Lenovo B450 User Manual page 75

- When you install a static-sensitive option or CRU, touch the static-
protective package containing the part to a metal expansion-slot cover
or other unpainted metal surface on the computer for at least two
seconds. This reduces static electricity in the package and your body.
- Whenever possible, remove the static-sensitive part from the static-
protective packaging and install the part without setting it down.
When this is not possible, place the static-protective packaging on a
smooth, level surface and place the part on it.
- Do not place the part on the computer cover or other metal surface.
Be gentle with your computer
• Avoid placing any objects (including paper) between the display and the
keyboard or under the keyboard.
• Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy
objects on your computer, display, or external devices.
• Avoid turning the display beyond 150°.
Carry your computer properly
• Before moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
• Be sure your computer is in sleep or hibernation mode, or turned off,
before moving it. This will prevent damage to the hard disk drive and
data loss.
