Lenovo ThinkPad T61 User Manual

Chapter 2. Taking care of your ThinkPad 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.
Important tips
Be careful about where and how you work
v When your computer is turned on or the battery is charging, the base, the
palm rest, and some other parts may become hot. Avoid keeping your
hands, your lap, or any other part of your body in contact with a hot
section of the computer for any extended length of time. When you use the
keyboard, avoid keeping your palms on the palm rest for a prolonged
period of time.
Your computer generates some heat during normal operation. The amount
of heat depends on the amount of system activity and the battery charge
level. Extended contact with your body, even through clothing, could cause
discomfort or even a skin burn. Periodically take breaks from using the
keyboard by lifting your hands from the palm rest; and be careful not to
use the keyboard for any extended length of time.
v 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.
v 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 machine 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.
v Place liquids away from your computer to avoid spills, and keep your
computer away from water (to avoid the danger of electrical shock).
v Store packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
v Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm or 5 in).
v Avoid subjecting your computer to extreme temperatures (below 5°C/41°F
or above 35°C/95°F).
