An electronic device and a system start method that reduce electric power consumption and improves convenience. A state check section detects that an information processing section is being booted and that a telephone conversation is being carried out by the use of an information processing section (portable telephone). When the state check section detects this state, the state check section outputs instructions to a clock control section to lower a frequency of an operation clock of a processing circuit included in the information processing section. When the clock control section accepts the instructions from the state check section to lower the frequency of the operation clock of the processing circuit, the clock control section lowers the frequency of the operation clock of the processing circuit. |
