Power Status

Power On

Entered when external or/and good internal backup battery is connected. The backup battery is electrically
disconnected until the external power connected to the computer for the first time. In this state, The computer is up
and running, its components are powered up, and the display is on.

Low Power Mode

Entered only if the backup battery is connected. The computer looks like in "power off" state but vital system
components, including wake-up sources are still running. Other device components are either powered off, or put
in the lowest available power consumption modes.

Methods of Suspension

The VC70 operation can enter low power mode in three ways:
•
Manual suspension: the operator presses the Power button when the vehicle computer is on.
•
API suspension: the application requests a suspend via an API call.
•
Time-out suspension: suspends after the vehicle computer is not used for a set amount of time. Tap

IMPORTANT When replacing the forklift battery, avoid draining the internal backup battery of the VC70 by pressing

Critical Suspension

NOTE When the forklift truck is left to charge overnight, the VC70 switches to critical suspend mode. As soon as
external power is re-applied, the VC70 resumes from critical suspend mode. The process should take
couple of seconds to complete for all hardware components to wake up and all software configurations to
re-synchronize. Please allow the process to complete before starting using the VC70 (scanning, etc.). It is
also recommended to force a Warm Boot or a Cold Boot to start afresh, to have it done automatically; you
can use a registry key (see Force Warm Boot or Cold Boot After Resuming From Critical Suspension on
page 11-9).
Critical suspension occurs when input power is not available and the Backup battery is discharged to a low state
that is reserved for backup data retention.
During critical suspension all circuitry is shutdown except for memory retention and the real-time clock. During
critical suspension the VC70 is receiving power from the backup battery. The backup battery retains data for at
least 72 hours. Critical suspension occurs when the VC70 is receiving power from the Backup battery and the
battery discharges to a low capacity.
