
The use of ElectroStatic Discharge (ESD) equipment is very important for personnel safety.
Proper use of these devices will also increase the success rate of repairs and lower the cost for
damaged or destroyed parts. The following equipment is necessary to disassemble and re-
assemble the computer:
❑
M2 Phillips screwdriver.
❑
Jeweler’s screwdriver.
❑
Tweezers to lift out screws.
❑
ESD mats for the floor and the table.
❑
ESD wrist strap or heel grounder.
❑
Anti-static carpeting or flooring.
❑
Air ionizers in highly static-sensitive areas.
❑
