Abstract
A laptop computer has a first relatively powerful and fast data processor and a second relatively slower data processor. The first data processor has a higher power consumption factor than the second. A switch mechanism controls which of the two processors is operatively connected to the computer system components. When external power is available, the faster more powerful processor is used. When external power is unavailable and the computer must be operated from the internal power source, the second processor is used to drive the system components in order to provide a longer total operating duty cycle before the internal power source is exhausted.
