Important safety information Note: Read the important safety information first. Read this first This information can help you safely use your notebook computer. Follow and retain all information included with your computer. The information in this document does not alter the terms of your purchase agreement or the Lenovo Limited Warranty. For more information, see "Warranty Information" in the Safety and Warranty Guide that comes with your computer. Customer safety is important.
Protect yourself from the heat generated by the ac power adapter. When the ac power adapter is connected to an electrical outlet and your computer, it generates heat. Extended contact with your body, even through clothing, may cause a skin burn. • Do not place the ac power adapter in contact with any part of your body while it is in use. • Never use it to warm your body. Prevent your computer from getting wet. To avoid spills and the danger of electrical shock, keep liquids away from your computer.
Handle your computer gently. Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on your computer, display, or external devices. Carry your computer carefully. • Use a quality carrying case that provides adequate cushioning and protection. • Do not pack your computer in a tightly packed suitcase or bag. • Before putting your computer in a carrying case, make sure that it is off, in sleep mode, or in hibernation mode.
• Signs of overheating, smoke, sparks, or fire. • Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign substances on the battery. • A cracking, hissing or popping sound, or strong odor that comes from the product. • Signs that liquid has been spilled or an object has fallen onto the computer product or the power adapter. • The computer product or power adapter has been exposed to water. • The product has been dropped or damaged in any way.
Power adapters DANGER Use only the power adapters supplied by the product manufacturer. Never wrap a power adapter cable around a power adapter or other object. Doing so can stress the cord in ways that can cause the power adapter cable to fray, crack, or crimp. This can present a safety hazard. Always route the power adapter cable so that they will not be walked on, tripped over, or pinched by objects. Protect power adapters from liquids.
Plugs and outlets DANGER If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged or corroded, do not use the outlet until it is replaced by a qualified electrician. Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement.
External devices CAUTION: Do not connect or disconnect any external device cables other than Universal Serial Bus (USB) and 1394 cables while the computer power is on; otherwise, you might damage your computer. To avoid possible damage to attached devices, wait at least five seconds after the computer is shut down to disconnect external devices.
Notice for built-in rechargeable battery DANGER Do not attempt to remove or replace the built-in rechargeable battery. Replacement of the battery must be done by a Lenovo-authorized repair facility or technician. Only recharge the battery strictly according to instructions included in the product documentation. The Lenovo-authorized repair facilities or technicians recycle Lenovo batteries according to local laws and regulations.
Heat and product ventilation DANGER Computers, ac power adapters, and many accessories can generate heat when turned on and when batteries are charging. Notebook computers can generate a significant amount of heat due to their compact size. Always follow these basic precautions: • When your computer is turned on or the battery is charging, the base, the palm rest, and some other parts may become hot.
Electrical current safety information DANGER Electric current from power, telephone, and communication cables is hazardous. To avoid a shock hazard: • Do not use your computer during a lightning storm. • Do not connect or disconnect any cables or perform installation, maintenance, or reconfiguration of this product during an electrical storm. • Connect power adapter to a properly wired and grounded electrical outlet. • Connect to properly wired outlets any equipment that will be attached to this product.
Note: For products with mercury-containing fluorescent lamps (for example, non-LED), the fluorescent lamp in the liquid crystal display (LCD) contains mercury; dispose of according to local, state, or federal laws. Using headphones or earphones CAUTION: Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the equalizer to maximum increases the earphone and headphone output voltage and the sound pressure level.
