Fig. 1 shows the inner structure block diagram according to computer system of the present invention.
Single-chip microcomputer (MCU) 100 has two I2C interfaces 101 and 102 (also can be the data-interface of other type), and I2C interface 101 links to each other with each sensor, and MCU 100 can directly obtain each temperature spot by I2C interface 101.I2C interface 102 links to each other with EC 300, and EC 300 is by the data (comprising temperature) of this I2C interface 102 visit MCU 100.MCU is by GPIO (general input and output pin) 103 control EC 300 reset (RESET).When the user pressed the start button, starting-up signal was directly imported MCU 100 and is linked to each other, and whether MCU 100 starts shooting by GPIO104 notice EC 300 again.Power supply by GPIO 105 control EC 300 of MCU 100 (EC power control module 500), and MCU 100 controls the heating (EC heating module 400) of EC 300 by GPIO 106.MCU 100 is by GPIO 107 control battery charge control modules 600.
The power switch of MCU 100 control EC 300 promptly, is controlled EC power supply control module 500.At low temperatures, in order to prevent EC 300 cisco unity malfunctions, MCU 100 can close the power supply of EC, and EC 300 is not worked.
Usually the EC of notebook is still in running order when shutdown, but its power consumption is very little, has only several milliwatts usually.But in the present invention, EC 300 less than power supply, does not therefore work when shutdown.After the shutdown, MCU 100 will close the power supply of EC 300, also need not EC heating module 400 is powered.
Influential to charging and discharging circuit when preventing under the low temperature EC power supply, when MCU 100 detected temperature and is lower than battery backed temperature, MCU 100 directly disconnected charging circuit by GPIO 107 control battery charge control modules.
In addition, MCU 100 has historical events record and analytic function.Because each notebook of producing, its low-temperature characteristics all is different, and MCU can write down and learn and add up the low-temperature characteristics of current notebook automatically.At current notebook, use best heat protocol.Simultaneously, each notebook in use its low-temperature characteristics can change along with using duration, and particularly, battery is along with using its cryogenic property of duration can become poorer.MCU utilizes its study and statistical function to regulate automatically at any time.In addition, MCU and BIOS (Basic Input or Output System (BIOS)) and EC keep in communication always, monitor the whole system operation state at any time, if note abnormalities deadlock, write down automatically and system is started shooting again.Simultaneously, recorded data can be used for follow-up analysis and research for engineering technical personnel.
Fig. 2 A shows the process flow diagram of the automatic temperature-adjusting establishing method of carrying out according to the present invention when Default Value.
At step S200, automatic temperature-adjusting is set beginning.At first, at step S202, design temperature is set to 0 ℃ (only as example, can according to circumstances be set to the temperature that computer chip can normally start).Then, at step S204, the operation of starting shooting normally, and judge, whether normal boot-strap at step S206.If system's normal boot-strap ("Yes" among the step S206) then at step S208, reduces by 1 ℃ or 0.5 ℃ with design temperature, and re-executes start operation (step S204).When system fails normal boot-strap ("No" among the step S206), at step S210, the temperature spot when once starting shooting successfully before the record, in this example, storage design temperature=current design temperature+1 ℃ or 0.5 ℃.Then, at step S212, judge whether the success ratio under this temperature meets the demands.If the start success ratio can not satisfy predefined requirement ("No" among the step S212), then return step S210, store higher design temperature, and whether rejudging success ratio under this temperature (for example per thousand starts, the frequency of failure is less than 5 times), (step S212) meets the demands.If meet the demands ("Yes" among the step S212),, finish to set processing according to automatic temperature-adjusting of the present invention then at step S220.
Present notebook, its temperature that guarantees operate as normal is all more than 0 ℃, but same design, the low-temperature characteristics of each that produce notebook is all different, since brilliant first production batch, encapsulation, the difference of production and assembly, some may-5 ℃ can operate as normal, some may can also operate as normal when-10 ℃ or-15 ℃.Like this, MCU can be at each notebook, since 0 ℃ of trial, goes to attempt start in the mode of successively decreasing of 1 ℃ or 0.5 ℃, if start shooting successfully, then continue to successively decrease, up to failure, the successful temperature spot of once starting shooting before the record then, and this temperature spot added up, after its start success ratio (for example per thousand starts, the frequency of failure is less than 5 times) reaches requirement, will be according to this temperature spot heating start.In use, MCU still ceaselessly adds up current heating-up temperature point, in case success ratio is lower than requirement, then increases progressively this temperature spot, circulates.
This scheme has a benefit, can greatly accelerate the starting up speed under the notebook low temperature, directly is heated to scheme that fixed temperature point start shooting then relatively with common, has optimization heat time heating time, automatically and adjustment at any time, guarantees that the low temperature success ratio of starting shooting is the highest.Simultaneously, this ruggedization under lower temperature scheme can also solve notebook along with the poor more problem of long more cryogenic effect service time, can solve some notebooks equally since the otherness of producing cause near the zero degree can't operate as normal quality problems.
