Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Prior to describing embodiments of the present invention, a related art will be understood.

The EC chip is a 16-bit singlechip, and a Flash memory (Flash) with certain capacity is arranged in the EC chip to store codes of the EC. The EC chip is a unique part in the notebook computer, and the use of the EC chip represents an important difference between the notebook computer and the common desktop computer.

The EC chip is no less in place in the system than the north-south bridge, and controls the time sequence of most important signals in the system starting process. In a notebook, the EC chip is typically left on whether the notebook is on or off, unless the battery and power Adapter (Adapter) are completely removed. In the power-off state, the EC chip generally keeps running all the time and waits for the power-on information of the user. After the computer is started, the EC chip is further used for controlling devices such as a keyboard controller, a charging indicator light, a fan and other various indicator lights, and even controlling the standby, dormant and other states of the system. Specifically, the function of an EC chip mainly includes three aspects: firstly, controlling the startup and shutdown time sequence; second, hardware health diagnostics and system health, such as controlling the speed of a fan and controlling the temperature of the system, and third, supporting input/output (I/O) devices, serial-parallel ports, and the like.

Currently, in some notebooks, the EC chip is allowed to be turned off for power saving, which causes the data stored in the RAM of the EC chip to be lost. For example, as shown in fig. 1, when a user needs to modify some hardware settings (such as a mode of a battery) of a notebook, first, the user performs an operation of modifying the hardware settings of the system through an interface provided by an Operating System (OS) (step 101); secondly, after receiving the operation of the user, the OS calls an AuditScript language (ASL) code (code), and directly stores data (battery mode information) corresponding to the modified system hardware setting into the RAM of the EC chip; in this case, when the EC chip is powered off, the data stored in the RAM of the EC chip is lost (step 103). Thus, when the EC chip is powered on again, since the data in the RAM of the EC chip is lost, the problem that the corresponding system hardware cannot be configured correctly occurs, for example: the mode of the battery cannot be configured, etc.

For the above problem, a solution is proposed: the method comprises the steps of storing relevant data into a Complementary Metal Oxide Semiconductor (CMOS) chip, and setting an EC chip RAM through the CMOS chip after the EC chip is powered off. Specifically, as shown in fig. 2, the implementation of the scheme mainly includes the following steps:

step 201: the user modifies the system hardware setting through the interface provided by the OS;

step 202: after receiving the modification operation of the user, the OS calls the ASLcode; here, the OS will also call the driver to effect the modification of the system hardware settings.

Step 203: the ASLcode stores the data corresponding to the modified system hardware setting into the CMOS chip;

step 204: the notebook computer is shut down or the system is automatically restarted, so that the EC chip is powered off;

step 205: after the EC chip is powered on, a Basic Input Output System (BIOS) reads data from the CMOS chip, and configures a RAM of the EC chip using the read data.

Here, after the system is started, the OS may also call ASLcode to read out data in the CMOS chip so as to configure a corresponding driver.

However, this implementation still has certain drawbacks: because the CMOS chip is still a volatile memory, when the notebook is powered off and the battery of the CMOS chip is removed, the data stored in the CMOS chip is still lost, and when the notebook is powered on and the EC is powered on, the data read out from the CMOS chip by the BIOS and the OS will be erroneous, so for the EC chip, because the BIOS configures the RAM of the EC chip using the data read from the CMOS chip, that is, the data is stored in the RAM of the EC chip, and the data stored in the RAM is incorrect data, the EC chip will have a problem that the corresponding system hardware cannot be configured correctly, for example: the mode of the battery cannot be configured, etc.

From the above analysis it follows that: if these configuration data relating to the underlying hardware are stored directly in the Read-only memory (ROM) of the EC chip, they will not be lost even if the EC chip is powered down (Real-time clock (RTC) disappears (lock)) because ROM is a non-volatile memory.

To implement the idea derived from the above analysis, it can only be implemented by modifying ASLcode. However, the conventional ASLcode is only used to match the OS to perform simple status check and I/O read/write on the underlying hardware, and if the ASLcode is allowed to directly store the configuration data of the underlying hardware into the ROM of the EC chip, the amount of code generated by modification is very large, so that the above idea is almost impossible to implement.

Based on this, in various embodiments of the invention: acquiring a first instruction; the first instruction is to indicate to detect a state of the first memory; responding to a first instruction, and judging whether the first memory is in a first state; the first state is indicative of a change in data stored in the first memory; when the judgment result represents that the first memory is in a first state, storing data in the first memory based on the first state into a second memory so as to enable the EC chip to configure a third memory by using the data in the second memory after being powered on; the first memory and the third memory are volatile memories; the second memory is a nonvolatile memory, so that data stored in the first memory is stored in the second memory, and the second memory is a nonvolatile memory, so that when the EC chip is powered on, the data in the second memory can be used for configuring the third memory, and thus, the data stored in the third memory (such as a RAM) can not be lost when the EC chip is powered off.

Example one

In order to solve the technical problem in the foregoing background, this embodiment provides an information processing method, which is applied to an electronic device, where the electronic device includes: the device comprises a first memory, a second memory and an EC chip; as shown in fig. 3, the method comprises the steps of:

step 301: acquiring a first instruction; the first instruction is to indicate to detect a state of the first memory;

the electronic device may be a notebook computer (laptop), a desktop computer (desktop), a server, a tablet computer (pad), a telephone (phone), or the like.

Step 302: responding to a first instruction, and judging whether the first memory is in a first state; the first state is indicative of a change in data stored in the first memory;

step 303: when the judgment result represents that the first memory is in a first state, storing data in the first memory based on the first state into the second memory so as to enable the EC chip to configure a third memory by using the data in the second memory after being powered on; the third memory is a volatile memory.

