Environmental Specifications - HP Vectra VL400 Technical Reference Manual

Notes Operating temperature and humidity ranges may vary depending on the mass storage devices
installed. High humidity levels can cause improper operation of disk drives. Low humidity ranges
can aggravate static electricity problems and cause excessive wear of the disk surface.
The power consumption and acoustics figures given in the tables above are valid for the standard
configuration as shipped. For more information, refer to the product's data sheet at HP's web
When the computer is turned off with the power button on the front panel, the power
consumption falls below 3W, but it is not zero. The special on/off method used by these
computers considerably extends the lifetime of the power supply. To reach zero power
consumption in "off" mode, either unplug the power outlet or use a power block with a switch.
