Air circulation Your computer and monitor produce heat. The computer has fans that pull in fresh air and force out hot air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage. Place the computer and monitor so that nothing blocks the air vents; usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is not blowing on someone else. Electrical outlets and cable lengths The location of electrical outlets and the length of power cords and cables that connect to the monitor, printer, and other devices might determine the final placement of your computer. When arranging your workspace: Avoid the use of extension cords. Whenever possible, plug the computer power cord directly into an electrical outlet. Keep power cords and cables neatly routed away from walkways and other areas where they might be kicked accidentally. For more information about power cords, see "Power cord notice" on page 165. Connecting computer cables Read the following before connecting cables: Connect all device cables before plugging any power cords into an electrical outlet. Connect the monitor cable to the monitor if it is not already attached. If your computer comes with a ScrollPoint® mouse, the first time you start up your computer your mouse ScrollPoint function might not work. The ScrollPoint mouse function will be enabled after you shut down and restart your computer. Connect the power cords to the computer, monitor, and other devices first before plugging them into an electrical outlet. In some circumstances, the computer might not turn off immediately when you press the power switch. If this happens, hold the power switch down for 5 to 10 seconds until the computer turns off.
