System Sleep Timer

This parameter sets the system to the lowest power-saving mode. It automatically
enters into the sleep or the suspend mode after a specified period of inactivity.
Any keyboard or mouse action, or any modem activity detected (if the Modem
Ring option is enabled - see section 3.5.3) resumes system operation.
Stop CPU Clock in Sleep State
If you want to stop the CPU clock when the system enters the sleep or suspend
mode, set this parameter to Yes. If not, select No.

When set to Power Off, the system automatically turns off when the power switch
is pressed for less than 4 seconds. When set to Suspend, the system enters the
suspend mode when pressed for less than 4 seconds.
3.5.3 Wakeup Event
This parameter lets you specify the activity that will return the system to normal
operating mode.

Modem Ring

Enable this item if you want to specify modem activity as your system wakeup
event. This means that any modem activity detected will wake up the system.
