Replacing the Clock/CMOS RAM Battery
A lithium battery is installed in a socket on the system board.
The battery has an estimated life expectancy of seven years. When the battery
starts to weaken, it loses voltage; when the voltage drops below a certain level, the
system settings stored in CMOS RAM (for example, the date and time) may be
wrong.
If the battery fails, you will need to replace it with a
Panasonic CR2032
battery or an
equivalent. As long as local ordinance permits, you may dispose of individual
batteries as normal rubbish. Do not expose batteries to excessive heat or any naked
flame. Keep all batteries away from children.
CAUTION!
Danger of explosion if the battery is incorrectly replaced. Replace only with the
same or equivalent type recommended by Viglen. Discard used batteries according
to manufacturer’s instructions.
The battery is listed as board component ‘L’ on the diagram on page 2.
It is located near to the Primary and Secondary IDE connectors (component ‘H’ on
the motherboard diagram).
To replace the battery, carry out the following:
1. Observe the precautions in “Before You Begin.”
2. Turn off all peripheral devices connected to the system.
3. Turn off the system.
4.
Figure 1
shows the battery location on the motherboard.
5. Remove any components that are blocking access to the battery.
6. Gently pry the battery free from its socket, taking care to note the "+" and "-"
orientation of the battery (
Figure 7
).
7. Install the new battery in the socket.
