Extension cords and related devices

Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use

are rated to handle the electrical requirements of the product. Never overload these devices. If power strips

are used, the load should not exceed the power strip input rating. Consult an electrician for more information

if you have questions about power loads, power requirements, and input ratings.

If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged

or corroded, do not use the outlet until it is replaced by a qualified electrician.

Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement.

Do not share an electrical outlet with other home or commercial appliances that draw large amounts of

electricity; otherwise, unstable voltage might damage your computer, data, or connected devices.

Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical outlet.

This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded outlet. If

you cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter or to replace

the outlet with one that enables this safety feature. Never overload an electrical outlet. The overall system

load should not exceed 80 percent of the branch circuit rating. Consult an electrician for more information

if you have questions about power loads and branch circuit ratings.

Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the

equipment. Do not fully extend power cords in a way that will stress the cords.

Be sure that the power outlet provides the correct voltage and current for the product you are installing.

Carefully connect and disconnect the equipment from the electrical outlet.

Do not connect or disconnect any external device cables other than Universal Serial Bus (USB) cables while

the computer power is on; otherwise, you might damage your computer. To avoid possible damage to

connected devices, wait at least five seconds after the computer is shut down to disconnect external devices.

Computers, power adapters, and many accessories can generate heat when turned on and when batteries

are charging. Always follow these basic precautions:

• Do not leave your computer, power adapter, or accessories in contact with your lap or any part of your

body for an extended period when the products are functioning or when the battery is charging. Your

computer, power adapter, and many accessories produce some heat during normal operation. Extended

contact with the body could cause discomfort or, potentially, a skin burn.

• Do not charge the battery or operate your computer, power adapter, or accessories near flammable

materials or in explosive environments.

• Ventilation slots, fans, and heat sinks are provided with the product for safety, comfort, and reliable

operation. These features might inadvertently become blocked by placing the product on a bed, sofa,

carpet, or other flexible surface. Never block, cover, or disable these features.
