important safety warnings
ÅWARNING: Avoid Electrical Shocks. To avoid electrical shock, do not open the power supplies. There
are no user-serviceable parts inside.
To avoid electrical shock and harm to your eyes by laser light, do not open the DVD laser module. The
laser module should be serviced by service personnel only. Do not attempt to make any adjustment to the
laser unit. Refer to the label on the DVD for power requirements and wavelength. This product is a class I
laser product.
ÅWARNING: Removing and Replacing the Cover. For your safety, never remove the system side cover
without first disconnecting the power cord from the power outlet and removing any connection to a
telecommunications network. If a Power Protection Device is fitted to your system, you must shut down
your computer using its on/off switch, then remove the power cord before removing the system’s side
cover. Remove the Power Protection Device cables before any servicing operation. Always replace the
side cover before switching the system on again.
ÅWARNING: Battery Safety Information. There is a danger of explosion if the battery is incorrectly
installed. For your safety, never attempt to recharge, disassemble, or burn an old battery. Replace the
battery with the same or equivalent type, as recommended by the manufacturer.
The battery in this system is a lithium battery that does not contain any heavy metals. However, to protect
the environment, do not dispose of batteries in household waste. Return used batteries either to the shop
from which you bought them, to the dealer from whom you purchased your system, or to HP so that they
can either be recycled or disposed of in the correct way. Returned batteries will be accepted free of
charge.
ÅWARNING: Avoid Burn Injuries. Some parts inside the computer will be hot. Wait approximately three
to five minutes for them to cool down before touching them.
ÄCAUTION: Avoid Static Electricity. Static electricity can damage electronic components. Turn OFF all
equipment before installing an accessory card. Don’t let your clothes touch any accessory card. To
equalize the static electricity when replacing an accessory card, rest the accessory card bag on top of the
system unit while you are removing the card from the bag. Handle the card as little as possible and with
care.
ÄCAUTION: Information on Ergonomic Issues. It is strongly recommended that you read the ergonomics
information, available in the “Working In Comfort” section of this manual, before using your system. You
can access more extensive ergonomics information at: www.hp.com/ergo
NOTE: Recycling Your System. HP has a strong commitment toward the environment. Your HP
system has been designed to respect the environment as much as possible. HP can also take back
your old system for recycling when it reaches the end of its useful life. HP has a product
take-back program in several countries. The collected equipment is sent to an HP recycling
facilities in Europe or the U.S.A. As many parts as possible are reused. The remainder is
recycled. Special care is taken for batteries and other potential toxic substances, these are
reduced into non-harmful components through special chemical processes. If you require more
details about the HP product take-back program, contact your local dealer or your nearest HP
Sales Office.

power specifications
Available power (output) is the maximum DC power that the power supply can supply to the
system.
Maximum input power is what the power supply requires from the AC line to deliver that
maximum DC output (given worst case efficiency and max loading).
Maximum input current is the worst case/highest current given the lowest input voltage and the
maximum input power.
The power supply has Active Power Factor Correction (APFC) that meets EN61000-3-2 over the
range of 88-255 VAC rms.

power consumption and cooling
The power consumptions listed in the following table are valid for a standard configuration as
shipped (4 GB of memory, 450W power supply, two hard disk drives, and one graphics card).
All information in this section is based on primary power consumptions.
environmental specifications
Operating temperature and humidity ranges may vary depending on the installed mass storage
devices. High humidity levels can cause improper disk operation. Low humidity levels can
aggravate static electricity problems and cause excessive wear of the disk surface.

■Power Button turns the system power on or off.
■Power LED is green when the power is on or the power button is pushed in. If the power is
on and the button is pushed in, the light will stay on even after the system is powered down.
When the button is released, the green light turns off.
■Activity LED indicates whether the system is accessing any of the hard drives or optical
drives (IDE or SCSI). If the LED is:
❏off, the system is off, or the system is not accessing internal drives
❏blinking green, the system is accessing an internal drive
NOTE: The Activity LED automatically communicates with IDE hard drives or optical drives.
To communicate with SCSI drives, a SCSI LED activity cable must connect the SCSI card and
the system board. The Activity LED is active only on systems purchased after March 2003.
■System and Diagnostic LEDs provide information about system errors.
■Locator Button and LED (rack-mount configuration only) identifies the rack position of
the workstation.

Installing or Replacing Parts and Accessories
removal and replacement prerequisites
Before you remove or replace parts, you must:
■Read the power and EMI warning and note below. (Your safety is important!)
■Gather your tools.
■Follow electrostatic discharge (ESD) precautions.
read the power and EMI warning and note
ÅWARNING: For the installation and removal procedures in this chapter, you must:
■power off the workstation, and
■unplug the workstation power cord from the AC power outlet.
NOTE: To maintain FCC Electromagnetic Interference (EMI) compliance, verify that all covers
are replaced and that all screws are properly seated.
gather your tools
You ne ed:
■Flat blade screwdriver
■T-15 Torx driver
■Special processor tool (provided with replacement CPU)
■Static-free mat
■Static strap
follow electrostatic discharge (ESD) precautions
To prevent damage to this system, observe all of the following ESD precautions while
performing the system parts removal/replacement procedures:
■Work on a static-free mat.
■Wear a static strap to ensure that any accumulated electrostatic charge is discharged from
your body to ground.
■Create a common ground for the equipment you are working on by connecting the static-free
mat, static strap and peripheral units to that piece of equipment.
■Keep uninstalled printed circuit boards in their protective antistatic bags.
■Handle printed circuit boards by their edges, once you have removed them from their
protective antistatic bags.
