This Motherboard implements Flash ROM and a special circuit that allows you to save your current CPU and CMOS Setup
configurations without the need of a battery. The RTC (real time clock) can also keep running as long as the power cord is
plugged. If you lose your CMOS data by accident, you can just reload the CMOS configurations from Flash ROM and the system
will recover as usual.
ATX Stand-by Power Battery
Backup by EEPROM
Auto Switch
Auto switching to ATX standby power
as long as AC power line is plugged.
This smart design increases battery
life if you still plug battery on
motherboard.
