Taking care of your computer

Although your computer is designed to function reliably in normal work environments, you need to use

common sense in handling it. By following these important tips, you will get the most use and enjoyment

out of your computer.

Be careful about where and how you work

Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic

bags.
Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers

(within 13 cm or 5 inches).
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 puri ers, can 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, can increase the risk of ESD. Therefore, when using the computer

close to an appliance that can produce negative ions, give special attention to the following:

Avoid directly exposing your computer to the air from an appliance that can produce 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 signi cant electrostatic charge.

Be gentle with your computer

Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.
Your computer display is designed to be opened and used at an angle slightly greater than 90 degrees.

Do not open the display beyond 180 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.
When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by

the display.

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 drive, mSATA solid-state drive, 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 or the mSATA solid-state drive.
When replacing the hard disk drive, reattach the cover of the drive slot.
