6 Configuring Remote Wake-Up Using Dell Client Command Suite
1 Wake on AC
The wake-on-AC BIOS feature controls the system’s behavior when AC power is restored. This feature is
present in desktops as AC Recovery with the options: ‘Power Off’, ‘Power On’, and ‘Last Power State’, and in
notebooks as Wake-On-AC with the options: ‘Enable’ and ‘Disable’.
After AC power is restored, the desktop briefly powers on to perform basic checks, including how the AC
Recovery feature is set. If the feature is set to:
 Power Off – The system is powered off.
 Power On – The system proceeds to boot.
 Last Power State – The system is powered on and then returns to its last state before the AC power
was removed. For example, if the system was powered on when a power outage occurred, when AC
power is restored, the system powers on automatically.
Note:
 If the desktop is in sleep mode (S3 state) and then loses AC power, the system is considered to be in
a powered on state.
 If the notebook (with or without batteries) is shutdown (S4 or S5 state) and has AC power applied,
then the Embedded Controller detects the event and powers on or off based on the configured
setting.
