Problems solved by technology

The problem with this method is to support fingerprint recognition and booting well. The dedicated chip requires a power management module that cannot be powered off.
However, when the mobile phone is turned off, the power management module will also consume extra power, and the user will also feel uneasy

Abstract

The invention provides a startup control method and electronic equipment. The startup control method is applied to the electronic equipment which comprises a biological characteristic recognition module. The method comprises the following steps: under the first state of the electronic equipment, generating a first electric potential according to a specific operation, wherein all power modules of the electronic equipment are under a non-power-supply state under the first state; through the first electric potential, starting a first power submodule in the power modules to bring convenience for supplying power to the biological characteristic recognition module so as to start the biological characteristic recognition module to operate; and when the biological characteristic recognition module recognizes that the user is an authorized user, starting a second power submodule in the power modules to bring convenience for supplying power to the electronic equipment so as to start the electronic equipment.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more particularly, to a startup control method and electronic equipment. Background technique [0002] Currently, for the safety of electronic devices, various biometric sensors have been used to control activation of electronic devices. Such biometric sensors include, for example, fingerprint sensors, retina / iris sensors, and the like. [0003] When electronic equipment is started, there are two common ways, one is to simply press the power-on button, and then start fingerprint recognition, and the power-on and fingerprint recognition are independent. The problem with this method is that it is usually impossible to control the startup through fingerprint identification, and it is not a real fingerprint identification boot solution, so it cannot give users a very good experience. [0004] Another way is to use a dedicated fingerprint recognition chip for fingerprint recognition a...
