General precautions for HP products

Retain the safety and operating instructions provided with the product for future reference. Follow all operating and usage instructions. Observe all warnings on the product and in the operating instructions.

To reduce the risk of fire, bodily injury, and damage to the equipment, observe the following precautions.

Damage requiring service
Unplug the product from the electrical outlet and take the product to an HP authorized service provider under the following conditions:

  • The power cord, extension cord, or plug is damaged.
  • Liquid has been spilled or an object has fallen into the product.
  • The product has been exposed to water.
  • The product has been dropped or damaged in any way.
  • There are noticeable signs of overheating.
  • The product does not operate normally when you follow the operating instructions.

Except as explained elsewhere in the HP documentation, do not service any HP product yourself. Opening or removing covers that are marked with warning symbols or labels may expose you to electric shock. Service needed on components inside these compartments should be done by an HP authorized service provider.

Mounting accessories
Do not use the product on an unstable table, cart, stand, tripod, or bracket. The product may fall, causing serious bodily injury and serious damage to the product. Use only with a table, cart, stand, tripod, or bracket recommended by HP, or sold with the product.

Slots and openings in the product are provided for ventilation and should never be blocked or covered, since these ensure reliable operation of the product and protect it from overheating. The openings should never be blocked by placing the product on a bed, sofa, carpet, or other similar, flexible surface. The product should not be placed in a built-in apparatus such as a bookcase or rack unless the apparatus has been specifically designed to accommodate the product, proper ventilation is provided for the product, and the product instructions have been followed.

Water and moisture
Do not use the product in a wet location.

Grounded (earthed) products
Some products are equipped with a three-wire electrical grounding-type plug that has a third pin for grounding. This plug only fits into a grounded electrical outlet. This is a safety feature. Do not defeat the safety purpose of the grounding-type plug by trying to insert it into a non-grounded outlet. If you cannot insert the plug into the outlet, contact your electrician to replace the obsolete outlet.

Power sources
The product should be operated only from the type of power source indicated on the product's electrical ratings label. If you have questions about the type of power source to use, contact your HP authorized service provider or local power company. For a product that operates from battery power or other power sources, the operating instructions are included with the product.

Be sure that the power outlet you plug the power cord into is easily accessible and located as close to the equipment operator as possible. When you need to disconnect power to the equipment, be sure to unplug the power cord from the electrical outlet.

Voltage select switch
Ensure that the voltage select switch, if provided on the product, is in the correct position for the type of voltage in your country (115 VAC or 230 VAC).

Internal battery
Your computer may contain an internal battery-powered real-time clock circuit. Do not attempt to recharge the battery, disassemble it, immerse it in water, or dispose of it in fire. Replacement should be done by an HP authorized service provider using the HP replacement part for the computer.

Power cords
If you have not been provided with a power cord for your computer or for any AC-powered option intended for use with your computer, you should purchase a power cord that is approved for use in your country.

The power cord must be properly rated for the product and for the voltage and current marked on the product's electrical ratings label. The voltage and current rating of the cord should be greater than the voltage and current rating marked on the product. In addition, the diameter of the wire must be a minimum of 0.75 mm2 /18AWG and the cord should be between 5 and 8 feet (1.5 and 2.5 meters) long. If you have questions about the type of power cord to use, contact your HP authorized service provider.

Protective attachment plug
In some countries, the product cord set may be equipped with a wall plug having overload protection. This is a safety feature. If the plug needs to be replaced, be sure the HP authorized service provider uses a replacement plug specified by the manufacturer as having the same overload protection as the original plug.

Extension cord
If an extension cord or power strip is used, make sure that the cord or strip is rated for the product and that the total ampere ratings of all products plugged into the extension cord or power strip do not exceed 80% of the extension cord or strip ampere rating limit.

Do not overload an electrical outlet, power strip, or convenience receptacle. The overall system load must not exceed 80% of the branch circuit rating. If power strips are used, the load should not exceed 80% of the power strip input rating.

Unplug the product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.

The product should be placed away from radiators, heat registers, stoves, or other pieces of equipment (including amplifiers) that produce heat.

Circulation and cooling
Allow sufficient air circulation around the computer and the AC adapter during use and while charging the battery to ensure adequate cooling of the device. Prevent direct exposure to radiant heat sources.

Replacement parts
When replacement parts are required, be sure the service provider uses replacement parts specified by HP.

Safety check
Upon completion of any service or repairs to the product, have your HP authorized service provider perform any safety checks required by the repair procedure or by local codes to determine that the product is in proper operating condition.

Options and upgrades
Use only the options and upgrades recommended by HP.

Hot surfaces
Allow the equipment's internal components and hot-pluggable drives to cool before touching them.

Object entry
Never push a foreign object through an opening in the product.
