Replacing the Battery
A coin-cell battery powers the Desktop Board’s real-time clock and CMOS memory.
When the computer is not plugged into a wall socket, the battery has an estimated life
of three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at
25 ºC with 3.3 VSB applied.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 17 on page 53 shows the location of the
battery.
CAUTION
Risk of explosion if the battery is replaced with an incorrect type. Batteries should be recycled where
possible. Disposal of used batteries must be in accordance with local environmental regulations.
