Zusammenfassung:An automatic power-on control apparatus in a mobile terminal is provided to automatically turn on the power of a mobile terminal when a battery is installed at the mobile terminal without needing to push the power key in person. A battery(101) comprises two power terminals and a thermistor terminal(102), and the main body of a mobile terminal is connected with the battery(101) through a battery connector. At this moment, thermistor voltage is detected through the thermistor terminal(102). The detected thermistor voltage is used as an auto booting signal. The auto booting signal, more than 2.5V, detected through the thermistor terminal(102), activates a PMU(Power Management Unit)(104) so that auto booting for the mobile terminal can be executed.
