Description
Technical field
The invention belongs to notebook systems to restart control technology field, and in particular to a kind of notebook based on EC microcontrollers
System reboot control method.
Background technology
EC（Embeded Controller, embedded controller）It is a kind of 16 microcontrollers.The electric-opening on notebook
During, EC controls the external equipments such as sequential and keyboard, fan, the charging indicator light of most of signal of interest.Work as notes
This access external power supply, whether under booting or off-mode, EC is all in operating status.EC is in notebook internal control
Play irreplaceable important function.
It is power-down rebooting that traditional notebook, which restarts mode,.When EC receives reset command, into restarting timing control section,
All electric signals drag down successively according to power-off sequential, and charging indicator light is gone out by bright turn, and screen backlight is dark by bright turn, notebook shape
State switches to shutdown, and after the delay of certain time length, electric signal is pulled up according to electrifying timing sequence successively, system state indicator and screen
Curtain backlight is lit, and notebook switches to open state, carries out system loads.This is restarted mode and pulls up electric signal drop-down again,
It extends system and restarts key to completing to restart the process of loading system, the power down phenomena impair such as screen backlight and indicator light from pressing
The experience of user, it is difficult to meet the requirement that user restarts notebook.This is in place of the deficiencies in the prior art.
Therefore, in view of the above-mentioned drawbacks in the prior art, provide design a kind of notebook system weight based on EC microcontrollers
Open control method；To solve the above technical problems, it is necessary.
Invention content
It is an object of the present invention to which in view of the above-mentioned drawbacks of the prior art, providing design one kind being based on EC microcontrollers
Notebook system restart control method, to solve the above technical problems.
To achieve the above object, the present invention provides following technical scheme：
A kind of notebook system based on EC microcontrollers restarts control method, for the content for the programming for restarting module completion
Including restarting function of movement, restarting action triggers function, restart writing and encapsulating for timing control function.Restart function of movement work
To restart the function for making process top layer, completely and uniquely control EC receives a series of actions after reset command, system
State change thus entrance complete, ensure reset command mistakenly change system other status informations, ensure that work(
The reliability of energy module.
It is increased newly in the system mode of original acquiescence and restarts state.The state for restarting action triggers function modification system is attached most importance to
Open state, restarting timing control function will foreclose to the control of nuclear power and screen signal, only in accordance with restart sequential drop-down and on
Draw the Restart Signal of several non-electrical.When pulling down part signal, due to millisecond being single for the control of power supply in EC main programs
Position carries out, and pulldown signal is not necessarily to delay operation, therefore newly-increased drop-down function is to realize in primary millisecond event to all non-
The drop-down motion action of electric signal finishes, and pull-up action retains the rhythm triggered according to millisecond event, realizes and prolongs to certain needs
When the normal upper pulling process of the signal that waits for.Restart action to complete system mode switching to booting, notebook normal load
Operating system.The design ensures to enter rebooting status after notebook receives Restart Signal, in the case of nuclear power not power down, complete
The components such as CPU, ICH, TCM are restarted, show as in appearance notebook screens backlight is not dark, system state indicator does not go out,
Operating system normal load.
Power function in the programming is write using the method successively encapsulated, newly-increased that system reboot state is determined
Justice ensure that program has excellent portable characteristic, EC milliseconds of event trigger mechanisms adapted on rhythm, it is ensured that EC management notes
The working efficiency of this power supply is maintained at higher level.
The beneficial effects of the present invention are after EC receives reset command, into holding function function is restarted, system mode is more
It is changed to restart state, pull-up and lower pulling is carried out according to existing sequential to the control signal of non-electrical according to the rhythm of action of millisecond event
Make, this process forecloses electric control signal and screen control signal, not power-down rebooting is realized, when shortening notebook is restarted
Between, optimize user experience.
In addition, design principle of the present invention is reliable, and it is simple in structure, there is very extensive application prospect.
It can be seen that compared with prior art, the present invention with substantive distinguishing features outstanding and significantly improving, implementation
Advantageous effect be also obvious.
Description of the drawings
Fig. 1 is the flow chart that a kind of notebook system based on EC microcontrollers provided by the invention restarts control method.
Fig. 2 is clock signal figure.
Specific implementation mode
The present invention will be described in detail below in conjunction with the accompanying drawings and by specific embodiment, and following embodiment is to the present invention
Explanation, and the invention is not limited in following implementation.
As illustrated in fig. 1 and 2, a kind of notebook system based on EC microcontrollers provided by the invention restarts control method, needle
The content of programming to restarting module completion includes restarting function of movement, restarting action triggers function, restart timing control
Function being write and encapsulating.Function of movement is restarted as the function for restarting action process top layer, controls completely and uniquely EC
A series of actions after reset command is received, thus entrance is completed for the change of the state of system, ensures reset command not mistakenly
Other status informations of modification system, ensure that the reliability of function module.
It is increased newly in the system mode of original acquiescence and restarts state.The state for restarting action triggers function modification system is attached most importance to
Open state, restarting timing control function will foreclose to the control of nuclear power and screen signal, only in accordance with restart sequential drop-down and on
Draw the Restart Signal of several non-electrical.When pulling down part signal, due to millisecond being single for the control of power supply in EC main programs
Position carries out, and pulldown signal is not necessarily to delay operation, therefore newly-increased drop-down function is to realize in primary millisecond event to all non-
The drop-down motion action of electric signal finishes, and pull-up action retains the rhythm triggered according to millisecond event, realizes and prolongs to certain needs
When the normal upper pulling process of the signal that waits for.Restart action to complete system mode switching to booting, notebook normal load
Operating system.The design ensures to enter rebooting status after notebook receives Restart Signal, in the case of nuclear power not power down, complete
The components such as CPU, ICH, TCM are restarted, show as in appearance notebook screens backlight is not dark, system state indicator does not go out,
Operating system normal load.
Disclosed above is only the preferred embodiment of the present invention, but the present invention is not limited to this, any this field
What technical staff can think does not have a creative variation, and without departing from the principles of the present invention made by several improvement and
Retouching, should all be within the scope of the present invention.
