    摘要: The disclosure discloses a method for power-on control of a mobile terminal and a mobile terminal. The method includes: when a power-on detection flag bit in a mobile terminal is at a high level, judging whether there is an external power supply access event; if it is judged that there is an external power supply access event, and it is detected that the mobile terminal is in a power-off status currently, then triggering an external power supply power-on event, and setting the power-on detection flag bit to a high level; if it is judged that there is no external power supply access event, then judging whether there is a key-pressing event; and if it is judged that there is a key-pressing event, and it is determined that the key-pressing event is used for controlling to turn on the mobile terminal, then triggering a key-pressing power-on event, and setting the power-on detection flag bit to a high level. The technical solution of the disclosure proposes a specific implementation solution for supporting two types of power-on events using an existing power supply management chip.
