Abstract
The present invention provides a portable computer. In one aspect, the portable computer has a first power mode and a second power mode. The portable computer includes a memory bus and a control system coupled to the memory bus. The control system is configured to operate the memory bus at a first speed in the first power mode and a second speed different than a first speed in a second power mode.
Claims26
A portable computer having a first power mode and a second power mode, comprising:
- a memory bus;
- and
- a control system coupled to the memory bus, wherein the control system is configured to operate the memory bus at a first speed in the first power mode, and a second speed different than the first speed in the second power mode.
A computer having a first battery power mode and a second external power mode, the computer comprising:
- a memory;
- a memory bus in communication with the memory;
- and
- a control system coupled to the memory bus for reading and writing the memory, the control system including a clock generator, wherein the control system is configured to operate the memory bus at a first clock speed in the first battery power mode, and a second clock speed greater than the first clock speed in the second power mode.
A mobile computing device having a first battery power mode and a second external power mode, the computer comprising:
- a memory;
- a memory bus in communication with the memory;
- and a control system coupled to the memory bus for reading and writing the memory, the control system including a clock generator, wherein the control system is configured to operate the memory bus at a first clock speed in the first battery power mode, and a second clock speed greater than the first clock speed in the second power mode.
A method of managing power in a mobile computing device comprising:
- determining whether the mobile computing device is operating in a first power mode or a second power mode;
- operating the memory bus at a first bus speed when the mobile computing device is in the first power mode;
- and
- operating the memory bus at a second bus speed different from the first bus speed when the mobile computing device is in the second power mode.
A graphical user interface for use in a mobile computing device comprising:
- a first power mode selection include a slow memory bus selection and a fast memory bus selection;
- and
- a second power mode selection including a slow memory bus speed selection and a fast memory bus speed selection.
