Hardware maintenance Ä CAUTION: To reduce the risk of electric shock or damage to your computer: ■ Always disconnect the computer from the AC outlet and disconnect peripherals from the computer before attempting to clean the computer or any of its components. ■ Do not spray liquids on the computer keyboard, display, or drives, or allow liquids to drip onto them. Å WARNING: To avoid potential discomfort or burns, do not block the air vents or use the computer on your lap for extended periods. The computer is designed to run demanding applications at full power. As a result of increased power consumption, it is normal for the computer to feel warm or hot when used continuously. The computer complies with the user-accessible surface temperature limits defined by the International Standard for Safety of Information Technology Equipment (IEC 60950). Ä CAUTION: To prevent overheating, do not obstruct vents. Use the computer only on a hard, flat surface. Do not allow another hard surface, such as a printer, or a soft surface, such as pillows, thick rugs, or clothing, to block the airflow. 2 Routine Care
