*Notes:
Due to limitations in Super I/O firmware, the behavior of Last State and Always On power mode settings in BIOS is affected if CMOS
battery is removed or dead.
- If battery is dead or not present, the power button must be used to power on the unit.
- After battery is replaced, the power button must be used to power up the unit the first boot. After that it will return to normal behavior.
- Note that the system will show warning during boot, if battery voltage is below set limit (default: 2,6V, can be changed in BIOS), giving
users time to plan service to replace the battery before the battery dies.
For setups where this limitation is not acceptable, the workaround is to set the system to AT mode. The system will then always start
when power is connected, and the BIOS settings are ignored.
- If this is required, please specify “AT mode” option when ordering new units, as it’s a jumper setting modified during production process
or by authorized service partner.
