VX7 Reference Guide 

The power (on/off) switch is a push button switch located on the front control panel of the VX7.  
The switch is a momentary switch.  If the VX7 is Off, pressing the power switch turns the VX7 
On. 

For Platform 2 VX7’s, the keyboard LEDs turn on for about one second when the operating 
system loads the keyboard driver.  If the LEDs blink more than once, this indicates a keyboard 
problem.   

•  On a USB or PS/2 keyboard, the NumLock, CapsLock and Scroll Lock keys blink 

the same as a desktop PC. 

•  On the 95-key keyboard, the CapsLock, NumLock and Scroll Lock keys are backlit 

amber.  However, the keyboard backlight must be On for this feature to be used.  
The brief illumination may not be visible unless the room is dark. 

•  On the 60-key keyboard, only the CAPs led is lit during this process. 

 

To identify your VX7 platform type, please see “Identifying Your VX7”, earlier in 
this chapter. 

If the VX7 is On, pressing and releasing the power switch turns the VX7 Off.  An orderly 
shutdown is preformed.  Any open programs are closed, the Windows CE operating system shuts 
down and then the VX7 powers off. 

If a software lockup should occur and the VX7 is unresponsive to keyboard or touchscreen input, 
pressing and holding the power button for several seconds forces a shutdown.  However, the 
forced shutdown is not an orderly shutdown.  All unsaved data and any registry settings not saved 
to persistent storage are lost. 

The Status LED, located on the keyboard of the VX7, is lit when the power is on: 

• 

 – VX7 is operating from vehicle power or AC power. 

• 

 – VX7 is operating from the UPS, UPS battery is good. 

• 

 – VX7 is operating from the UPS, UPS battery is critically low.
