First Claim
Patent Images
1. 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.

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.

19. 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.
