The embodiment of the invention has disclosed the computer apparatus of a kind of automatic temperature-reduction protective and this method of use.
The automatic temperature-reduction protective of the embodiment of the invention utilizes a keyboard controller to set up monitoring temperature mechanism and framework in computer apparatus inside.ROM-BIOS is in this computer apparatus inner setting different temperature threshold value and the behavior that surpasses temperature threshold value.When this starting up for computer, this ROM-BIOS is set a temperature threshold value earlier, and send this temperature threshold value to this keyboard controller, so that the temperature of this keyboard controller monitoring central processing unit, and judged whether to surpass or be lower than this temperature threshold value.The temperature of detecting this central processing unit when this keyboard controller surpasses or when being lower than the temperature threshold value of this setting, send system control and interrupt (SCI) or a system management interrupt (System Management Interrupt, abbreviating SMI as) incident gives this ROM-BIOS, so that being carried out, this central processing unit quickens or the operation of cooling.
Fig. 1 shows the flow chart of steps of the automatic temperature-reduction protective of the embodiment of the invention.This automatic temperature-reduction protective is applicable to a computer apparatus, and this computer apparatus comprises an embedded controller (for example, keyboard controller (KBC)), a ROM-BIOS (BIOS), a central processing unit and a temperature sensor at least.
When this starting up for computer, can carry out initialization (step S11) to this embedded controller earlier, this embedded controller starts the computer system (step S12) of this computer apparatus then.Then, this embedded controller is obtained one of this a setting ROM-BIOS temperature upper limit and a lowest temperature value (step S13), and obtains the temperature (step S14) of this central processing unit by this temperature sensor.This embedded controller is detected the temperature of this central processing unit, and judges whether the temperature of this central processing unit is higher than this temperature upper limit (step S15).
When the temperature of this central processing unit was higher than this temperature upper limit, this embedded controller sent system control interruption or system management interrupt incident (being higher than ceiling temperature) is given this ROM-BIOS (step S16).Interrupt or this system management interrupt incident when receiving this system's control, this ROM-BIOS starts throttling (Throttling) function to carry out a throttle operation (step S17) to this central processing unit,, this central processing unit reaches the purpose of cooling so that can reducing operation time, perhaps close this computer system (step S18), begin to carry out from step S11 when treating startup next time computer system.
If the temperature of this central processing unit is not higher than this temperature upper limit, this embedded controller judges whether the temperature of this central processing unit is lower than this lowest temperature value (step S19).When the temperature of this central processing unit was lower than this lowest temperature value, this embedded controller sent another system's control interruption or system management interrupt incident (being lower than lower limit temperature) is given this ROM-BIOS (step S20).Interrupt or this system management interrupt incident when receiving this system's control, this ROM-BIOS is carried out another throttle operation to this central processing unit,, this central processing unit reaches the purpose of cooling so that can reducing operation time, perhaps close this throttling function, so that this central processing unit can operate (step S21) at full speed.
After executing this throttle operation or closing this throttling function, this ROM-BIOS is promptly reseted a temperature upper limit and a lowest temperature value, and this temperature upper limit that will reset and this lowest temperature value send this embedded controller (step S22) to.If the temperature of this central processing unit is not lower than this lowest temperature value, then this embedded controller continues to obtain by this temperature sensor the temperature (step S14) of this central processing unit, and repeating step S15～step S22.
