Since laptops don't have any controls, don't change anything, don't attempt to modify anything via the intel control panel.
Let CalPC handle the grayscale control if you don't have hardware monitor controls.
In the PC space ICC profiles handle gamut in ICC aware applications.
OK, so let me rephrase that to see if I have it straight, especially since I plan on calibrating LOTS of laptops in the future.
Laptops don't have hardware controls for their displays, so it's all handled internally with profiles. Changing the internal controls manually (outside of Calman or CalPC) is in essence creating a profile but it's not a profile created by Calman, which is what you're trying to do. Also, on the PC-single monitor workflow, some of those layouts are in-applicable for laptop calibrations (I'm thinking of the color temperature and RGB balance layouts).
Does this mean laptop calibrations are not as accurate as their PC counter parts? I wouldn't think so, because going back over the color temp and RGB balance layouts AFTER running the gray scale calibration shows PERFECT color temp and excellent RGB balance. Also, the resultant picture quality is stunning when compared to the pre-calibration image! (Aside from the fact that the display itself sucks and the primaries are no where close to 709... Secondaries were pretty good.)
So... couldn't you skip all that color temp and RGB balance garbage on a PC as well, and just run the gray scale corrections, then double check the color temp, etc?
Edit: Or, maybe the color temp and RGB balance is intended to be fixed FIRST, using the display device controls, before an internal profile is created to further perfect?
