Abstract
When the main body of personal computer for example stays in the active state, the signal from the signal terminal is always on a low level. The discharge to the main body of personal computer continues and hence the power supply is prevented from being forced to be turned off so far as the total terminal voltage of all the unit batteries does not fall below 11.2 V even if some of the unit batteries show a terminal voltage of less than 2.5 V, thereby keeping the switching element on. Accordingly, the occurrence of defectives on hard disk or the like due to forced disconnection of power supply can be prevented as much as possible.
