Machine state is held in RAM and, when placed in sleep mode, the computer cuts power to unneeded subsystems and places the RAM into a minimum power state, just sufficient to retain its data. Because of the large power saving, most laptops automatically enter this mode when the computer is running on batteries and the lid is closed.
Unlike many laptops that use a mechanical switch to detect when the lid is closed, in these systems the sensor is a magnetic reed switch that is located between the touchpad and the front edge of the laptop. There is a magnet that is located in the top lid above this switch, and when the lid is closed the magnet triggers the reed switch.
On the other hand, a system in sleep mode still consumes power to keep the data in the RAM, and thus cannot last indefinitely, as hibernation can. Detaching power from a system in sleep mode results in data loss, while cutting the power of a system in hibernation has no risk; the hibernated system can resume when and if the power is restored.
