1 System Overview
HP Kayak XM600 Desktop Specifications and Characteristics
If the overload protection in the power supply unit is triggered, all power is
immediately cut. To reset the power supply unit, remove the power cord and
then determine what caused the overload and remedy it. Reconnect the
power cord, then reboot the PC Workstation. If an overload happens twice,
then there is an undetected short circuit somewhere.
NOTE When the PC Workstation is turned off with the power button on the front
panel, the power consumption falls below the low power consumption (refer
to the below table), 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.
Desktop Power Consumption and Cooling
The power consumption and acoustics given in the below table is valid for a
standard configuration as shipped (one processor, 256 MB of memory,
200 W power supply, one hard disk drive, video card, LAN card)
All information in this section is based on primary power consumptions.
