3 - 16 VC5090 Vehicle Computer Product Reference Guide

Resetting the Vehicle Computer

There are two reset functions, warm boot and cold boot.

Performing a Warm Boot

A warm boot restarts the vehicle computer and saves all stored records and entries. In the Windows CE

environment.

To perform a warm boot:

• press the Power button and the

P2 button on the Quick Access Panel simultaneously

•tap >

Programs > Warm Boot.

Performing a Cold Boot

A cold boot restarts the vehicle computer. To perform a cold boot turn off the Main Power switch on the top of the

vehicle computer, simultaneously press the

P1, P3 and the Power button on the Quick Access Panel then turn on

the Main Power switch.

A cold boot also restarts the vehicle computer, but erases all stored records and entries in RAM. Data saved in

flash memory or a memory card is not lost. In addition it returns formats, preferences and other settings to the

factory default settings.

Methods of Suspension

VC5090 operation can be suspended 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 >

Settings > Control Panel > Power icon > Power Off tab to set the time-out value.

Critical Suspension

Critical suspension occurs when input power is not available and the UPS is either not installed or is discharged to

a very low state. During critical suspension all circuitry is shutdown except for memory retention and the real-time

clock. During critical suspension the VC5090 is receiving power from the backup battery or residual power from the

UPS. The backup battery retains data for at least 72 hours. Critical suspension occurs when:

• a VC5090 without a UPS is in suspend mode and external power is removed.

• the VC5090 is receiving power from the UPS and the UPS discharges.

NOTE Files that remain open during a warm boot may not be retained.

NOTE Any data previously synchronized with a computer can be restored during the next ActiveSync operation.
