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.
