Pushbutton Reset
Connector J13 includes an input for a pushbutton reset switch. Shorting J13 (pin 18) to ground
causes the Lion to reboot.
The input can be connected to ground using the normally open contacts of a pushbutton switch or
a relay, or with a switching transistor (open-collector or open-drain) capable of sinking 1 mA. The
input must be driven to a voltage between 0 V and 500 mV to be recognized by the Lion. Do not
add an external pull-up resistor to this signal.
This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
Speaker
Connector J13 includes a speaker output signal at pin 15. The VL-CBR-4005 paddleboard
provides a Piezo-electric speaker (as shown in Figure 7).
Video Interfaces
The two mini DisplayPort video interfaces support Extended Desktop, Clone, and Twin display
modes.
The optional VL-EPH-V6 video adapter card converts DisplayPort output to LVDS for flat panel
operation.

Working
All processor caches are flushed, and the CPUs stop executing instructions. Power to
the CPUs and RAM is maintained. Devices that do not indicate they must remain on may
be powered down.
Commonly referred to as Standby, Sleep, or Suspend-to-RAM. RAM remains powered.
Hibernation or Suspend-to-Disk. All content of main memory is saved to non-volatile
memory, such as a hard drive, and is powered down.
Soft Off. Almost the same as G3 Mechanical Off, except that the power supply still
provides power, at a minimum, to the power button to allow return to S0. A full reboot is
required. No previous content is retained. Other components may remain powered so
the computer can "wake" on input from the keyboard, clock, modem, LAN, or USB
device.
Mechanical off (ATX supply switch turned off).
