Color calibration problem with W520

I got my new W520 yesterday, and every time I try to calibrate the display using the built in calibrator it runs through for a few minutes before giving the following error:

Error with measurement data. Please check your display patches measurements​

It starts when I close the lid as it should and makes an occasional chirp.
The screen is not dimming or turning off (set to never). Screensaver is off.
I am not opening it up, the lid is properly closed.
No other programs are running.
I have tried uninstalling the program and installing the one found on the Lenovo website, which has no effect.
The calibrator itself is not dirty.

Am I meant to have upgraded the graphics drivers/disabled Optimus/enabled a setting somewhere? Has anyone else had the same problem?

 

I got mine today, and experienced a similar problem, except that the error message was different: "Error calibrating display". The only change I had made so far (I had just completed initial configuration and creating the recovery media disks) was to change "Display resolution" -> "Make text larger or smaller" to use large text (Windows 7/64). After failing ten times in succession to make the color calibrator work, I decided to try re-setting this to the "medium" (default) setting, and the very first trial after that succeeded! So now it works at the factory setting for screen resolution, but appears to fail at the "large text" setting ... of course, the error message is not helpful at all! You might want to check if this sort of a thing is causing problems for you too ...

Best of luck!

 

Anyone have another solution, last format I could calibrate fine, now I have formatted twice without any luck, its really starting to me off that it only works 1/5 of the times and the error message is completely useless! What drivers should I install before I run the calibration for it to succeed?
