A computer system having at least three states of power management: a normal operating state, a standby state, and a suspend state. The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system. The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive. Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. As the standby state is entered, the state of the computer system is saved to a file on the hard drive in such a manner that if system power is accidently removed after the state of the computer system is saved to the hard drive, then the state of the computer system can be resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. The data saved as the system enters the standby state is invalidated if the system meets certain conditions.
