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 an 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 the service partner or local power company. For a product that operates from battery power or other power sources, the operating instructions are included with the product.

Accessibility

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

The 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 a service partner using the HP replacement part for the computer.

Power cords

If you have not been provided with a power cord for the computer or for any AC-powered option intended for use with the 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 the service partner.

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 service partner 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.
