Assembly Procedures
After you have disassembled the T1900/T1900C and fixed or repaired the problem that was
causing the computer to operate abnormally, you will need to reassemble it.
While assembling the computer, remember the following general points:
❑
Take your time and make sure you follow the instructions closely. Most problems
arise when you get in a hurry.
❑
Make sure all cables and connectors are securely fastened.
❑
Before securing the FRU or other parts, make sure that no cables will be pinched
by screws or the FRU.
❑
Check that all latches are closed securely.
❑
Make sure the correct screws are used to secure all FRUs. Using the wrong screw
can damage the threads or the head of the screw, and may prevent proper seating of
an FRU.
After installing an FRU, confirm that it and the computer are functioning properly.
Tools and Equipment
The use of ElectroStatic Discharge (ESD) equipment is very important for your safety and the
safety of those around you. Proper use of these devices will increase the success rate of your
repairs and lower the cost for damaged or destroyed parts. The following equipment is neces-
sary to disassemble and reassemble the T1900/T1900C:
❑
One M2 Phillips-head screwdriver.
❑
A jeweler's screwdriver to remove screw masks.

❑
ESD mats for the floor and the table you are working on.
❑
An LCD support block composed of anti-static foam.
❑
An ESD wrist strap or heel grounder.
❑
Anti-static carpeting or flooring.
