Caring Your Computer

Though 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
Do not leave the base of your computer, or any other part that becomes hot during
operation, in contact with your lap or any part of your body for an extended period
when the computer is functioning or when the battery is charging. Your computer
dissipates some heat during normal operation. This heat is a function of the level of
system activity and battery charge level. Extended contact with your body, even
through clothing, could cause discomfort or, eventually, a skin burn.
When the AC adapter is connected to an electrical outlet and your computer, it
generates heat. Do not place the adapter in contact with any part of your body while
using it. Never use the AC adapter to warm your body. Extended contact with your
body, even through clothing, may cause a skin burn.
Route the cables of an AC adapter, a mouse, a keyboard, a printer, or any other
electronic device, or communication lines, so that they cannot be walked on, tripped
over, pinched by your computer or other objects, or in any way subjected to treatment
that could disturb the operation of your computer. Applying strong force to the cables
may damage or break them.
Place liquids away from your computer to avoid spills, and keep your computer away
from water (to avoid the danger of electrical shock).
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 in).
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, 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 may become electrostatically charged.
Such a charge may 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
