The special on/off method used by this PC Workstation extends the lifetime of the power supply. To reach zero power consumption in "off" mode, either unplug the PC Workstation from the power outlet or use a power block with a switch. You should be aware that the PC Workstation will lose its time settings within a few days if you unplug the PC, or switch off the PC Workstation at the power block. 4

System Overview
Specifications and Characteristic Data
Electrical Specifications
An attempt to draw too much current (such as a short circuit across edge-
connector pins, or an accessory board that is not suitable for these PC
Workstations), will cause the overload protection in the power supply to be
triggered, and the PC Workstation could fail to boot.
NOTE
When the PC Workstation is turned off with the power button on the front
panel, the power consumption falls below 5 Watts, but is not zero. The special
on/off method used by this PC Workstation extends the lifetime of the power
supply. To reach zero power consumption in “off” mode, either unplug the PC
Workstation from the power outlet or use a power block with a switch. You
should be aware that the PC Workstation will lose its time settings within a
few days if you unplug the PC, or switch off the PC Workstation at the power
block.
