In the main CPU/OS based state one or more components of the computing system are inactivated so as to cause the computing system to consume less power in the main CPU/OS based state than in the normal on state. The computing system is able to execute software application routines on a main CPU and a main OS of the computing system while in the main CPU/OS based state.
2. The method of claim 1 wherein said passing comprises passing the data object through an Application Program Interface, (�API�) of said non main OS that remains active while said main CPU and said main OS are sleeping.
6. The method of claim 1 wherein said data object describes �to-do� information.
9. A machine readable storage medium of claim 8 wherein said passing comprises passing the data object through an Application Program Interface, (�API�) of said non main Operating System, (�OS�) that remains active while said main CPU is sleeping.
13. A machine readable storage medium of claim 7 wherein said data object describes �to-do� information.
This application is a divisional of U.S. patent application Ser. No. 10/367,240 entitled �Computing System with Operational Low Power States�, filed on Feb. 14, 2003, now U.S. Pat. No. 7,114,090, issued on Sep. 26, 2006.
By contrast more elaborate non main CPU/OS state 305 hardware implementations are presently envisioned that can be viewed as lower power/lower performance computing systems having identifiable software and I/O. FIG. 9 a shows an example. In the depiction of FIG. 9 a, a computing system is shown having a main CPU/OS based system (which include main CPU 901, cache 902, system memory 904, graphics controller 905, main display 906, etc.). Many major components of the main CPU/OS based system are deactivated while in the �non main CPU/OS based lover power� state. Similar to the scheme of FIGS. 4 a through 4 c, the components which are deactivated during the �non main CPU/OS based lower power� state are drawn as shaded regions in FIG. 9 a. Hence, according to the embodiment of FIG. 9 a, the computing system used to implement the �non main CPU/OS based lower power� state includes its own distinctive: 1) controller 917 (which may be implemented by a lower performance/lower power processor, microcontroller, logic state machine, etc. as compared to the main CPU); 2) primary memory 918 (which may be implemented with lower speed random access memory (RAM) and/or less dense RAM as compared to the main system memory 904); 3) user interface 925 (which may include a display 919, keyboard/buttons 920 and LED 924); 4) system bus 923; 5) I/O unit 922 (which may be implemented, as just one example, with storage resources such as a FLASH based memory or polymer based memory); and, 5) FLASH memory 921.
