PORTABLE TERMINAL EQUIPPED WITH A RECORDING MEDIUM

摘要

The invention relates to power saving in portable terminals ( 100 ) with recording media ( 200 ). Conventionally, there is the problem that a battery ( 104 ) in the portable terminal ( 100 ) may become exhausted and as a result the original function of the terminal cannot be performed. To solve this problem, when the remaining battery capacity is low, the invention controls power supply ( 108 ) to the recording media ( 200 ) and clock supply ( 110 ) to a CPU ( 202 ) in the recording media ( 200 ) so as to reduce power supplied to the recording media ( 200 )
