• Keep your computer more than 13 cm or 5 inches away from magnets, activated cellular phones,

electrical applicances, or speakers.

• Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F).

• Some appliances, such as certain portable desktop fans or air purifiers, produce negative ions. If a

computer is close to such an appliance, and is exposed for an extended time to air containing negative
ions, it might become electrostatically charged. Such a charge might be discharged through your hands
when you touch the keyboard or other parts of the computer, or through connectors on I/O devices
connected to it. Even though this kind of electrostatic discharge (ESD) is the opposite of a discharge from
your body or clothing to the computer, it poses the same risk of a computer malfunction.

Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic
charge above a certain limit, however, increases the risk of ESD. Therefore, when using the computer close
to an appliance that produces negative ions, give special attention to the following:

• Avoid directly exposing your computer to the air from an appliance that produces negative ions.

• Keep your computer and peripherals as far as possible from such an appliance.

• Wherever possible, ground your computer to facilitate safe electrostatic discharge.

Note: Not all such appliances cause a significant electrostatic charge.

Be gentle with your computer

• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.

• Do not open the display beyond 135 degrees, as this might damage the computer hinge.

• Do not turn your computer over while the ac power adapter is plugged in. This could break the adapter

plug.

Carry your computer properly

• Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect

cords and cables.

• Before moving your computer, ensure that it is in sleep or hibernation mode, or turned off. This prevents

damage to the hard disk drive and avoids data loss.

• When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by

the display.

• Use a quality carrying case that provides adequate cushion and protection. Do not pack your computer in

a tightly packed suitcase or bag.

For outdoor use

• Back up your critical data before you take your computer outdoors.

• Ensure that the battery is fully charged.

• Be sure to turn off the power and close the LCD when not in use.

• When you leave the computer in your car, place it on the back seat to avoid being insolated.

• Carry the ac power adapter and power cord with the computer.

Handle storage media and drives properly

• If your computer comes with an optical drive, do not touch the surface of a disc or the lens on the tray.

• Wait until you hear the CD or DVD click into the center pivot of the drive before closing the tray.

• When installing the hard disk drives or optical drives, follow the instructions shipped with your hardware,

and apply pressure only where needed on the device.

• Turn off your computer if you are replacing the hard disk drive.
