Replacing the Battery Your computer has a special type of memory that maintains the date, time, and the settings for built-in features, such as serial- and parallel-port assignments (configuration). A battery keeps this information active when you turn off the computer. The battery requires no charging or maintenance throughout its life; however, no battery lasts forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An error message is displayed when you turn on the computer. Refer to "Lithium Battery Notice" on page vii of this publication and Installing Options in Your Personal Computer for information about replacing the battery. If you replace the original lithium battery with a heavy-metal battery or a battery with heavy-metal components, be aware of the following environmental consideration. Batteries and accumulators that contain heavy metals must not be disposed of with normal domestic waste. They will be taken back free of charge by the manufacturer, distributor, or representative, to be recycled or disposed of in a proper manner. Moving Your Computer Important Do not move the computer while it is on. Sudden movements, such as bumps, jerks, and drops, can cause the read/write head of the hard disk drive to bounce against the surface of the disk itself. This can cause loss of data and a variety of hard disk errors. Always turn off the computer before you move it. When the computer is off, the read/write head automatically parks itself over a nondata area of the hard disk. This process can help to prevent damage to the hard disk. CAUTION: Do not risk injury by moving or lifting the computer by yourself. Ask another person to help you. If your computer has a hard disk drive, take the following precautions: 1. Back up all files and data from the hard disk. Operating systems can vary in the way they perform backup procedures. Some operating systems save only data files, while others make copies of application Chapter 5. Taking Care of Your Computer 59
