The invention relates to a terminal control method and device and a memory medium and belongs to the field of electronic technology application. The method comprises the steps of entering a sleep modeby closing at least two preset processes; obtaining predicted time when the sleep mode is completely quitted this time; and starting at least one process in the at least two processes to enter a state that the sleep mode is quitted slightly at preset time before the predicted time when the sleep mode is completely quitted this time. According to the embodiment of the invention, the predicted timewhen a terminal possibly quits the sleep mode completely, and the process closed in the sleep mode is started at the preset time before the predicted time, so when the terminal quits the sleep mode completely, excessive processes do not need to be started at the same time. The problem that in related technologies, the terminal is difficult to employ normally within short time due to the fact thata great number of processes are possibly started when the terminal quits the sleep mode is solved. The effect that the power consumption of the terminal in the sleep mode can be reduced and the terminal can be normally operated rapidly after the sleep mode is quitted can be achieved.
