Suspend State

Status LED is Blinking Green. The display and backlight is 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 operator

tapped the Power key (1 beep) to place the MX1 in the Suspend state.

The Suspend Timer is reset every time the MX1 wakes up and normal activity occurs (keypresses,

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 MX1 is docked/not docked or by setting Docked PM Off in BIOS Setup.

If the 2

, Ctrl, Shift, or Alt keys were active (and the icons were on the display) when the MX1

entered Suspend, the function keys and their icons are cleared from the display when the MX1

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 MX1 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 MX1 off immediately when the main

battery is removed.

Once in the Critical Suspend state (and the main battery has not been replaced) the MX1 is

automatically turned Off when the Off Timer expires or the backup battery is depleted. When a

fully charged main battery is installed, the MX1 transitions to the Suspend state. Exit the Suspend

state by tapping the Power key.
