Method for starting up device and device

A device, comprising:

• a power button;
• a fingerprint sensor integrated with the power button;
• a first microcontroller coupled to the power button and the fingerprint sensor;
• and
• a memory coupled to the first microcontroller and storing instructions that, when executed by the first microcontroller, cause the first microcontroller to be configured to:
• detect a touch operation from a user on the power button;
• obtain, in response to the touch operation, fingerprint information from the fingerprint sensor;
• save, by the first microcontroller coupled to the fingerprint sensor, the obtained fingerprint information;
• detect, by the first microcontroller, whether the power button is pressed within a first preset duration, wherein the first preset duration starts when a microcontroller coupled to the fingerprint sensor saves the fingerprint information;
• delete, by the first microcontroller, the saved fingerprint information in response to detecting that the power button is not pressed within the first preset duration;
• retain the saved fingerprint information in response to detecting that the power button is pressed within the first preset duration;
• in response to detecting, by a second microcontroller, that the power button is pressed:
• triggering power-on a central processing unit (CPU) of the device;
• loading a fingerprint drive of the device;
• and
• transmitting a fingerprint authentication request from the fingerprint drive of the device to the first microcontroller;
• and
• when the fingerprint information is retained:
• in response to not obtaining, by the first microcontroller, the fingerprint authentication request within a second preset duration, deleting the saved fingerprint information, wherein the second preset duration begins when the fingerprint information is saved;
• and
• in response to obtaining, by the first microcontroller, the fingerprint authentication request within the second preset duration, the instructions further cause the first microcontroller to be configured to:
• obtain, by the fingerprint drive, previously enrolled fingerprint information;
• receive, by the fingerprint drive from the first microcontroller, the saved fingerprint information;
• perform, by the fingerprint drive, fingerprint authentication on the saved fingerprint information using the enrolled fingerprint information to obtain an authentication result;
• obtain, by an operating system of the device, the authentication result from the fingerprint drive;
• and
• log the user into the operating system and displaying an operating system desktop when the authentication result indicates that fingerprint authentication succeeds.
