Computer Usage Precautions
• When the computer is runnin , do not use a dust shield or dust cloth to cover the heat dissipation vents
on the top of the product to prevent hardware dama e.
• Never open the housin of non-repairable parts, such as the optical drive and power adapter.
DANGER
Opening the optical drive or power adapter housing can cause electric shock, laser radiation, or
even explosion.
• Do not drop, bump, scratch, twist, hit, vibrate, or push your computer unit, monitor, or external devices.
• If the computer you purchased has a wireless network card, this card may be incompatible with outdated
routers, causin connection failures. To solve this problem, we recommend you contact your router
manufacturer and request a firmware update.
• Lenovo is not responsible for third-party software and antivirus pro rams that use your computer’s
camera, microphone, or other multimedia devices to obtain private information (includin ima es or audio)
throu h Wi-Fi, Bluetooth, Ethernet, and other methods of communication.
Optical Mouse Usage Precautions
An optical mouse functions by emittin a stron red li ht throu h its LED, which is reflected by the desktop
surface and enters the sensor. The sensor senses micro texture chan es in the desktop surface to calculate
the direction and displacement of the mouse movement. Therefore, the reflective conditions of the desktop
have a si nificant influence on the performance of the optical mouse. The performance of the optical mouse
is de raded when used on the followin types of surfaces causin jitter, jumps, difficult movement, or even
complete lack of function:
• Surfaces that cannot reflect li ht diffusely: such as lass table tops, transparent table mats, and mirrors.
• Overly shiny surfaces: such as metal surfaces and laminated ma azine covers.
• Surfaces with stron directional textures: such as brushed metal surfaces, wood surfaces with strai ht
rain, and tatami mats.
• Surfaces that are uniform at the micron level: such as marble tabletops and artificial marble tabletops.
• Surfaces with pixel-level specifications and patterns: such as coordinate paper, screen-printed patterns,
and boards with artificial wood rain.
• Surfaces that are too dark or close to red: such as black or red desktops.
If your desk has one of the above surfaces, we recommend you take one of the followin measures to
improve your optical mouse performance:
• Place a piece of ordinary white paper that is not too smooth (and is not too shiny, like coated paper) on
your desktop to use as a mousepad.
