1.7 Battery-less
Design
To preserve the earth, AOpen AX3L implements the battery-less motherboard
design. There is no need to have battery for RTC (real time clock) and CMOS
Setup as long as ATX power cable is plugged. In case of the AC power is
shutdown or power cord is removed by accident, the CMOS Setup and system
configuration can be restored from EEPROM, only the system clock needed to
be re-set to current date/time.
For the convenience of end user, AX3L still shipped with one Lithium (CR-
2032) battery. If you prefer to use battery, you can still insert it into battery
socket. The RTC will still keep running even power cord is removed.
