Caring for Your Computer

Lenovo 3000 Y410 User Guide
• 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 from your body or clothing to the computer, it poses the same
risk of a computer malfunction.
Your computer is designed and manufactured to minimize any effects of
electrostatic charge. An electrostatic charge above a certain limit,
however, can increase the risk of ESD. Therefore, when using the
computer close to an appliance that can produce negative ions, give
special attention to the following:
– Avoid directly exposing your computer to the air from an appliance
that can produce negative ions.
– Keep your computer and peripherals as far as possible from such an
appliance.
– Wherever possible, ground your computer to facilitate safe
electrostatic discharge.
Note: Not all such appliances cause a significant electrostatic charge.
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.
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.
• When picking up your open computer, hold it by the bottom. Do not
pick up or hold your computer by the display.
• Use a quality carrying case that provides adequate cushion and
protection. Do not pack your computer in a tightly packed suitcase or
bag.
