Power Control
The power to your PiDesktop can be controlled in two ways; pressing the power button
on the PiDesktop or using a command line or GUI.
PiDesktop Power Button
OPERATION
Turn on
Shutdown
Forced Shutdown
Command Line & GUI
A reboot command can be sent from the command line or GUI. During the reboot
process the LED will flash. When the system has finished the shutdown process it will
automatically restart. During restart LED will be consistently on, not blinking.
Running the shutdown command from the command line or GUI will command the LED
flash for 30 seconds before shutting off, at which point the power to the PiDesktop will
be cut.
Safe Power Control
NOTE: Directly cutting power to the RPi can cause damage to the board, therefore the
PiDesktop must perform safe startup and shutdown procedures.
