Abstract
An embedded subsystem is coupled to a shared database is synchronized with the notebook and has access to the hard drive. The subsystem is in operation when the notebook is in low power mode.
Claims28
A method comprising:
- transitioning a central processing unit (CPU) of a computer system into a low power mode, the computer system having a memory,
- activating a low power subsystem when the CPU enters the low power mode, the low-power subsystem including a low power processor, an external interface and a low power memory;
- independent of the CPU, using the low power processor of the low power subsystem to access data contained within the computer system memory;
- and
- providing the accessed data through the external interface of the low-power subsystem.

An apparatus comprising:
- a computer system having a central processing unit, a system memory, a mass storage device, and a user interface, the computer system having a low-power mode;
- and
- a low-power subsystem in operation when the computer system enters the low-power mode, the low power subsystem having a low power processor, a low power subsystem memory and an external interface independent of the computer system, the low power processor providing access to the computer system when the computer system is in the low power mode and the external interface providing data accessed from the computer system externally.
A low-power subsystem comprising:
- a miniature display screen;
- a user input unit;
- a low-power subsystem memory;
- and
- a low-power processor coupled to the miniature display screen, to the user input unit, and to the memory, the low-power processor providing access for the miniature display screen and the user input unit to a connected computer system when the connected computer system is in a low-power mode.
