Environmental Specification
Operating temperature and humidity ranges may vary depending upon the
mass storage devices installed. High humidity levels can cause improper
operation of disk drives. Low humidity levels can aggravate static electricity
problems and cause excessive wear of the disk surface.

Acoustic noise emission less than 40 dB in the workplace under normal conditions as
defined by DIN 45635 T.19 and ISO 7779
Operating temperature +5°C to +40°C (+40°F to 104° F)
Recommended operating temperature +15°C to +40°C (+59°F to +104°F)
Storage temperature -40°C to +70°C (-40°F to +158°F)
Over temperature shutdown +50°C (+122°F)
Operating humidity 15% to 80% RH (non-condensing)

1 System Overview
Specifications and Characteristic Data
For the minitower models:
When the computer is turned off, but left plugged in at the mains, the power
consumption falls below 5 watts, but is not zero. A small trickle current
continues to flow, supplying power to the CMOS memory, considerably
extending the lifetime of the on-board battery.
If the computer is completely unplugged from the mains, the real time clock
continues to operate, from the charge stored in the battery.

Documentation
The table below summarizes the availability of documentation that is
appropriate to the HP Vectra VL and XA 5/xxx PCs. Three dots, ‘...’, are
used to indicate ‘VL’ or ‘XA’, as appropriate. Only selected publications are
available on paper. Most are available as printable files from the HP division
support servers, and as viewable files (which can also be printed) on the
HP Support Assistant CD-ROM.
Each PDF file (portable document format) can be viewed on the screen by
opening the file with Acrobat Reader. You can use the page-up, page-down,
goto page, search string functions to read the document on the screen.
(Note, though, that there is difference between the page number that is
printed on the page, and the page number that Acrobat Reader indicates,
because of the presence of the front matter pages). To print the document,
press Ctrl+P whilst you have the document on the screen.
