4-2 Removal and Replacement Procedures
4.2 Disassembly Preparation
Before adding any internal options or performing a removal/replacement:
1. Remove any diskette, compact disc, or tape from the computer.
2. Turn off the computer and any peripheral devices that are connected to it.
WARNING:
Power is continuous to the system board and power supply even when the power
switch is turned off. To prevent damage to the unit, disconnect the power cord from the power
source or the unit before beginning disassembly procedures.
CAUTION:
Turn off the computer before disconnecting any cables.
3. Disconnect the power cord from the electrical outlet and then from the computer.
4. Disconnect all peripheral device cables from the computer.
✎
During disassembly, label each cable as you remove it, noting its position and
routing. Keep all screws with the components removed.
CAUTION:
The screws used in the computer are of different thread sizes and lengths; using the
wrong screw in an application may damage the unit.
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
CAUTION:
Static electricity can damage the electronic components of the computer or optional
equipment. Before beginning these procedures, ensure that you are discharged of static electricity
by briefly touching a grounded metal object. For more information, refer to Chapter 3, “Removal
and Replacement Preliminaries.”
