1.6 CPU Thermal Protection
This mainboard implements special thermal protection circuits. When
temperature is higher than a predefined value, there will be a warning through
application software such as Hardware Monitor utility to notify user. It is
automatically implemented by BIOS and Hardware Monitor utility, no hardware
installation is needed.
1.7 Battery-less Design
To preserve the earth, AOpen MX3L 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, MX3L 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.
