Sharp PC-MM1 User Manual
Your computer is integrated with a magnet on the right side of the display.
Be sure to keep the magnetic cards or floppy disks away from the right side of your
computer. Otherwise the data on the cards or floppy disks may be erased.
This computer has a sensor on the right side of the keyboard which responses to the
magnet. If you bring the magnet near the right side of the keyboard, the backlight is
turned off, and the system may enter the standby or the hibernate mode depending on
the setting. (See Chapter 3.)
