However, a few simple precautions taken when moving the computer will help ensure trouble-free operation. Make sure all disk activities are terminated before moving the computer. Disconnect the AC adapter and all peripherals before moving the computer. When carrying your computer, be sure to hold it securely so that it does not fall or hit anything.

If the computer's internal temperature rises to a certain level, the cooling fan is turned on or the processing speed is lowered. You can select whether to control the CPU temperature by turning on the fan first, then if necessary, lowering the CPU speed. Or, by lowering the CPU speed first, then if necessary, turning on the fan. When the CPU temperature falls to a normal range, the fan is turned off and the CPU operation returns to standard speed. If the CPU temperature reaches an unacceptably high level with either setting, the system automatically shuts down to prevent damage. Data in memory will be lost. User's Manual 4-25 The Keyboard Chapter 5 The Keyboard The number of keys on your keyboard depends on which country/region's keyboard layout your computer is configured with. There are four types of keys: typewriter keys, function keys, soft keys, and Windows special keys. Typewriter keys The typewriter keys, produce the uppercase and lowercase letters, numbers, punctuation marks, and special symbols that appear on the screen. There are some differences, however, between using a typewriter and using a computer keyboard: Letters and numbers produced in computer text vary in width. Spaces, which are created by a "space character, " may also vary depending on line justification and other factors. The lowercase l (el) and the number 1 (one) are not interchangeable on computers as they are on a typewriter. The CAPS LOCK function key locks only the alphabetic characters in uppercase while the shift lock on a typewriter places all keys in the shifted position. The SHIFT keys, the TAB key, and the BACK SPACE key perform the same function as their typewriter counterparts but also have special computer functions. Function keys: F1 . . . F9 The function keys, not to be confused with FN, are the 9 keys at the top of your keyboard. These keys are dark gray, but function differently from the other dark gray keys. User's Manual 5-1 The Keyboard F1 through F9 are called function keys because they execute programmed functions when pressed.

ROM: Read Only Memory: A nonvolatile memory chip manufactured to contain information that controls the computer's basic operation. [. . . ]
