ThinkPad Don'ts

• Do not leave the base of your computer in contact with your lap or any part of your body for an extended period when the computer is functioning or when the battery is charging. You computer dissipates some heat during normal operation. Extended contact to the skin could cause discomfort or, eventually, a skin burn.
• 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 use your computer in or near water (to avoid the danger of electrical shock).
• 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 IBM 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 modify or tape the latches to keep the display open or closed.
• Do no turn your computer over while the AC Adapter is plugged in. This could break the adapter plug.
• Do not use or 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 on a more appropriate model for demanding applications.
• 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 or DVD-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.
• Do not place an active cellular phone on the computer.
