Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, the method for controlling a battery to enter a ship mode according to the present embodiment includes:
step 101, in the BIOS operation stage, the embedded controller detects whether there is a shortcut key input.
The designated shortcut key may be arbitrarily designated in advance through the embedded controller, and may specifically be one key or a combination of multiple keys, which is not limited specifically.
Generally, the BIOS runs in the following three phases:
a first stage, Power On Self Test (POST for short) for detecting hardware when the electronic device is just powered On; the general complete power-on self-test includes testing CPU, 640K basic memory, more than 1M extended memory, ROM, mainboard, CMOS memory, serial-parallel port, display card, soft and hard disk system and keyboard, once the problem is found in the self-test, the system will give prompt message or alarm.
The second stage, initialization, including creating interrupt vector, setting register, initializing and detecting some external devices, etc., wherein the important part is BIOS setting, mainly setting some parameters for hardware, reading these parameters when the device is started, comparing with the actual hardware setting, if not, it will affect the system start.
And a third stage, a boot start stage, to boot the DOS or other operating system. The BIOS reads the boot record from the starting sector of the floppy or hard disk, if not found, it will display no boot device on the display, if found, it will transfer the control right of the computer to the boot record, the boot record will load the operating system into the computer, after the computer is successfully started, this part of the BIOS task is completed.
In practical application, a user can input a specified shortcut key at any stage in the running process of the BIOS, and the purpose of controlling the battery to enter the ship mode can be achieved.
102, if the input of a specified shortcut key is detected, the embedded controller sends a power saving mode trigger instruction to a battery control chip, and the battery control chip controls a battery to enter a ship mode after receiving the power saving mode trigger instruction; meanwhile, the embedded controller controls the electronic equipment to carry out shutdown processing.
After the electronic equipment is shut down, when the external power adapter is detected, the embedded controller can control the battery to exit the transportation power-saving mode through the battery control chip, and at the moment, the electronic equipment can be normally turned on and off.
And 103, if the input of the appointed shortcut key is not detected, controlling the electronic equipment to enter an operating system after the BIOS operation is finished.
In the process, before entering an operating system, a user can input a designated shortcut key at any time, and the embedded controller immediately sends a power saving mode triggering instruction to the battery control chip after detecting the shortcut key so as to trigger the battery to enter a ship mode; and when the user does not input the appointed shortcut key, directly entering the operating system after the BIOS operation is finished according to the conventional flow. Compared with the existing mode of running a specific tool under an operating system and sending a trigger instruction to the battery control chip through the specific tool, the method and the device do not need to develop the specific tool, reduce development cost and simplify user operation.
Example two
Referring to fig. 2, the method for controlling a battery to enter a transportation power saving mode according to the embodiment includes:
step 201, in the BIOS operation phase, the embedded controller detects whether a specified shortcut key is input, sets a preset flag bit if the specified shortcut key is detected, and does not process the flag bit if the specified shortcut key is not detected.
The flag bit is arranged at a specified position in a memory in the embedded controller, and the preset value of the flag bit is designated as a flag for triggering the battery to enter the ship mode.
Step 202, the BIOS detects whether the flag bit is set in real time, and if it is detected that the flag bit is set, continues to perform step 203; if the flag bit is not detected to be set, step 205 is executed after the BIOS operation is finished.
Step 203, the BIOS prompts the user to determine whether the battery needs to be controlled to enter the ship mode; if the user determines that the request is needed, continuing to execute step 204; if the user determines that it is not needed, step 205 is executed after the BIOS operation is finished.
For example, when the user selects to press the Enter key, the user is determined to determine that the battery needs to be controlled to Enter the ship mode; when the user selects to press the Esc key, the user is deemed to determine that the battery does not need to be controlled to enter the ship mode.
Step 204, the BIOS sends a power saving mode trigger instruction to the embedded controller, and the battery control chip controls the battery to enter a ship mode after receiving the power saving mode trigger instruction; meanwhile, the embedded controller controls the electronic equipment to carry out shutdown processing.
And step 205, after the running of the BIOS is finished, controlling the electronic equipment to enter an operating system.
Different from the manner in which the embedded controller immediately triggers the battery to enter the ship mode when detecting that the designated shortcut key is input, in the second embodiment, before triggering the battery to enter the ship mode, the embedded controller sets a flag bit in an internal memory thereof to notify the BIOS to prompt the user, and after the user confirms to continue the next step, the BIOS notifies the embedded controller to trigger the battery to enter the ship mode. Therefore, misoperation of a user can be avoided, and the control accuracy is improved.
EXAMPLE III
The third embodiment provides an electronic device, which includes a BIOS, an embedded controller, a battery control chip, and a battery.
To achieve higher processing speed, the embedded controller may directly control the battery to enter the ship mode according to the input of a designated shortcut key.
At the moment, the embedded controller is specifically used for sending a power saving mode triggering instruction to the battery control chip when the input of the appointed shortcut key is detected;
and the battery control chip is specifically used for controlling the battery to enter a transportation power saving mode when receiving the power saving mode trigger instruction.
In addition, in order to avoid misoperation, the embedded controller can also control the battery to enter the ship mode after obtaining the confirmation instruction of the user.
At this time, the embedded controller is specifically configured to set a preset flag bit when detecting that a specified shortcut key is input, and is further configured to send a power saving mode trigger instruction to the battery control chip when receiving a notification of the BIOS;
the BIOS is specifically used for detecting whether the flag bit is set in real time, prompting a user to determine whether the battery needs to be controlled to enter a transportation power saving mode when the flag bit is set, and informing the embedded controller after receiving a confirmation instruction of the user;
and the battery control chip is specifically used for controlling the battery to enter a transportation power saving mode when receiving the power saving mode trigger instruction.
It should be noted that the embedded controller is further configured to control the battery to exit the transportation power saving mode through the battery control chip when detecting the external power adapter, and at this time, the electronic device can be normally turned on and off.
