ThinkPad® T23 Service and Troubleshooting Guide Note Before using this information and the product it supports, be sure to read the general information under "Appendix A. Important safety instructions" on page 39 and "Appendix B. Product warranties and notices" on page 45 . DANGER v To avoid electric shock hazard, connect and disconnect cables appropriately when installing, moving or opening the covers of this product or attached devices. Use the power cord with a properly grounded outlet. v 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. Your computer dissipates some heat during normal operation. This heat is a function of the level of system activity and battery charge level. Extended contact with your body, even through clothing, could cause discomfort or, eventually, a skin burn. v To reduce the risk of electric shock, do not use your computer in or near water. v To avoid electric shock, do not use your computer with the telephone cable connection during an electrical storm. Do not connect the cable to or disconnect it from the telephone outlet on the wall during an electrical storm. v Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags. v The battery pack contains a small amount of harmful substances. There is danger of an explosion if the battery pack is incorrectly replaced, exposed to fire or water, short-circuited or disassembled. Keep the battery pack away from children and do not put it in trash that is disposed of in landfills. v To reduce the risk of fire, use only No. 26 AWG or thicker telephone cable. v The fluorescent lamp in the LCD contains mercury. Do not put it in trash that is disposed of in landfills. Rough handling or dropping the computer can cause the LCD to break and the internal fluid to get into your eyes or on your hands. Immediately wash the affected areas with water. If symptoms persist, seek medical care. v Do not open the CD-ROM or DVD drive unit, as this might result in hazardous radiation exposure. v Avoid direct eye exposure with the laser beam contained in some drives.
