1.7
Real-Time Clock Subsystem
A coin-cell battery (CR2032) powers the 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 via the power supply 5 V STBY rail.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be
notified during the POST.
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 1 on page 13 shows the location of the battery.
