Problems solved by technology

[0006] For example, China Taiwan Patent Application No. 92200894 discloses a "wireless remote control that can be stored in its PCMCIA slot of a notebook computer". This wireless remote control generates power transmission, that is, it cannot make the laptop charge the wireless remote control
Therefore, the wireless remote control still needs to use batteries as a power source, and after a period of use, the batteries need to be replaced, which reduces its convenience.

Embodiment Construction

[0025] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail with accompanying drawings.

[0026] The present invention firstly provides a system for providing power by using a PCMCIA slot. Please refer to figure 1 , which is a system for providing power using a PCMCIA slot according to the present invention.

[0027] Such as figure 1 As shown, the system of the present invention is applied in a computer 5, which can provide power from the PCMCIA slot 56 to an external specific device 100. Wherein, the so-called "specific device" 100 of the present invention refers to can be inserted in the PCMCIA slot 56, and is electrically connected with PCMCIA slot 56, but under the basis of prior art, can't provide electric power by PCMCIA slot 56 Any device (eg a PCMCIA device without a PCMCIA interface IC).

[0028] Such as figure 1 As shown, when the specifi...

Abstract

A method of utilizing PCMCIA slot to supply power includes judging whether a specific unit is electric-inserted in said slot or not and judging whether said specific unit has PCMCIA boundary IC or not, utilizing PCMCIA slot to supply power to specific unit by controlling register bit of PCMCIA controller if said specific unit is electric-inserted in PCMCIA slot and said specific unit has no PCMCIA boundary IC.

Description

technical field [0001] The invention relates to an application of a PCMCIA slot, in particular to a method and a system for providing power by using the PCMCIA slot. Background technique [0002] The main specifications of the PCMCIA (Personal Computer Memory Card Interface Association) card (or PC card for short) were formulated by the Personal Memory Card International Organization in June 1998, and it has become an expansion device standard for notebook computers, which can be widely used in connection Computers and computer aids. Due to the limitation of the size of the notebook computer host (host), it is often necessary for users to connect external auxiliary devices to expand the functions of the computer. At this time, the PC card becomes the best interface. [0003] So far, the biggest function of PC card is to be a data transmission or area network card for notebook computers, so as to avoid the trouble of carrying bulky auxiliary equipment for users. Because it...
