(5) embodiment
With reference to figure 2, it shows the portable computer 20 of lift-launch desktop computer of the present invention with processor, and it comprises desktop computer processor 21, a battery 22, a current detector 23, a clock pulse generator 24, a chipset 25, a storer 26 and a system power supply 27.
Desktop computer is working centres as portable computer 20 of the present invention with processor 21, and couple with clock pulse generator 24, it should be noted in Fig. 2, desktop computer is directly to couple with clock pulse generator 24 with processor 21, but coupling mode between the two is not limited to this, and desktop computer also can couple with clock pulse generator 24 via chipset 25 with processor 21.
In addition, clock pulse generator 24 can in have a conversion table 241, make clock pulse generator 24 produce clock signal according to the change signal; For instance, conversion table 241 can be as shown in Figure 3, be divided into general value A and reduction value B, the current value that provides when battery 22 is during greater than reference value, desktop computer can be changed to reduction value B with the frequency of operation of processor 21 from general value A via conversion table 241, and then reduce the electric current of battery 22 required supplies; Relatively, when the current value that provides when battery 22 is reduced to less than reference value, desktop computer can be changed to general value A from reduction value B again with the frequency of operation of processor 21 via conversion table 241, desktop computer can be replied under the general work frequency with processor 21 work; Will be appreciated that Fig. 3 only is one with reference to example, the form of conversion table is not limited to this.
Storer 26 couples with clock pulse generator 24, and its frequency of operation can change with the change of desktop computer with the frequency of operation of processor 21, but also can be independent of the outer running of desktop computer with processor 21.
The basic comprising of lift-launch desktop computer of the present invention with the portable computer 20 of processor more than has been described, below its method for managing power supply of explanation.
With reference to figure 4, lift-launch desktop computer of the present invention comprises the following steps: at first with the method for managing power supply of the portable computer of processor, provide a reference value (that is, 22 lowest high-current values that can supply of battery, this can learn in the specification table by battery manufacturers), shown in step S11, then, detect the current value that battery 22 is supplied by current detector 23, the current value of being supplied when battery 22 is during greater than reference value, via the built-in conversion table 241 of clock pulse generator 24, reduces the frequency of operation of desktop computer with processor 21, so that the battery 22 required current values that provide to be provided, shown in step S12; Then, continue to detect the current value that battery 22 is supplied by current detector 23, the current value of being supplied when battery 22 is during less than reference value, via the built-in conversion table 241 of clock pulse generator 24, improve the frequency of operation of desktop computer with processor 21, so that the battery 22 required current values that provide to be provided, shown in step S13, and then desktop computer can be replied under the general work frequency with processor 21 work.
Will be appreciated that above-mentioned steps S12 and above-mentioned steps S13 are that mode with the loop repeats, purpose is not only to make battery to be unlikely to operate under the situation of excess current, simultaneously desktop computer is worked as far as possible under the general work frequency with processor 21.
In addition, at the change desktop computer during, be that mode with linearity is to change with the frequency of operation of processor 21.
Because in method for managing power supply of the present invention, during maximal value that the current value of being supplied when battery 22 can provide greater than electric current, be via reducing the frequency of operation of desktop computer with processor 21, the battery 22 required current values that provide are provided, therefore desktop computer can't be as known with processor 21, and electric current interrupts fully and causes computer to work as machine.
Therefore, by portable computer and the method for managing power supply thereof of lift-launch desktop computer of the present invention with processor, it can prevent that battery from providing ongoing operation under the situation of excess current, and guarantees battery life; In addition, in order to ensure battery life, method for managing power supply of the present invention is to realize in the mode of reduction desktop computer with the frequency of operation of processor, therefore can't cause computer to work as machine as known, and cause user's inconvenience.
Though the present invention discloses as above with preferred embodiment; yet it is not in order to limit the present invention; any personage who has the knack of present technique; without departing from the spirit and scope of the present invention; all equivalence changes or equivalence is replaced when doing, so protection scope of the present invention is when looking being as the criterion that accompanying Claim defines.
