Caring for 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
Do not leave the base of your computer 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.
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 13cm/5 in).
v
Avoid subjecting your computer to extreme temperatures (below 5
°
C/41
°
F
or above 35
°
C/95
°
F).
Be gentle with your computer
v
Avoid placing any objects (including paper) between the display and the
keyboard or the palm rest.
v
Do not drop, bump, scratch, twist, hit, vibrate, push or place heavy objects
on your computer, display, or external devices.
v
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.
Carry your computer properly
v
Before moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
v
Be sure your computer is in standby or hibernation mode, or turned off,
before moving it. This will prevent damage to the hard disk drive and data
loss.
v
When picking up your open computer, hold it by the bottom. Do not pick
up or hold your computer by the display.
