Caring for your ThinkPad computer
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 under the keyboard.
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 135
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.
v Use a quality carrying case that provides adequate cushion and protection.
Do not pack your computer in a tightly packed suitcase or bag.
Handle storage media and drives properly
v If your computer comes with a diskette drive, avoid inserting diskettes at
an angle and attaching multiple or loose diskette labels, as these can lodge
in the drive.
v If your computer comes with a CD or DVD drive, do not touch the surface
of a CD or the lens on the CD or DVD tray.
v Wait until you hear the CD or DVD click into the center pivot of the CD or
DVD drive before closing the CD or DVD tray.
v When installing your hard disk, diskette, CD, or DVD drive, follow the
instructions shipped with your hardware, and apply pressure only where
needed on the device. See Access ThinkPad, your on-board help system, for
information on replacing your hard disk drive (open Access ThinkPad by
pressing the ThinkPad button).
Take care in setting passwords
v Remember your passwords. If you forget a supervisor or hard disk
password, IBM will not reset it, and you might have to replace your system
board or hard disk drive.
