Lenovo W530 Rainbow Screen Glitch

Here is what I experienced last evening.

My laptop was high on drugs I guess, but it was not...

"This issue is mechanical in nature and not related to software."

...is what I discovered reading the paper published on Lenovo Support site.

I had no external LCD monitor to help me with the issue, but I was able to recover screen state and not lose the stuff I was working on by putting laptop into sleep mode.
