Abstract
The instant invention broadly contemplates an energy saving subsystem comprising a secondary CPU that utilizes less power than a main CPU, thereby allowing an electronic device (e.g. a laptop PC) having the secondary CPU to use less power and run for longer periods of time on a limited power supply. Thus, the invention permits the electronic device to be utilized for extended periods and extends the battery life.
Claims19
An apparatus comprising:
- a central processing unit card, the central processing unit card comprising:
- a secondary central processing unit;
- and
- a secondary memory in operable connection with the secondary central processing unit;
- wherein the secondary central processing unit is configured to execute a secondary operating system that selectively controls at least one component of a base system rather than a main central processing unit configured to execute a first operating system of the base system.
2 more elements
An apparatus comprising:
- (a) a base system, the base system comprising:
- a main central processing unit;
- and
- a system memory in operable connection with the main central processing unit, the main central processing unit being configured to execute a first operating system;
- and
- (b) a central processing unit card, the central processing unit card comprising:
- a secondary central processing unit;
- and
- a secondary memory in operable connection with the secondary central processing unit, the secondary central processing unit being configured to execute a secondary operating system;
- wherein the secondary operating system selectively controls at least one component of the base system rather than the first operating system.
7 more elements
An apparatus comprising:
- (a) a base system comprising:
- a main central processing unit;
- and
- a system memory in operable connection with the main central processing unit, the main central processing unit being configured to execute a first operating system;
- and
- (b) a subsystem in operable connection with the base system;
- the subsystem comprising:
- a secondary central processing unit;
- and
- a subsystem memory in operable connection with the secondary central processing unit, the secondary central processing unit being configured to execute a secondary operating system;
- wherein the subsystem is configured to selectively control the apparatus rather than the base system in response to a pre-boot instruction.
