E-EQ-MX3RG-J-ARC MX3 Reference Guide
Power Management and the
Keypad
Status LED is Steady Green. When the MX3 is in the Display Off state, any keypress returns the
computer to the On state and the display activates. The key pressed (key value) is not sent to the
Operating System or application.
If the 2
nd
, Ctrl, Shift, or Alt keys were active (and the LEDs were illuminated) when the MX3
entered Display Off or Suspend, the modifier keys and their LEDs are cleared when the MX3
wakes up.
Suspend State
Status LED is Blinking Green. The display and all backlights are turned off.
The purpose of the Suspend state is to reduce the power consumption of the unit to a very low
point and still retain the condition of the processor and memory. This state is primarily meant for
breaks (lunch, afternoon) or for battery hot-swapping. The Suspend state is entered when the unit
is inactive for the amount of time set by the Suspend Timer (typically 5 minutes) or the user
tapped the Power key (1 beep) to place the MX3 in the Suspend state.
The Suspend Timer is reset every time the MX3 wakes up and normal activity occurs (keypresses,
touch screen, etc.). The Suspend Timer can be changed from its default time (5 minutes) in
incremental steps of one minute up to 63 minutes. The Suspend state can be disabled (Suspend
Timer set to 0) when the MX3 is docked/not docked or by setting PM Mode when Docked to
None in BIOS Setup.
If the 2
nd
, Ctrl, Shift, or Alt keys were active (and the LEDs were illuminated) when the MX3
entered Suspend, the function keys and their LEDs are cleared when the MX3 wakes up.
Critical Suspend State
Status LED is Blinking Red. The display and all backlights are turned off.
The Critical Suspend state is only entered when the main battery has failed or has been removed
and the unit is being powered by the backup battery. Once in this state, a fully charged backup
battery will provide enough energy to keep the unit in this state for at least 5 minutes. As the
energy in the backup battery is depleted, the unit will turn off and a reboot will be required.
Since the backup battery is supplying power in this state, the MX3 limits the amount of time it
stays in the Critical Suspend state via the Off Timer. The Off Timer is configurable in incremental
steps of one minute (the default is 5 minutes). The backup battery will supply power for at least
five minutes. As the Off Timer expires the unit will turn off and a reboot will be required.
Note: Setting the Off Timer to zero will then turn the MX3 off immediately when the main
battery is removed.
Once in the Critical Suspend state (and the main battery has not been replaced) the MX3 is
automatically turned Off when the Off Timer expires or the backup battery is depleted. When a
fully charged main battery is installed, the MX3 transitions to the Suspend state. Exit the Suspend
state by tapping the Power key. If the MX3 has a touch screen display, and configured for touch, a
pen-touch will exit the Suspend state.
