      Handling your ThinkPad computer
      Notebook computers are precision machines that require a bit of careful handling. Though the ThinkPad computer is designed and tested to be a durable notebook computer that functions reliably in normal work environments, you need to use some common sense in handling it.

      ThinkPad don'ts
      • Do not subject your computer to physical punishment, such as dropping or bumping.
      • Do not place heavy objects on your computer.
      • Do not spill or allow liquids into your computer.
      • Do not pack your computer in a tightly packed suitcase or bag. The compression might cause internal damage.
      • Do not disassemble your computer. Only an authorized ThinkPad repair person should disassemble and repair your computer.
      • Do not scratch, twist, hit, or push the surface of your computer display.
      • Do not place any objects between the display and keyboard or under the keyboard.
      • Do not pick up or hold your computer by the display. When picking up your open computer, hold it by the bottom (keyboard) half.
      • Do not turn your computer over while the AC Adapter is plugged in. This could break the adapter plug.
      • Do not store your computer where the temperature is below 5° C or above 35° C (41° F and 95° F).
      • Do not place your computer closer than 13 cm (5 in.) from any electrical appliance that generates a strong magnetic field, such as a motor, magnet, TV, refrigerator, or large audio speakers.
      • Do not hard-mount your computer in a vehicle or anywhere that it is subject to strong vibration. See the section on ruggedized mobile computers for information a more appropriate model for demanding applications.
      • Do not crush, drop, or physically punish the external or removable hard drive, diskette drive, or CD-ROM drive when it is outside of your computer.
      • Do not press on the middle part of the diskette drive.
      • Do not insert a diskette at an angle. Not inserting the diskette straight into the drive can damage the drive.
      • Do not place more than one label on a diskette. Multiple or loose labels can detach or tear and then lodge in the drive.
      • Do not touch the lens on the CD-ROM tray. You should hold the compact disc by the edges and not touch its surface.
      • Do not connect a PBX (private branch exchange) or other digital telephone extension line. Your computer can use only a public-switched telephone network (PSTN). Use of a phone line other than PSTN can damage your modem. If you are not sure which kind of phone line you are using, contact your telephone company. Many hotels or office buildings use digital telephone extension lines, so check before connecting the telephone cable in such places.

      ThinkPad do's
      • Replace the plastic bezel faces (if supplied) when you exchange drives in your computer.
      • Store your external and removable hard drive, diskette drive, and CD-ROM drives in the appropriate container or packaging when not in use.
      • When installing your hard drive, diskette drive, or CD-ROM drive, apply pressure only where indicated on the device.
      • When installing the CD-ROM or diskette drive into the Ultrabay, make sure the AC Adapter is disconnected from your computer.
      • Choose a quality carrying case that will provide excellent protection for your computing investment.
      • Treat your computer like a precision piece of electronic machinery.
      • Register your ThinkPad products with Lenovo. This can help authorities return your computer to you if it is lost or stolen. Registering your computer also enables Lenovo to notify you about possible upgrades.
      • Retain and store packing materials safely out of reach of children to prevent the risk of suffocation from plastic bags.
      • Check the Think support pages at /ContentResources/Migrated Assets/think/support periodically to get current information about your computer.

      Cleaning your computer

      Isopropyl Alcohol is a flammable liquid. Do not use this cleaner near an exposed flame or when the system is on.

      You should occasionally clean your computer as follows:

      • Use a soft lint-free cloth moistened with non-alkaline detergent to wipe the exterior of the computer.
      • Don't spray cleaner directly on the display or keyboard.
      • Gently wipe the LCD with a dry, soft lint-free cloth. If a stain remains, moisten the cloth with LCD cleaner and wipe the stain again. Be sure to dry the LCD before closing it.
        Note: A 50-50 mixture of isopropyl alcohol and water or water alone may be used as a LCD cleaner to moisten your cloth. Antistatic LCD cleaning cloths and Kim Wipes are also acceptable alternatives.

      Carrying your computer
      When carrying your computer, follow these instructions to prevent possible damage to your computer and data:
      • Remove any media from the CD-ROM drive or diskette drive.
      • Turn off all attached devices.
      • Turn off the computer and close the LCD.
      • Unplug all external cables and cords connected to your computer.
      • Make sure all computer doors and covers are closed.
      • Use a quality carrying case that provides adequate cushion and protection.

      Extending your battery life
      The amount of battery power consumed by your computer depends on such conditions as how often you use it, the operating temperature, and the period in storage (if unused). The following tips can help you to extend the life of your battery:
      • If your battery is brand new and you are charging it for the first time, it might not become fully charged due to the characteristics of the chemicals in the cell. To maximize performance, ensure that all chemicals in the battery are fully activated by cycling the battery (fully charge, then fully discharge) three times. This procedure is also recommended if you stored the battery for a few months.
      • Do not charge the battery pack until all of its power is used. Recharging a battery pack that is not completely discharged can shorten battery life.
      • Once you start charging the battery pack, do not use it until it is fully charged.
      • Whenever possible, use the ThinkPad battery power-saving modes:
        • Standby: The LCD and the hard drive are turned off.
        • Suspend: All tasks are stopped and stored in memory to save power.
        • Hibernation: All tasks are stopped. The memory data and the current status of the computer are stored in the hard drive; then the power is turned off.
      • Decrease the LCD brightness.
      • Use Advanced Power Management (APM). Each operating system comes with its own APM.
      • Stop the power supply to a serial device if it is not in use.
      • Remove the battery pack and keep it in a cool place if you will not be using the computer for a long period
