    • The control unit of a computer system comprises a first storing device for holding written data while the power is on, a second storing device for holding the written data, even when the power is off and a power-off preserving device for terminating power to the system after transferring the data held in the first storing device to the second storing device. The control system can be utilized to only store the effective contents of the operating data to thereby enable data reconstruction upon resumption of power. The control device can interface with a window system processing device which can enable the refreshing of graphic display information upon resumption of power. The second storing device may have limited memory capacity and the operator can be informed of its capacity prior to a final shut-off of power. The control unit can further identify those programs that are not capable of being restored to their original condition and accordingly canceling any program execution when such a condition is judged.
    • 计算机系统的控制单元包括用于在电源接通时保持写入数据的第一存储装置,即使电源关闭时用于保存写入数据的第二存储装置和用于将电力终止于电源的断电保持装置 系统将保存在第一存储装置中的数据传送到第二存储装置。 控制系统可以用于仅存储操作数据的有效内容,从而使得在恢复电力时能够进行数据重建。 控制装置可以与窗口系统处理装置连接,该窗口系统处理装置能够在恢复电力时使图形显示信息更新。 第二存储装置可能具有有限的存储器容量,并且可以在最终关闭电源之前通知操作者其容量。 控制单元可以进一步识别那些不能恢复到其原始状态的程序,从而在判断出这种状况时取消任何程序的执行。
