Battery backed up RTC (Real Time Clock/Calendar) is built in an on-board 
CMOS (Complementary Metal Oxide Semiconductor) chip. The RTC keeps 
track of the time and date while the computer is off. The CMOS chip also stores 
system setup information. 
RTC battery is also recharged when AC adapter is attached. Recharge the 
computer approximately once per month to ensure RTC operation.
