You are doing it incorrectly and not actually changing anything. It appears to me that you need to go to a tech and pay him / her to do for you what you cannot:
Hybrid Graphics GPU: Integrated
Power P-states: Not Supported
Driver Attributes: Final Retail
Driver Date/Size: 12/13/2013 11:24:31, 12151296 bytes
WHQL Logo'd: Yes
Driver: C:\Program Files\NVIDIA Corporation\Drs\nvdrsdb.bin, 10/31/2013 09:13:14, 1151380 bytes
AND there is no way to tell from any DxDiag report whether you have the right settings applied in the Geforce Control Panel.
