Embodiment
First embodiment
See also shown in Figure 2, the electricity saver of portable computer of the present invention, comprise a switch 11, one control circuit 15, one power supply 10 and a built-in device 13, switch 11 is in order to the required electric power of built-in device 13 runnings of control portable computer (NB), two ends electrically connect with power supply 10 and built-in device 13 respectively, and this switch 11 includes a manual switch 111 and an electric-controlled switch 112, hand switch 111 is located at portable computer (NB) and is gone up as the keying of input equipment with control electric-controlled switch 112, and the central processing system (CPU) that this control circuit 15 is (NB) in the portable computer, and two ends electrically connect with power supply 10 and built-in device 13 respectively, and built-in again device 13 can comprise CD-ROM device or bluetooth system devices such as (Bluetooth).
When the user does not temporarily use built-in device 13, then press hand switch 111, this moment, hand switch 111 was passed to electric-controlled switch 112 with shutdown signal, give an order to control circuit 15 by electric-controlled switch 112, and then control power supply 10 is not supplied with built-in device 13 electric power, portable computer (NB) but then still normal operation of remainder, if in the time of need re-using built-in device 13, press hand switch 111 again start signal is passed to electric-controlled switch 112, give an order to this control circuit 15 by electric-controlled switch 112, power supply 10 was received the instruction of control circuit 15 and was recovered power supply to built-in device 13 again this moment.In addition, the electric-controlled switch 112 of present embodiment is mos field effect transistor (MOSFET), and the hand switch 111 of portable computer among Fig. 5 ' be pushbutton switch, the portable computer of Fig. 6 with the form of keyboard as hand switch 111 " enforcement.
Second embodiment
See also Fig. 3,4a, 4b, shown in 5, comprise a switch 21, one control circuit 25, one power supply 20 and a built-in device 23, switch 21 is in order to provide the portable computer running required electric power, two ends electrically connect with power supply 20 and built-in device 23 respectively, and this switch 21 includes a manual switch 211 and an electric-controlled switch 212, hand switch 211 is located on the portable computer as the keying of input equipment with control electric-controlled switch 212, and this control circuit 25 is the central processing system (CPU) in the portable computer, and two ends electrically connect with power supply 20 and built-in device 23 respectively, and built-in again device 23 is CD-ROM device or bluetooth system (Bluetooth).
Have electronic type in the control circuit 25 and drive interfacial level controller (IDE Controller) and electronic type driving bus interface (IDE Bus) (not shown), when the user temporarily need not use built-in device 23, promptly shutdown signal is passed to telecommunication switch 212 by hand switch 211, give an order by 212 pairs of control circuits 25 of telecommunication switch again, control circuit 25 meetings this moment utilize electronic type driving interfacial level controller (IDE Controller) wherein earlier built-in device 23 to be produced a high impedance signal 251, and drive bus interface (IDE Bus) by electronic type and transmit this high impedance signal 251, after built-in device 23 receives this high impedance signal, 20 electric power (the t1 time of Fig. 4 a) that are supplied to built-in device 23 of cutting off the electricity supply again, voltage in the built-in device 23 can (be reduced to 0V by 5V) shown in Fig. 4 a at this moment, though so design can guarantee that voltage is different between built-in device 23 and the portable computer, the but phenomenon that can not leak electricity, and cause shorten the serviceable life of built-in device 23.On the contrary, when the user utilizes switch 21 that built-in device 23 is opened, what start signal was same is passed to electric-controlled switch 212 via hand switch 211, via electric-controlled switch 212 signal is passed in the control circuit 25, make power supply 20 earlier the electric power of power supply be fed built-in device 23 (the t2 time of Fig. 4 b, this moment, voltage was shown in Fig. 4 b, rise to 5V by 0V), electronic type driving interfacial level controller by control circuit 25 produces a no resistance signal 252 again, and drive bus interface (IDE Bus) by electronic type and transmit this no resistance signal 252, built-in device 23 and portable computer are electrically connected, avoid between built-in device 23 and the portable computer voltage different, and the influence of generation electric leakage, this mode can effectively be avoided when built-in device 23 and portable computer electrically connect or cut off electric power, owing to the different facts that cause leaking electricity of voltage height take place, in addition, the hand switch 211 of portable computer among Fig. 5 ' be pushbutton switch, the portable computer of Fig. 6 with the form of keyboard as hand switch 211 " enforcement.
