Operating Basics Heat dispersal To protect from overheating, the CPU has an internal temperature sensor. 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. Use the Cooling Method item of the Power Save Mode window in TOSHIBA Power Saver. Maximum Performance Turn on the fan first, then if necessary, lower the CPU processing speed. Performance Use a combination of the fan and lowering the CPU processing speed. Battery optimised Lower the CPU processing speed first, then if necessary turn 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. The CPU cooling fan on the underside of your computer cools the CPU by drawing outside air into the computer. To prevent possible overheating of the CPU, make sure the cooling fan's air intake is not blocked. The fan draws in air by creating a vacuum. If the fan is blocked, it could cause the CPU to run at a lower performance level or cause the computer to shut down. Loose items such as notebook and tissue paper, plastic wrappers, or other similar materials can block the air intake, preventing air from reaching the CPU. Do not use the computer on surfaces with objects that can be drawn in by the cooling fan. Satellite Pro A10 Series 4-23
