I have in the past had a lot of problems with my Nvidia K2000M on my W530. Windows have kept disabling this due to "code 43" (Yellow triangle by the display driver).
I have solved this by reinstalling Nvidia drivers, but when this happened every 3 days or so, I started to suspect something was wrong.
And I believe I was right.... I tried to uninstall the driver (probably a mistake) before reinstalling the driver, but now the graphics card cannot be detected at all. When I try to install Nvidia drivers I get the following error message:
"NVIDIA Installer cannot continue. This graphics driver could not find compatible graphics hardware".
I also tried to disable optimus in BIOS, and enabled discrete graphics to try to force the computer to find the NVIDIA graphics card, but this obviously didn´t work. The computer then starts up with low graphcis and bad resolution. Under "Display adapters" in Device Manager there is no card detected at all (As the Intel integrated was disabled).
So, is my NVIDIA graphics card defective, or is there som other solution to try to detect it?
PS! I Also did a system update through Lenovos update center. Updated firmware in BIOS etc. This did not solve the problem.....

Honestly it sounds like the gpu might have stopped working for you. Another thing I could think of is trying to boot knoppix on the machine and watching when it detects the GPUs. You should be able to catch that. If it only lists one GPU in optimus mode its likely your Quadro is toast. Sad.

Is the BIOS set back to Optimus? It sounds like the chip is not working, but I would try a reinstall of windows before giving up.

Have you considered a hard powered down?
-Stripping the RAM, HDD, ODD
-Clearing the CMOS battery (i.e. disconnector the CMOS/CR2025 battery connector from the motherboard for 1 minute).
-After that, hold the power button (ensure that all the power is disconnected - battery, power adapter etc) for 30 seconds.
Reinstall and try to boot it up, re-selecting optimus. See if that works.
I think the chip may really have burnt out depending on how it was treated, but it's worth a shot!

It's worth checking, anyway (since you are going to have to remove the embedded keyboard) that you check the discrete graphics chip for any physical abnormalities. If there are then this is really an open and shut case.
Depending on the age of your computer/power adapter, consider if the power adapter (although unlikely) is no longer able to supply enough power to the computer to cause the graphics chip to not startup.
P.S. As with all computer 'surgeries', please observe the procedures of static discharge before opening up your PC.
