CAUTION:
Before reinstalling the heat sink you must clean the top of the processor and the bottom
of the heat sink with an alcohol pad supplied in the spares kit. After the alcohol has evaporated, apply
thermal grease to the top of the processor from the syringe supplied in the spares kit.
CAUTION:
When reconnecting the cables it is important that they be positioned so they do not
interfere with the rotation of the drive cage or power supply.
Battery
The battery that comes with your computer provides power to the real-time clock and has a lifetime of
about three years. When replacing the battery, use a battery equivalent to the battery originally
installed on the computer. The computer comes with a 3-volt lithium coin cell battery.
NOTE:
The lifetime of the lithium battery can be extended by plugging the computer into a live AC
wall socket. The lithium battery is only used when the computer is NOT connected to AC power.
