look here for the manual :  http://www.laptoprepair101.com/laptop/2008/01/07/service-manuals-for-sony-vaio-laptops-notebooks/

here my laptop troubleshooting guide :
- if no display - test with an external monitor
- test also with a known good battery !
- remove battery and AC adaptor, hold power button for 20 sec, connect AC and reboot --> any display ? if NO -->
- disconnect all disk and cd drives, battery , and other cards and peripherals, leave only 1 ram stick
- boot -->any display ?
- if NO remove all ram and reboot --> if NO beeps, mobo or cpu bad ; if it beeps, replace ram stick

If your AC adapter is puting out the right voltage then most likely it is your power jack on the mother board.
I usually can repair the power jack on the mother board with out geting a new one.
Laptop was sent torepir. They have to repalce some components on motherboeard. Its working fine now.
