Introduction Selecting a place to work 41 Never place a heavy object on the computer and be careful not to drop a heavy object onto the computer. It could damage the computer or cause system failure. ❖ Never turn off the computer if a drive light indicates a drive is active. Turning off the computer while it is reading from or writing to a disk or flash media may damage the disk or flash media, the drive, or both. ❖ Keep the computer and disks away from objects that generate strong magnetic fields, such as large stereo speakers. Information on some disks is stored magnetically. Placing a magnet too close to a disk can erase important files. ❖ Scan all new files for viruses. This precaution is especially important for files you receive via email or download from the Internet. Occasionally, even new programs you buy from a supplier may contain a computer virus. You need a special program to check for viruses. Important information on your computer's cooling fan Your computer may have a CPU cooling fan that cools the CPU by drawing outside air into the computer. Always make sure your computer and AC adaptor have adequate ventilation and are protected from overheating when the power is turned on or when an AC adaptor is connected to a power outlet (even if your computer is in Sleep mode). In this condition, observe the following: ❖ Never cover your computer or AC adaptor with any object. ❖ Never place your computer or AC adaptor near a heat source, such as an electric blanket or heater. ❖ Never cover or block the air vents including those located at the base of the computer. ❖ Using your computer on a carpet or other soft material can block the vents located at the base of the computer. Overheating your computer or AC adaptor could cause system failure, computer or AC adaptor damage or a fire, possibly resulting in serious injury.
