WIRELESS COMMUNICATION DEVICE AND METHOD OF SWITCHING POWER SUPPLY |
| 摘要 |
A power detector (222) produces a signal indicating that a computer device (103) is driven on an external power supply (107). If such a signal is not sent from the power detector (222) to a power supply control (203) through a signal transmission interface (212), then the power supply control (203) switches to operate a wireless communication device (101) on a battery (204) built in the communication device. |
