As for power management, i will post more link evening at 7pm wen my work is over.
thanks for reply
i am looking scenario exactly what you said!!
like "cutting off power supply to unwanted device and peripherals like camera,speaker,vibration motor etc"
And one more thing i was facing problem with GPRS connection
the scenario something like this data enabled option disable and enable.
equesting data connection to APN 'TATA.DOCOMO.INTERNET'
D/AT ( 357): AT> ATH
D/AT ( 357): AT> AT+CGREG=1
D/AT ( 357): AT> AT^SGAUTH=0
D/AT ( 357): AT> AT+CGACT=1
D/AT ( 357): AT> AT+CGDCONT=1,"IP","TATA.DOCOMO.INTERNET",,0,0
D/AT ( 357): AT> AT+CGQREQ=1
D/AT ( 357): AT> AT+CGQMIN=1
D/AT ( 357): AT> AT+CGEREP=1,0
D/AT ( 357): AT> ATD*99***1#
E/RIL ( 357): HERE WE RUN INTO AN ERROR
here i don't get what is the problem first time these AT commands got successes OK response.
but if call onRequest: SETUP_DATA_CALL function second time then these at commands responses are failed .
now i am working with testing people,then i got this problem if have time please check this once

sorry for late reply i was kind of busy...
and u can find it's manuals at TI site i guess.
BUT the power states u mentioned are CPU/system power states.From what i understand, u r trying to do basic power management like cutting off power supply to unwanted device and peripherals like camera,speaker,vibration motor etc. when not in use. The above links will lead u in that direction(not directly but eventually). The link Arun mentioned deals with info on what devices stay active or inactive in each of the power states & try to optimize consumtion and not how to control and interface them. Interfacing them and getting power management to work in different(links i mentioned) AND Managing and optimizing the power consumption is different(links Arun mentioned) . Only one of these will help u. Choose which stage u r in exactly
If u get back on what exactly u r trying to do, i can help more.
