3 - 16 VC5090 Vehicle Computer Product Reference Guide

There are two reset functions, warm boot and cold 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 

 button on the Quick Access Panel simultaneously

or

•

tap 

 

> 

 > 

.

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 

, 

 and the 

 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.

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 

 > 

 > 

 

 > 

 icon > 

tab to set the time-out value.

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.

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

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