Replacing the Battery
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.
IF the voltage drops too low, 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 25 on page 59 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.
PRÉCAUTION
Risque d'explosion si la pile usagée est remplacée par une pile de type incorrect. Les
piles usagées doivent être recyclées dans la mesure du possible. La mise au rebut des
piles usagées doit respecter les réglementations locales en vigueur en matière de
protection de l'environnement.
