from a power-off state only if it is connected to AC power. Press and hold the power button for 25 seconds. The system RTC
reset occurs after you release the power button.
NOTE: If AC power is disconnected from the system during the process or the power button is held longer than 40
seconds, the RTC reset process gets aborted.
