PURPOSE:To suppress current consumption in the data retaining operation of computer. CONSTITUTION:A computer, executing data retaining operation when a main switch 15 is turned OFF, comprises a high current first regulator 18, a low current second regulator 19, and a watchdog circuit 25 delivering a reset signal to the computer 10, wherein a current is fed from the first regulator 18 to the computer when the computer 10 executes various operations. When the computer 10 performs data retaining operation, power is fed to the computer only from the second regulator 19 and when the main switch 15 in turned OFF, a reset signal line between the computer 10 and the watchdog circuit 26 is interrupted and a transition is made fot the computer 10 to stop mode operation in a short time. |
