16901A Logic Analysis System Service Guide

If the system is unplugged while it is off and then 
plugged back in, the system will not power on until the 
power button is pressed.

Using a Short Press of the Power Button

Pressing the power button on a frame for a short time (less 
than 2 seconds or so): 

Closes all programs that are running.

Writes all data to the disk.

Turns off the power supply.

If the power button is depressed for a short time (less than 
2 seconds or so) while another instrument has an open 
Remote Desktop connection to this instrument, a message on 
the logic analyzer screen (not on the remote desktop) will 
pop up asking if you really want to power down. Clicking 
the 'yes' button results in the above events. Clicking 'no' will 
prevent the shutdown and not answering the dialog box 
(neither clicking "Yes" or "No") will have no effect. Further 
short presses on the power button will have no effect.

Using a Long Press of the Power Button

Pressing the power button for more than 4 seconds will 
power the system down abruptly. Use this method only when 
other methods have not responded:

Programs that are running will not be shut down. Any 
data that has not been written to the disk will be lost.

Turns off the power supply.

If the system is unplugged while it is off and then 
plugged back in, the system will not power on until the 
power button is pressed.

If the system does not boot, the hard disk drive will need 
to be re- imaged.

Unplugging the Power Cord or Power Loss

Unplugging power while the instrument is turned on or a 
power loss is similar to the long press of the power button 
with one exception:

When the system is plugged back in, it will power up and 
boot into Windows.
