Important safety information Safety guidelines ----------------------------------------------------------------------------Always observe the following precautions to reduce the risk of injury and property damage. Service and upgrades Do not attempt to service a product yourself unless instructed to do so by the customer support center or your documentation. Note: Some computer parts can be upgraded or replaced by the customer. Replacement parts approved for customer installation are referred to as Customer Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for customers to install options or replace CRUs. You must closely follow all instructions when installing or replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a product are zero. Before you remove the covers from a product equipped with an AC power cord, always make sure that the power is turned off and that the product is unplugged from any power source. Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer cool before opening the cover. Power cords and power adapters Use only the power cords and power adapters supplied by the product manufacturer. The power cord and power adapter are intended for use with this product only. They should never be used with any other product. The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. For other countries, the suitable types shall be used accordingly. Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that can cause the cord to fray, crack, or crimp. This can present a safety hazard. Always route power cords or any other cables so that they will not be walked on, tripped over, or pinched by objects. Safety and General Information Guide V1.0_en.book Page 4 Tuesday, August 2, 2011 3:04 PM Chapter 1. Important safety information Protect power cords and power adapters from liquids. For instance, do not leave your power cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can cause gradual corrosion of power cord terminals and/or the connector terminals on a power adapter, which can eventually result in overheating. Always connect power cords and signal cables in the correct order and ensure that all power cord connectors are securely and completely plugged into receptacles. Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such as deformed plastic) at the ac input or anywhere on the power adapter. Do not use any power cords where the electrical contacts on either end show signs of corrosion or overheating or where the power cord appears to have been damaged in any way. Extension cords and related devices Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use are rated to handle the electrical requirements of the product. Never overload these devices. If power strips are used, the load should not exceed the power strip input rating. Consult an electrician for more information if you have questions about power loads, power requirements, and input ratings. Plugs and outlets 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. Do not share an electrical outlet with other home or commercial appliances that draw large amounts of electricity; otherwise, unstable voltage might damage your computer, data, or attached devices.

Use and care Information Caring for your computer ---------------------------------------------------------------Though your computer is designed to function reliably in normal work environments, you need to use common sense in handling it. By following these important tips, you will get the most use and enjoyment out of your computer. Being careful about where and how you work. • Do not eat or smoke over your keyboard. Particles that fall into your keyboard can cause damage. • Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags. • Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (within 13 cm or 5 in). • Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F). • 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. 13 Safety and General Information Guide V1.0_en.book Page 14 Tuesday, August 2, 2011 3:04 PM Chapter 2. Use and care Information Notice of static-electricity When you handle options or CRUs, or perform any work inside the computer, take the following precautions to avoid static-electricity damage: - Limit your movement. Movement can cause static electricity to build up around you. - Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the edges. Never touch exposed circuitry. - Prevent others from touching components. - When you install a static-sensitive option or CRU, touch the staticprotective 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 staticprotective 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. Being 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 130°. 14 Safety and General Information Guide V1.0_en.book Page 15 Tuesday, August 2, 2011 3:04 PM Chapter 2. Use and care Information Carrying 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. For outdoor use • Backup your critical data before you take your computer outdoors. • Ensure that the battery is full. • Be sure to turn off the power and close the LCD well. • When you leave the computer in your car, place it on the back seat to avoid being insolated. • Carry the AC adapter and power cord with the computer. Handling storage media and drives properly • If your computer comes with an optical drive, do not touch the surface of a disc or the lens on the tray. • Wait until you hear the CD or DVD click into the center pivot of an optical drive before closing the tray. • When installing your hard disk, follow the instructions shipped with your hardware, and apply pressure only where needed on the device. 15 Safety and General Information Guide V1.0_en.book Page 16 Tuesday, August 2, 2011 3:04 PM Chapter 2. Use and care Information Data safety • Do not delete unknown files or change the name of files or directories that were not created by you; otherwise, your computer software might fail to work. • Be aware that accessing network resources can leave your computer vulnerable to computer viruses, hackers, spyware, and other malicious activities that might damage your computer, software, or data. • It is your responsibility to ensure that you have adequate protection in the form of firewalls, antivirus software, and anti-spyware software and keep this software up to date. Taking care in setting passwords • Remember your passwords. If you forget a supervisor or hard disk password, Lenovo authorized service providers will not reset it, and you might have to replace your system board or hard disk drive. Cleaning the cover of your computer Occasionally clean your computer as follows: 1 Prepare a mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or strong chemicals such as acid or alkaline). Use 5 parts water to 1 part detergent. 2 Absorb the diluted detergent into a sponge. 3 Squeeze excess liquid from the sponge. 4 Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip. 5 Wipe the surface to remove the detergent. 6 Rinse the sponge with clean running water. 7 Wipe the cover with the clean sponge. 8 Wipe the surface again with a dry, soft lint-free cloth. 9 Wait for the surface to dry completely and remove any cloth fibers from the computer surface. Note: Shut down the computer and then disconnect the power cord before cleaning the computer. 16 Safety and General Information Guide V1.0_en.book Page 17 Tuesday, August 2, 2011 3:04 PM Chapter 2. Use and care Information Cleaning your computer keyboard 1 Absorb some isopropyl rubbing alcohol on a soft, dust-free cloth. 2 Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time, the cloth may hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto or between the keys. 3 Allow to dry. 4 To remove any crumbs and dust from beneath the keys, you can use a camera blower with a brush or cool air from a hair drier. Note: Avoid spraying cleaner directly on the display or the keyboard. Cleaning your computer display 1 Gently wipe the display with a dry, soft lint-free cloth. If you see a scratchlike mark on your display, it might be a stain transferred from the keyboard when the cover was pressed from the outside. 2 Wipe or dust the stain gently with a soft, dry cloth. 3 If the stain remains, moisten a soft, lint-free cloth with water or a 50-50 mixture of isopropyl alcohol and water that does not contain impurities. 4 Wring out as much of the liquid as you can. 5 Wipe the display again; do not let any liquid drip into the computer. 6 Be sure to dry the display before closing it. 17 Safety and General Information Guide V1.0_en.book Page 18 Tuesday, August 2, 2011 3:04 PM Chapter 2.

Notices Notice on deleting data from your hard disk -----------------------As computers spread into every corner of life, they process more and more information. The data on your computer, some of it sensitive, is stored on a storage device called the hard disk. Before you dispose of, sell, or hand over your computer, you need to delete that data. Handing your computer over to someone else without deleting the loaded software, such as operating systems and application software, may even violate License Agreements. You are advised to check the terms and conditions of those Agreements. Deleting the data from the hard disk is not easy. There are methods that seem to delete the data: • Move the data to the recycle bin, and then choose the Empty recycle bin command. • Use the Delete command. • Format your hard disk, using the software for initializing it. • Using the preinstalled recovery program, bring the hard disk back to factory-ship state. These operations, however, only change the file allocation of the data; they do not delete the data itself. In other words, the data retrieval processing is disabled under an operating system such as Windows. The data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of special software for data recovery. There is a risk that people of bad faith may read and misuse the critical data on hard disks for unexpected purposes. To prevent the leakage of data, it becomes very important that you take responsibility for deleting all the data from the hard disk when you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the hard disk with a hammer, or magnetically by means of strong magnetic power, thus making the data unreadable. But we recommend that you make use of the software (payware) or service (pay service) specifically developed for the purpose. 39 Safety and General Information Guide V1.0_en.book Page 40 Tuesday, August 2, 2011 3:04 PM Trademarks Lenovo is the trademark of Lenovo in the United States, other countries, or both.