Here, in an embodiment, the first memory may be a CMOS chip; accordingly, the second memory may be a ROM of the EC chip; the third memory may be a RAM of the EC chip.

Wherein, since the EC chip has those functions described previously, the data stored to the third memory may be configuration data related to hardware settings of the underlying system of the electronic device, such as: configuration data of battery mode, etc.

Correspondingly, after the data configuration of the third memory is completed, the EC chip uses the configuration data stored in the RAM to realize the control of the corresponding hardware in the electronic device.

In one embodiment, the user sets the battery mode to the battery maintenance mode, and at this time, the CMOS chip stores configuration data of the battery maintenance mode; accordingly, the configuration data of the battery mode stored in the CMOS chip is changed, at this time, the configuration data of the battery maintenance mode stored in the CMOS chip is stored in the ROM of the EC chip, and after the EC chip is powered on (for example, the EC chip is powered off or restarted when the electronic device is powered off and powered on again), the RAM of the EC chip is configured by using the configuration data of the battery maintenance mode in the ROM, so that the EC chip realizes control over the battery mode in the electronic device by using the configuration data of the battery maintenance mode stored in the RAM.

In practical applications, steps 301 to 303 may be executed by the BIOS of the electronic device.

In the information processing method provided by the embodiment of the invention, when the data stored in the volatile first memory is changed, the data in the first memory is stored into the nonvolatile second memory, so that after the EC chip is powered down, although the data in the third memory (such as the RAM) is lost, after the EC chip is powered up again, the data in the second memory can be used for configuring the third memory of the EC chip, that is, the data in the second memory is stored into the third memory again, and thus, the data stored in the third memory is ensured not to be lost when the EC chip is powered down.

In addition, the scheme provided by the embodiment of the invention is simple, convenient and easy to realize, and only the corresponding code needs to be modified, and other irrelevant codes in hardware and electronic equipment do not need to be modified.

step 401: acquiring a first instruction; the first instruction is to indicate to detect a state of the first memory;

the electronic device may be a laptop, desktop, server, pad, phone, etc.

Step 402: responding to a first instruction, and periodically judging whether the first memory is in a first state; the first state is indicative of a change in data stored in the first memory;

here, since the state of the first memory may be changed periodically or irregularly, it may be required to periodically determine whether the first memory is in the first state, and when the determination result indicates that the first memory is in the first state, store the data in the first memory based on the first state into the second memory, so that the state of the first memory can be known in time, thereby ensuring the correctness of the data stored in the second memory.

Step 403: when the periodic judgment result indicates that the first memory is in a first state, storing data in the first memory based on the first state into the second memory so as to enable the EC chip to configure a third memory by using the data in the second memory after being powered on; the third memory is a volatile memory.

In one embodiment, the user periodically sets the battery mode to the battery maintenance mode, and at this time, the configuration data of the battery maintenance mode is periodically stored in the CMOS chip; accordingly, it is periodically detected that the configuration data of the battery mode stored in the CMOS chip is changed, at this time, the configuration data of the battery maintenance mode stored in the CMOS chip is periodically stored in the ROM of the EC chip, and after the EC chip is powered on (for example, the electronic device is powered off or restarted to power down the EC chip, and the EC chip is powered on again), the RAM of the EC chip is configured by using the configuration data of the battery maintenance mode in the ROM, so that the EC chip realizes control over the battery mode in the electronic device by using the configuration data of the battery maintenance mode stored in the RAM.

In practical application, the steps 401 to 403 may be executed by the BIOS of the electronic device, and meanwhile, a watchdog code of the EC chip may be modified to set a timer circuit for monitoring the operation of the BIOS and prompting the BIOS to periodically determine whether the first memory is in the first state; and executing corresponding operation according to the judgment result; specifically, when the judgment result represents that the first memory is in a first state, storing data in the first memory based on the first state to the second memory; and when the judgment result represents that the first memory is not in the first state, the storage operation is not executed.

the electronic device may be a laptop, desktop, server, pad, phone, etc.

Step 502: responding to a first instruction, and judging whether the first memory is in a first state or not by using a flag of the first memory; the first state is indicative of a change in data stored in the first memory;

the flag is a single-size-to-super-size flag used for recording the program state in the computer program, and whether the data stored in the first memory is changed or not can be known through the value of the flag in the first memory.

Step 503: when the judgment result represents that the first memory is in a first state, storing data in the first memory based on the first state into the second memory so as to enable the EC chip to configure a third memory by using the data in the second memory after being powered on; the third memory is a volatile memory.

In one embodiment, the user sets the battery mode to the battery maintenance mode, and at this time, the CMOS chip stores configuration data of the battery maintenance mode; accordingly, it can be known that the configuration data of the battery mode stored in the CMOS chip has changed through the flag value of the CMOS chip, at this time, the configuration data of the battery maintenance mode stored in the CMOS chip is stored in the ROM of the EC chip, and after the EC chip is powered on (for example, the electronic device is powered off or restarted to power down the EC chip, and the EC chip is powered on again), the configuration data of the battery maintenance mode in the ROM is used to configure the RAM of the EC chip, so that the EC chip uses the configuration data of the battery maintenance mode stored in the RAM to realize control over the battery mode in the electronic device.

In practical applications, steps 501-503 may be performed by the BIOS of the electronic device.

Wherein, since the EC chip has those functions described previously, the data stored to the third memory may be configuration data relating to the hardware settings of the underlying system of the electronic device, namely: the data stored to the third memory is: change data caused by a change in a system hardware setting of the electronic device, such as: configuration data of battery mode, etc.

In practical applications, steps 603-605 may be performed by the BIOS of the electronic device.
