Patent number: 8212422Abstract: The hand-held electronic device includes a central processing unit, a memory unit, a state-detecting unit, a state-determining unit, a main power supply unit, a standby power supply unit, and a power supply switching unit. After determining the presence of a fall state, the state-determining unit will output a fall instruction and which causes the central processing unit to enter a low current mode; meanwhile, the power supply switching unit monitors power output and continues to supply low-potential power. In case of a fall of the hand-held electronic device, the device and method protect operation data and reduce the otherwise power-consuming current. The less power-consuming current is conducive to the reduction of capacitance required for a backup battery. The low current mode is effective in reducing the time taken to recover the operation mode of the electronic device.Type: GrantFiled: November 24, 2009Date of Patent: July 3, 2012Assignee: Askey Computer Corp.Inventors: Wen-Yu Chen, Ching-Feng Hsieh
