Abstract: A function key scan code is received from an external keyboard communicatively connected to the computing device. The function key scan code corresponds to a function key of the external keyboard having been pressed. Whether function keys of an internal keyboard of the computing device are configured in an action key mode is determined. In response to determining that the function keys of the internal keyboard of the computing device are configured in the action key mode, the function key scan code received from the external keyboard is converted to an action key scan code.

Abstract: A method for changing power states of a computer sends a shutdown event to all running applications before the computer goes to sleep to prevent data loss in a sleep state of the computer. Furthermore, the method stores a system memory image into a flash memory before the computer goes to the sleep state. Moreover, the method restores the system memory image from the flash memory to the system memory when the computer exit the sleep state to come back the work state.
