Upgrading and Servicing the PC

Safety Information

Before you get started, please read this important

safety information about your HP Pavilion

home PC.

This product has not been evaluated for

connection to an “IT” power system (an AC

distribution system with no direct connection to

earth, according to IEC 60950).

AC Power Safety Warnings

The power supply is pre-set for the country/region in which

you purchased the HP Pavilion. If you move to another

country/region, please make sure you check its voltage

requirements before plugging your PC into an AC power

outlet.

Install the computer near an AC outlet. The AC power cord

is your HP Pavilion PC’s main AC disconnecting device and

must be easily accessible at all times. For your safety, the

power cord provided with your system has a grounded

plug. Always use the power cord with a properly grounded

wall outlet to avoid the risk of electrical shock.

To reduce the possibility of an electric shock from the

telephone network, always plug your computer into the AC

outlet before connecting it to the telephone line. Also,

always disconnect the telephone line before unplugging

your computer from the AC power outlet. Failure to do so

before you open the PC or do any procedures can result in

personal injury, or equipment damage.

Your system is provided with a voltage select switch for use

in a 115 or 230 VAC power system. The voltage select

switch has been pre-set to the correct voltage setting for use

in the particular country/region where it was initially sold.

Changing the voltage select switch to the incorrect position

can damage your PC and void any implied warranty.

Always disconnect the modem cord from the telephone

system before installing or removing your computer cover.

Do not operate the computer with the cover removed.

The power supply is not user-serviceable. To prevent

damage to the power supply, have a qualified person repair

or replace it. All other components are user-serviceable.

Electrostatic discharge (ESD) can damage disk drives, add-in

cards, and other components. If an ESD station is not

available, wear a wrist strap attached to a metal part of the

computer. Place cards on a conductive foam pad or inside

the card wrapper, if possible, but never on the card

wrapper.

The PC is heavy; be sure to use ergonomically correct lifting

procedures when moving the computer.
