<P>PROBLEM TO BE SOLVED: To provide an information processor capable of shifting the state of a device from an unusable state to a usable state by performing a simple operation and a device state control method for shifting the state of a device from an unusable state to a usable state. <P>SOLUTION: When a user instructs to restart a power supply to ODD7a, a Utility 13c orders a System BIOS13a to check the state of ODD7 (S103), and reads the device type information and the information on the state of power supply to the device from a register group in EC/KBC28 (S104 and S105). The System BIOS13a informs the Utility 13c of these pieces of information (S106). When the Utility 13c determines that the ODD7a is in the off-state of power supply based on the information on the state of power supply (S107 No), it orders the System BIOS13a to shift the state of power supply to the ODD7a to the on-state (S108). <P>COPYRIGHT: (C)2012,JPO&INPIT |
